description: Agricultural production, processing, and retail industries are major contributors to Arkansas’ GDP. Agriculture contributes to the state economy through direct agricultural production, value-added processing, and agricultural retail activities. The Agriculture and Food Sector, which is comprised of agricultural production, processing, and retail industries, promotes economic strength through various interactions with other industries. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy and thus plays a vital role in maintaining economic stability throughout the state. This report 1) compares the relative size of the Agriculture and Food Sector in Arkansas with those of neighboring states; 2) provides an overview of Arkansas’ economy and discusses Arkansas’ agricultural sector in relation to the state economy; and 3) examines components of agricultural production and processing, including a review of historical sales trends for raw and processed agricultural output.

description: The quantum phase transitions induced by a magnetic field are theoretically studied in a frustrated two-leg spin ladder. Using the density-matrix renormalization-group method, we find some magnetic phase transitions and plateaux in two different cases of strong and weak rung couplings. With the strong rung coupling, the three magnetization plateaux are found at 1/3, 1/2, and 2/3 due to the frustration. Those can be understood in terms of a quasi-spinon reconstructed from the singlet and the triplets of spins on a rung. The plateau at 1/2 corresponds to the valence bond solid of the quasi-spinons, while the plateaux at 1/3 and 2/3 can be associated with the array of quasi-spinons such as soliton lattice. This is different from the usual Bose-Einstein-condensation picture of triplons. Our results will be useful to understand magnetization curves in BiCu$_2$PO$_6$.

description: Dopamine (DA) is the major physiological regulator of prolactin secretion from the anterior pituitary, exerting a tonic inhibitory control that is mediated by D2 DA receptors. D2 receptors in both the anterior pituitary and CNS are thought to produce some of their inhibitory effects via a coupling to potassium (K+) channels to increase K+ conductance. Utilizing the reverse hemolytic plaque assay and patch-clamp techniques, we characterize the actions of DA on membrane potential and associated DA-activated whole-cell current, as well as the single K+ channels that underlie the response in primary rat lactotrophs. We demonstrate that DA (5 nM to 1 microM) or D2- selective agonists (RU24213 and quinpirole) evoke a hyperpolarization of membrane potential that was blocked by D2 antagonists and associated with an increased K+ conductance. Whole-cell current responses to ramp voltage commands revealed a DA-activated current whose reversal potential was near the calculated Nernst potential for K+, varied as a function of K+ concentration, exhibited some inward rectification, and was Ca2+ independent. The current was insensitive to tetraethylammonium (TEA; 10 mM), partially blocked by 4-aminopyridine (4-AP; 5 mM), and almost completely inhibited by quinine (100 microM). Cell-attached recordings in the presence of DA or a D2 agonist revealed the opening of a K+ channel that was not present in the absence of DA or when a D2 receptor antagonist was included with DA. Analysis of the single- channel current showed the current-voltage relationship to be linear at negative patch potentials and yielded a unitary conductance of 40.2 pS in the presence of 150 mM KCl. The channels were not blocked by TEA (10 mM), were slightly suppressed by 4-AP (5 mM), and were almost completely inhibited by quinine (100 microM). These experiments establish that in primary rat lactotrophs, DA acts at D2 receptors to activate the opening of single K+ channels, which results in an increase in K+ conductance and associated membrane hyperpolarization. This is the first characterization of single DA-activated K+ channels in an endocrine cell.

description: The zero-temperature phase diagram of $p$-orbital two-component fermionic system loaded into a one-dimensional optical lattice is mapped out by means of analytical and numerical techniques. It is shown that the $p$-band model away from half-filling hosts various competing superconducting phases for attractive and repulsive interactions. At quarter filling, we analyze the possible formation of incompressible Mott phases and in particular for repulsive interactions, we find the occurrence of a Mott transition with the formation of fully gapped bond-ordering waves.

