Depression and cardiovascular autonomic control: a matter of vagus and sex paradox.
Neuroscience and biobehavioral reviews, 2020

Depression is a well-established stress-related risk factor for several diseases, mainly for those with cardiovascular outcomes. The mechanisms that link depression disorders with cardiovascular diseases (CVD) include dysfunctions of the autonomic nervous system. Heart rate variability analysis is a widely-used non-invasive method that can simultaneously quantify the activity of the two branches of cardiac autonomic neural control and provide insights about their pathophysiological alterations. Recent scientific literature suggests that sex influences the relationship between depressive symptoms and cardiac autonomic dysfunction. Moreover, a few studies highlight a possible sex paradox: depressed women, despite a greater vagal tone, experience a higher risk of adverse cardiovascular events than depressed men. Although there are striking sex differences in the incidence of depression, scanty data on this topic are available. Lastly, studies on the heart-brain axis bidirectionality and the role of sex are fundamental not only to clarify the biological bases of depression-CVD comorbidity, but also to develop alternative therapies, where vagus nerve appears to be a promising target of non-invasive neuromodulation techniques.
Impact of maternal mental health interventions on child-related outcomes in low- and middle-income countries: a systematic review and meta-analysis.
Epidemiology and psychiatric sciences, 2020

Observational studies have shown a relationship between maternal mental health (MMH) and child development, but few studies have evaluated whether MMH interventions improve child-related outcomes, particularly in low- and middle-income countries. The objective of this review is to synthesise findings on the effectiveness of MMH interventions to improve child-related outcomes in low- and middle-income countries (LMICs).
M2 cortex-dorsolateral striatum stimulation reverses motor symptoms and synaptic deficits in Huntington's disease.
eLife, 2020

Huntington's disease (HD) is a neurological disorder characterized by motor disturbances. HD pathology is most prominent in the striatum, the central hub of the basal ganglia. The cerebral cortex is the main striatal afferent, and progressive cortico-striatal disconnection characterizes HD. We mapped striatal network dysfunction in HD mice to ultimately modulate the activity of a specific cortico-striatal circuit to ameliorate motor symptoms and recover synaptic plasticity. Multimodal MRI in vivo indicates cortico-striatal and thalamo-striatal functional network deficits and reduced glutamate/glutamine ratio in the striatum of HD mice. Moreover, optogenetically-induced glutamate release from M2 cortex terminals in the dorsolateral striatum (DLS) was undetectable in HD mice and striatal neurons show blunted electrophysiological responses. Remarkably, repeated M2-DLS optogenetic stimulation normalized motor behavior in HD mice and evoked a sustained increase of synaptic plasticity. Overall, these results reveal that selective stimulation of the M2-DLS pathway can become an effective therapeutic strategy in HD.
Fingers hold spatial information that toes do not.
Quarterly journal of experimental psychology (2006), 2021

Fingers have preferential associations with relative spatial locations. Tactile localisation is faster when the fingers are in these locations, such as when the index finger is in a relatively higher spatial position, and the thumb in a relatively lower position. However, it is unclear whether these associations are related to hands specifically, or are a more general characteristic of limbs. The present study therefore investigated whether toes have similar spatial associations. If these associations reflect the statistics of natural limb usage, very different patterns of association would be expected for the fingers and toes, given their different functional roles in daily behaviour. We measured reaction time (RT) and error rates of responses to tactile stimuli applied to the middle finger/toe or thumb/big toe, when they were positioned in a relative upper or lower location. We replicated the finding that fingers have preferential associations that facilitates localisation-RT and error rate were lower when the index finger was in the top position, and the thumb in the bottom position. We found that toes do not hold the same spatial information, though it remains unclear whether toes hold different spatial information or none at all. These results demonstrate spatial information held by the fingers is stronger and more reliable than for the toes, so is not a general characteristic of limbs, but possibly related to hand use.

Segment-specific optogenetic stimulation in Drosophila melanogaster with linear arrays of organic light-emitting diodes.
Nature communications, 2020

Optogenetics allows light-driven, non-contact control of neural systems, but light delivery remains challenging, in particular when fine spatial control of light is required to achieve local specificity. Here, we employ organic light-emitting diodes (OLEDs) that are micropatterned into linear arrays to obtain precise optogenetic control in Drosophila melanogaster larvae expressing the light-gated activator CsChrimson and the inhibitor GtACR2 within their peripheral sensory system. Our method allows confinement of light stimuli to within individual abdominal segments, which facilitates the study of larval behaviour in response to local sensory input. We show controlled triggering of specific crawling modes and find that targeted neurostimulation in abdominal segments switches the direction of crawling. More broadly, our work demonstrates how OLEDs can provide tailored patterns of light for photo-stimulation of neuronal networks, with future implications ranging from mapping neuronal connectivity in cultures to targeted photo-stimulation with pixelated OLED implants in vivo.