description: Although rapid-onset, short-term regulation of neuronal Ca currents by neurotransmitters and second messengers is well documented, little is known about conditions that can cause longer-lasting changes in Ca channel function. We report here that persistent depolarization is accompanied by slowly developing long-term reduction of neuronal Ca currents. Rat myenteric neurons grown in cell culture for 1–7 d were studied with the tight-seal whole-cell recording technique. Macroscopic Ca-channel currents had decaying and sustained components at all days studied. When the neurons were grown in medium containing 25 mM KCl, which depolarized them to -40 mV and caused significant elevation of intracellular Ca, the densities of both components of Ca-channel current decreased by 40–80%. Several results suggest that different mechanisms underlie the downregulation of the two components. (1) The density of the decaying component decreased approximately four times faster than did that of the sustained component. (2) When neurons were returned to control medium, which contained 5 mM KCl, the density of the sustained component returned to control levels within 24 hr, while that of the decaying component did not recover significantly. (3) Inhibitors of RNA and protein synthesis reduced or prevented downregulation of the sustained but not of the decaying component. (4) The dihydropyridine antagonist nitrendipine, which prevented the sustained elevation of intracellular Ca in neurons grown in 25 mM KCl, prevented downregulation of the sustained component but had no effect on downregulation of the decaying component. We suggest that these forms of regulation of Ca current density could help neurons adapt to altered levels of electrical activity and may contribute to changes in synaptic strength that occur during periods of increased or decreased electrical activity.

description: This article investigates how European universities (EU27+UK) respond to different types of incentives, namely, funding derived from: a) core government allocation, b) external sources (i.e., third-party funding), and c) students’ tuition fees. The general research question we address is: how does universities’ performance respond and adjust to different funding government policies and universities’ strategies? We perform an exploratory analysis based on two methodological pillars: 1) the use of the RISIS-ETER database, providing a register of European Higher Education Institutions and containing basic statistical information on them, including descriptors on geographical location, students and graduates, personnel, finances, and research activities; 2) the responsiveness-score econometric model, aimed at testing separately the response of each university toward core funding, third-party funding, and tuition fees. Specifically, we aim at investigating specific research issues, in particular: a) the universities’ positioning in terms of the capacity to respond to specific policy measures; b) the identification of the main policy factors that universities’ performance; c) the response heterogeneity to different funding inputs; d) the study of the phenomenon of convergence (divergence) taking place in universities’ performance.

description: Exposure of developing rats to tellurium results in a highly synchronous segmental demyelination of peripheral nerves with sparing of axons; this demyelination is followed closely by a period of rapid remyelination. Demyelination occurs subsequent to a tellurium-induced block in the synthesis of cholesterol, the major myelin lipid. We utilized the techniques of Northern blotting, in situ hybridization, and immunocytochemistry to examine temporal alterations in Schwann cell gene expression related to demyelination and remyelination. Tellurium- induced demyelination is associated with downregulation of myelin protein expression and a corresponding upregulation of NGF receptor (NGF-R) and glial fibrillary acidic protein (GFAP) expression. Steady- state mRNA levels (expressed on a “per nerve” basis) for P0, the major myelin protein, were decreased by about 50% after 5 d of tellurium exposure, while levels of mRNA for NGF-R and GFAP were markedly increased (about 15-fold). In situ hybridization of teased fibers suggested that the increase in steady-state mRNA levels for NGF-R was primarily associated with demyelinated internodes and not with adjacent unaffected internodes. Although P0 message was almost totally absent from demyelinating internodes, it was also reduced in normal-appearing internodes as well. This suggests that limiting the supply of a required membrane component (cholesterol) may lead to partial downregulation of myelin gene expression in all myelinating Schwann cells. In partially demyelinated internodes, NGF-R and GFAP immunofluorescence appeared largely confined to the demyelinated regions. This suggests specific targeting of these proteins to local areas of the Schwann cell where there is myelin loss. These results demonstrate that demyelination is associated with reversion of the affected Schwann cells to a precursor cell phenotype. Because axons remain intact, our results suggest that these changes in Schwann cell gene expression do not require input from a degenerating axon, but instead may depend on whether concerted synthesis of myelin is occurring.

description: This study analyzes the synaptic interactions between the central terminals of A delta high threshold mechanoreceptors (A delta HTMs) and GABA-immunoreactive profiles. A delta HTM primary afferents from three monkeys and one cat were electrophysiologically identified and intracellularly labeled with HRP, and their terminal arborizations in laminae I and II of the sacrocaudal spinal cord were studied at the ultrastructural level. GABA-immunoreactive profiles in relation to A delta HTM terminals were demonstrated using postembedding colloidal gold techniques. Monkey A delta HTM terminals (n = 131) usually constituted the central element of synaptic glomeruli; they established large asymmetric synaptic contacts with 1-13 dendrites (modal value 2- 4) and were surrounded by 0-6 peripheral axon terminals (modal value 2- 3). The large majority (around 85%) of the peripheral axon terminals were GABA immunoreactive. They were found presynaptic to the A delta HTM terminal and/or to dendrites postsynaptic to the primary afferent terminal. Furthermore, all peripheral axon terminals found presynaptic to the A delta HTM terminals showed GABA immunoreactivity. Within a single A delta HTM fiber, this synaptic arrangement was found in 20-60% of its boutons. In addition, 28% of the postsynaptic dendritic profiles displayed weak GABA immunoreactivity. Some of them contained vesicles; however, only in a few cases did we observe synapses between a GABA- immunoreactive vesicle-containing dendrite and a dendritic profile postsynaptic to an A delta HTM terminal. Similar synaptology and interactions with GABA-immunoreactive profiles were displayed by the terminals of the single cat A delta HTM fiber studied. Our data support the hypothesis that GABA-containing neurons use both presynaptic and/or postsynaptic mechanisms to exert a powerful control, presumably inhibitory, over the transmission of nociceptive information between A delta HTM afferents and second-order neurons in monkey and cat spinal cord. Our results also imply that GABA may be released within the synaptic glomeruli formed by A delta HTM terminals either by local dendrites or by axon terminals. We discuss the possibility that these GABAergic synapses can be driven by inputs from both primary afferents and/or descending systems to modulate the transmission of nociceptive sensory information.

description: We present the results obtained from linear stability analysis and 2.5-dimensional magnetohydrodynamic (MHD) simulations of the magnetorotational instability (MRI), including the effects of cosmic rays (CRs). We took into account of the CR diffusion along the magnetic field but neglect the cross-field-line diffusion. Two models are considered in this paper: shearing box model and differentially rotating cylinder model. We studied how MRI is affected by the initial CR pressure (i.e., energy) distribution. In the shearing box model, the initial state is uniform distribution. Linear analysis shows that the growth rate of MRI does not depend on the value of CR diffusion coefficient. In the differentially rotating cylinder model, the initial state is a constant angular momentum polytropic disk threaded by weak uniform vertical magnetic field. Linear analysis shows that the growth rate of MRI becomes larger if the CR diffusion coefficient is larger. Both results are confirmed by MHD simulations. The MHD simulation results show that the outward movement of matter by the growth of MRI is not impeded by the CR pressure gradient, and the centrifugal force which acts to the concentrated matter becomes larger. Consequently, the growth rate of MRI is increased. On the other hand, if the initial CR pressure is uniform, then the growth rate of the MRI barely depends on the value of the CR diffusion coefficient.

description: Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and value-added processing, leading to economic activity in other parts of the economy. This report is the fifteenth in a series that examines agriculture’s economic contribution to the Arkansas economy. The total economic contribution of agriculture (direct, indirect, and induced effects) on value added, employment, and labor income was estimated with the Impact Analysis for Planning System (IMPLAN) for the most recent year available, 2020.

description: At photoreceptor synapses, transmitter release is continuous and graded. At this type of synapse, the control of presynaptic [Ca2+]i and calcium's role in releasing transmitter might be different than at terminals invaded by all-or-none action potentials. To examine this possibility, we measured the spatial and temporal changes of [Ca2+]i in response to depolarization of individual photoreceptor terminals of the barnacle Balanus nubilus, which had been injected with the Ca2+ indicator Fura-2. Depolarizing pulses produced voltage-dependent Ca2+ entry that was confined to the tips of the arbor where the release sites are located. At increasing distances from the tips, the rate of [Ca2+]i increase was slower and the peak [Ca2+]i occurred later, suggesting that Ca2+ entered the tips and diffused back into the larger processes of the arbor. Consistent with this result, a stable gradient of [Ca2+]i was observed at maintained depolarizations, with the highest values at the tips of the arbor. Removal of external Na+ did not affect the time course of Ca2+ decline in the terminal, indicating that Na+/Ca2+ exchange was not the primary mechanism for restoring [Ca2+]i to basal levels. Computer simulations, assuming only Ca2+ entry at the arbor's tips and diffusion of Ca2+ away from the entry site, qualitatively reproduced these observations. The threshold for Ca2+ entry was near -60 mV, and entry was maintained during prolonged depolarizations, in agreement with previous experiments showing that Ca2+ channels in the terminal region do not inactivate. The time course of the measured [Ca2+]i change in the terminal paralleled voltage changes due to a Ca(2+)-activated K+ conductance, which senses [Ca2+]i just under the membrane. This parallelism is expected since the release sites are located on processes of small-enough diameter to permit radial equilibration of [Ca2+]i within the time course of physiological voltage changes. Therefore, the optical measurements reflect the mean level of [Ca2+]i under the membrane. Whether this mean concentration is also the value at the sites that trigger exocytosis will depend on how close the Ca2+ channels are to these sites.
Topographic patterns of brain activity in response to swim stress: assessment by 2-deoxyglucose uptake and expression of Fos-like immunoreactivity

description: Alterations in brain activity patterns were assessed in response to swim stress by immunocytochemical detection of Fos-like immunoreactivity (Fos-LI) and high-resolution autoradiographic imaging of 14C-2-deoxyglucose (2-DG) uptake. The stress paradigm investigated was a classic behavioral screen for antidepressant drug activity, the forced swim test. One of the most pronounced effects produced by swim stress was an increase in 2-DG uptake and induction of Fos-LI in a restricted region of the lateral septal nucleus. Specific "limbic" cortical regions, including the medial prefrontal, ventrolateral orbital, and cingulate cortices, also exhibited both increased 2-DG uptake and expression of Fos-LI in response to swim stress. In the hypothalamic paraventricular nucleus of swim-stressed rats, Fos-LI was induced but no change in 2-DG uptake was apparent. Since the specific swim stress protocol used is a behavioral screen for antidepressant drugs, the effects of imipramine on stress-induced alterations in 2-DG uptake and induction of Fos-LI were examined. The stress-induced increase in 2-DG uptake in the lateral septum was blocked by treatment with imipramine, but treatment with imipramine had no effect on induction of Fos-LI in the same region. Neither 2-DG uptake nor Fos-LI expression was altered by imipramine treatment in the cortical regions influenced by swim stress. Administration of imipramine alone under basal conditions produced a robust induction of Fos-LI in the central nucleus of the amygdala and in the dorsal lateral subdivision of the bed nucleus of the stria terminalis. No effect of imipramine treatment on 2-DG uptake was apparent in these latter regions. The results provide insights into topographic patterns of brain activity associated with swim stress and neuroanatomically selective actions of imipramine. The different and complementary information obtained by assessment of Fos-LI and 2-DG uptake illustrates the utility of applying both functional mapping approaches to examine neuroanatomical correlates of behavioral states and drug treatment.

description: We investigate the phase diagram of spinless fermions with nearest and next-nearest neighbour density-density interactions on the honeycomb lattice at half-filling. Using Exact Diagonalization techniques of the full Hamiltonian and constrained subspaces, combined with a careful choice of finite-size clusters, we determine the different charge orderings that occur for large interactions. In this regime we find a two-sublattice Néel-like state, a charge modulated state with a tripling of the unit cell, a zig-zag phase and a novel charge ordered states with a 12 site unit cells we call Néel domain wall crystal, as well as a region of phase separation for attractive interactions. A sizeable region of the phase diagram is classically degenerate, but it remains unclear whether an order-by-disorder mechanism will lift the degeneracy. For intermediate repulsion we find evidence for a Kekulé or plaquette bond-order wave phase. We also investigate the possibility of a spontaneous Chern insulator phase (dubbed topological Mott insulator), as previously put forward by several mean-field studies. Although we are unable to detect convincing evidence for this phase based on energy spectra and order parameters, we find an enhancement of current-current correlations with the expected spatial structure compared to the non-interacting situation. While for the studied $t{-}V_1{-}V_2$ model the phase transition to the putative topological Mott insulator is preempted by the phase transitions to the various ordered states, our findings might hint at the possibility for a topological Mott insulator in an enlarged Hamiltonian parameter space, where the competing phases are suppressed.

description: This paper describes the approach taken by Western Sydney University in the assessment of a turnkey research data management platform. Key recommendations from the Active Research Data Management Element of the Research Data Management Framework developed by the Australian Research Data Commons were implemented. WSU-derived research data are currently stored across many different silos and there is consideration of management of data through research data management plans. However, the use of metadata is not consistent and often non-existent. WSU trialled the use of the Idea package provided by Cloud Services provider Intersect, which is based on Mediaflux, for the management of research data throughout the full data lifecycle from collection to archiving. The Active Research Data Management Element provided useful insights into the assessment of Idea in the areas of data management, use of metadata, automated data workflows, research data governance and the criteria for platform selection.

description: We have generated a line of transgenic mice that when homozygous for the transgene develop a severe, adult-onset neuromuscular disorder. This mutation is likely the result of the insertional inactivation of an endogenous gene by the transgene integration. The mutant mice have a gait abnormality with stiffened and/or splayed hind legs, and adopt a hunched posture with some exhibiting kyphosis of the thoracic spine. These symptoms progress gradually to severe motor dysfunction. Pathologic changes were found in skeletal muscle and peripheral nerve of the mutant animals. In young mice the muscles from both upper and lower extremities show necrosis and phagocytosis. In older mice, regeneration with muscle fiber splitting, internally located nuclei, and variable fiber size are conspicuous features. Interactions between Schwann cells and axons also appear disrupted in these animals. Although many peripheral axons are well myelinated, the nerve and nerve roots contain very large bundles of juxtaposed, bare axons, reminiscent of Schwann cell-axon interactions in early development. Within these bundles there are axons large enough to be myelinated. The relationship between the pathologic changes in the muscles and nerves is not clear. The phenotypic abnormalities of these animals resemble those that occur in the spontaneous mouse mutants dystrophia muscularis and myodystrophy. Nevertheless, the chromosomal position of the transgene integration site, which was mapped by fluorescent in situ hybridization to chromosome 11, indicates that this disorder represents a new neuromuscular mutation.

description: The observation of hippocampal place cells forms a major line of evidence supporting the view that the hippocampus is dedicated to spatial processing. However, most studies demonstrating the spatial properties of hippocampal unit activity have employed tasks that emphasize spatial cues but minimize nonspatial cues. In the present experiment we recorded the activity of hippocampal complex-spike cells from rats performing a nonspatial radial maze task. Performance in this task was guided by local visual-tactile cues on the maze arms, while distal spatial cues were minimized and made irrelevant. The influence of three variables on unit activity was examined:type of cue on an arm, spatial location of an arm, and the relative position of the animal on an arm. Of the units recorded, almost one-fifth were classified as "cue cells" in that their activity was associated with cue type but not spatial location. Conversely, a similar proportion of the units were classified as "place cells" in that their activity was associated with location, but not cue type. In an additional similar proportion of units, firing was influenced only by relative position and not by local cues or spatial locations. For the majority of units, however, firing was related to combinations of these three variables, indicating that most hippocampal neurons encoded conjunctions or relations between spatial and local cue information. This pattern of results indicates that when local rather than distal spatial cues are emphasized, hippocampal neural activity is strongly influenced by salient nonspatial cues and shows no overwhelming predominance of place coding. These findings are at odds with the hypothesis that the hippocampus is selectively involved in spatial processing and, conversely, support the broader view that the hippocampus encodes both spatial and nonspatial relations among important experimental variables.

description: Western Sydney University has engaged Cloud Services provider Intersect to provide access to Mediaflux on an Intersect research data management platform called Idea . Idea has been designed with the intention of managing research data throughout the full data lifecycle from collection to archiving. WSU-derived research data are currently stored across many different silos and there is consideration of management of data through research data management plans. However, the use of metadata is not consistent. As part of the Australian Research Data Commons (ARDC) National Data Assets Initiative, the ARDC funded a collaborative multi-university Institutional Underpinnings project to develop a national Institutional Research Data Management Framework (the Framework). Several essential Elements to the Framework were developed, one of which is the Active Research Data Management Element . The intention of this Element is to provide “institutions with guidance to ensure that research practice is efficient and impactful, and that research data is managed according to requirements such as those outlined in The Australian Code for the Responsible Conduct of Research”. Our approach at Western Sydney University in implementation of the Active Research Data Management Element of the Framework was to take the turnkey Idea platform, configure using a default metadata schema and engage with researchers in ingesting live research project datasets. This case study evaluates the metadata schema to reflect active research datasets uploaded directly from a data source to the Idea research data repository. The Idea platform provides the ability for researchers to curate, manage, protect and disseminate research data. It will also provide the capacity for handling data from research instrument platforms as increasingly, the University’s research infrastructure requires a component that automates metadata creation and storage for aspects of the research cycle.
Different kinetics govern dopaminergic transmission in the amygdala, prefrontal cortex, and striatum: an in vivo voltammetric study

description: The regulation of extracellular dopamine (DA) concentrations was examined and compared in vivo in four projection fields of mesotelencephalic dopaminergic neurons with fast-scan cyclic voltammetry at carbon-fiber microelectrodes. Transient electrical stimulation of ascending DA fibers in a near physiological range of frequencies (10-20 Hz) elicited similar levels of extracellular DA in the medial prefrontal cortex (MPFC), basal lateral amygdaloid nucleus (BAN), caudate-putamen (CP), and nucleus accumbens (NAc) despite the documented 90-fold disparity in DA tissue levels and terminal density. However, marked differences were observed in the dynamics and overall frequency dependence of the evoked synaptic overflow of DA. These differences are due to the significantly different rates of release and uptake found in each of the four regions. For example, rate constants for the release of the four regions. For example, rate constants for the release and uptake of DA were similar in the MPFC and BAN but approximately 8 and 50 times less, respectively, than that in the CP and NAc. When the parameters were normalized to endogenous DA tissue content, a unique picture emerged: compared to all other regions, relative release was 10-fold greater in the MPFC while relative uptake was at least 10 times less in the BAN. The results further differentiate the functional characteristics of mesotelencephalic dopaminergic systems and demonstrate the regiospecific nature of DA neural transmission in the brain. In addition, the regulation of extracellular DA levels in the MPFC and BAN is suitable for the "long-range" transfer of chemical information in the brain and is consistent with a hypothesis of extrasynaptic neurotransmission.
On the micro-to-macro limit for first-order traffic flow models on networks

description: Connections between microscopic follow-the-leader and macroscopic fluid-dynamics traffic flow models are already well understood in the case of vehicles moving on a single road. Analogous connections in the case of road networks are instead lacking. This is probably due to the fact that macroscopic traffic models on networks are in general ill-posed, since the conservation of the mass is not sufficient alone to characterize a unique solution at junctions. This ambiguity makes more difficult to find the right limit of the microscopic model, which, in turn, can be defined in different ways near the junctions. In this paper we show that a natural extension of the first-order follow-the-leader model on networks corresponds, as the number of vehicles tends to infinity, to the LWR-based multi-path model introduced in [Bretti et al., Discrete Contin. Dyn. Syst. Ser. S, 7 (2014)] and [Briani and Cristiani, Netw. Heterog. Media, 9 (2014)].

description: We investigated the postnatal development of the thyrotropin-releasing hormone (TRH)-containing raphe system in the brainstem of neonatal rats. Postnatal changes in TRH expression in nucleus (n.) raphe obscurus (ROb) and n. raphe pallidus (RPa) were evaluated by in situ hybridization using an 35S-labeled oligonucleotide probe complementary to TRH precursor mRNA. TRH mRNA expression was low at birth [postnatal day 0 (P0)], but was clearly evident by P7 and increased from that time to reach sustained high levels from P14 to P28. Consistent with this postnatal increase in TRH expression, we found increases in the density of TRH-immunoreactive (IR) fibers, which are derived from ROb and RPa, in the hypoglossal nucleus (nXII). TRH-IR fibers in nXII were very sparse at P0, but increased markedly over the first 2 postnatal weeks. The change in TRH innervation of nXII was closely matched by concomitant increases in 3H-methyl-TRH binding in nXII; specific TRH binding increased from very low levels at birth to high levels of P14. Finally, we recorded intracellularly the electrophysiological responses to TRH of hypoglossal motoneurons (HMs; n = 42) of neonatal rats (P0- P21) in a brainstem slice preparation. The response of neonatal HMs to TRH, in contrast to adult HMs, was highly variable. In some neonatal HMs, even at P0, TRH caused a depolarization with a decrease in input conductance (GN) that was characteristic of the response of all adult HMs. However, in other neonatal HMs, TRH was either without effect or caused a slight depolarization with no apparent change in GN, responses that were unlike those of adult HMs. A response was considered typical (i.e., “adult-like”) if GN decreased to < 85% of control. The percentage of cells responding in a typical manner increased progressively from 25% at P0-P2 to 100% after P11. In addition, we found that the density of TRH-sensitive current (normalized to cell capacitance) increased with postnatal age in HMs that responded in a typical manner, suggesting that expression of the TRH-sensitive conductance is also developmentally regulated. Together, these data indicate that the TRH raphe neuronal system of the rat brainstem is not fully mature at the time of birth but develops over the first few postnatal weeks. This was true of levels of TRH mRNA in caudal raphe nuclei, density of TRH-IR fibers and 3H-methyl-TRH binding in nXII, and also the manner and magnitude of electrophysiological responses of HMs to exogenously applied TRH.

description: Individual animals can often move more safely or more efficiently as members of a group. This can be as simple as safety in numbers or as sophisticated as aerodynamic or hydrodynamic cooperation. Here, we show that individual plant–animal worms (Symsagittifera roscoffensis) can move to safety more quickly through flocculation. Flocs form in response to turbulence that might otherwise carry these beach-dwelling worms out to sea. They allow the worms to descend much more quickly to the safety of the substrate than single worms could swim. Descent speed increases with floc size such that larger flocs can catch up with smaller ones and engulf them to become even larger and faster. To our knowledge, this is the first demonstration of social flocculation in a wild, multicellular organism. It is also remarkable that such effective flocculation occurs where the components are comparatively large multicellular organisms organized as entangled ensembles.