Chemical eye injury: pathophysiology, assessment and management.
Eye (London, England), 2020

Chemical eye injury (CEI) is an acute emergency which can threaten sight and life. These commonly occur at home or the workplace with the former being generally mild and the latter more severe and bilateral. Major workplace accidents involve other parts of the body and can be associated with inhalation or ingestion of the chemical. Alkali injuries cause damage by saponification of tissue and deeper penetration as a consequence. Acid injuries cause rapid coagulation of tissue, which impedes penetration and limits damage. Irritants such as alcohols, cause superficial epithelial denudation. Severe chemical insult can affect all anterior segment structures causing iris, pupil and lens abnormalities. Eye pressure is variably affected and can be low or high or start as one and rapidly change to the other. Chorioretinal changes in the form of vasculopathy are seen and ascribed to be secondary to anterior segment inflammation rather than due to the direct effect of CEI. Final outcome related to structure and function is determined by the injurious agent, duration of exposure, nature of treatment and the rapidity with which it is instituted. Prevention of further damage by profuse and prolonged eye wash, after ascertaining pH of both eyes, together with exploration and removal of all particulate matter, is the key. Other management principles include a complete and thorough assessment, control of inflammation, facilitation of healing and prevention and management of sequelae and complications. Intraocular pressure is often forgotten and must be assessed and managed. Management often requires a multidisciplinary approach.
Professor Henry Urich 1916-2015: A London neuropathologist and his Polish heritage.
Journal of medical biography, 2020

This is the story of a tumultuous life, lived with enthusiasm and considerable academic success, despite destruction of his cultural heritage in Poland, and loss of his family, by the cruelty of the invading Soviet and Nazi armies in 1939. As a newly qualified doctor from the Polish Medical School at the University of Edinburgh, he was parachuted into Arnhem with the Polish airborne forces, survived, educated himself in British ways and habits, and rapidly succeeded in the medical hierarchy to become an esteemed neuropathologist not only at The London Hospital, but internationally. His central European background provided him with the linguistic and multicultural skills to excel in this highly specialised area of medical science. He was one of the last of the classically trained neuropathologists.
Infant rats can acquire, but not retain contextual associations in object-in-context and contextual fear conditioning paradigms.
Developmental psychobiology, 2020

Context learning in postnatal day (PD) 16-18 rats has been taken by Revillo, Cotella, Paglini, and Arias (2015, Physiology & Behavior, 148, 6-21) to challenge the view that the ontogeny of contextual learning is related to the development of the hippocampal system (Rudy, 1993, Behavioral Neuroscience, 107(5), 887-891; Schiffino, Murawski, Rosen, & Stanton, 2011 Neurobiology of Learning and Memory, 95(2), 190-198). Whether context learning is "incidental" or "reinforcement-driven" may determine the ontogeny and neural systems involved (Rudy, 2009, Learning & Memory (Cold Spring Harbor, N.Y.), 16, 573-585). However, we have shown differential ontogeny of two different forms of incidental context learning, the context pre-exposure facilitation effect (CPFE; Jablonski, Schiffino, & Stanton, 2012, Developmental Psychobiology, 54(7), 714-722), which emerges between PD 17 and 21; and object-in-context recognition (OiC, Ramsaran, Westbrook, & Stanton, 2016, Developmental Psychobiology, 58(7), 883-895; Ramsaran, Sanders, & Stanton, 2016, Behavioural Brain Research, 298, 37-47), which is present on PD17. We investigated whether this task-dissociation reflects an encoding or a retention deficit, by varying the sample-to-testing intervals for both tasks. Experiment 1A found that PD17 rats were able to perform the OiC task after short (5 min) but not long (24 hr) sample-to-test intervals. Experiments 1B and 1C found that PD17 rats trained on the CPFE are able to acquire and express context-shock associations after short but not long retention intervals. These findings suggest that pre-weanling rats encode contexts but show poor consolidation or retrieval after longer retention intervals.
Mitochondrial alterations triggered by repeated exposure to fine (PM
Environment international, 2020

Nowadays ambient particulate matter (PM) levels still regularly exceed the guideline values established by World Health Organization in most urban areas. Numerous experimental studies have already demonstrated the airway toxicity of the fine fraction of PM (FP), mainly triggered by oxidative stress-induced airway inflammation. However, only few studies have actually paid close attention to the ultrafine fraction of PM (UFP), which is likely to be more easily internalized in cells and more biologically reactive. Mitochondria are major endogenous sources of reactive oxygen species (ROS) through oxidative metabolism, and coordinate many critical cellular signaling processes. Mitochondria have been often studied in the context of PM toxicity and generally associated with apoptosis activation. However, little is known about the underlying adaptation mechanisms that could occur following exposure at sub-apoptotic doses of ambient PM. Here, normal human bronchial epithelial BEAS-2B cells were acutely or repeatedly exposed to relatively low doses (5 µg.cm
The structure of non-human cognitive neuroscience: an epistemological critique.
Reviews in the neurosciences, 2019

Every scientific practice rests on implicit unrevised theoretical assumptions. Neuroscience, in particular, focuses on a very controversial object of study-the brain and is therefore prone to tacitly embrace philosophical positions in its everyday workings. It is thus, of utmost importance, to develop a critique of the structure of neuroscientific investigation so as to understand what the uncovered pillars of the field are, what pitfalls they may implicate and how we can correct them. In this paper, I gather the first critiques in animal cognitive neuroscience and hope to establish the first step in a continuous process of revision. By applying a conceptual division of neuroscience into cognitive, behavioral and neurobiological theories, I point out the main problems in articulating the three, based on actual scientific practice rather than purely theoretical reasoning. I conclude by proposing developments on behavioral theory and set an initial critique on assumptions on both cognitive and neurobiological theories.
Transient anosmia during acute phase electroconvulsive therapy: a report of 2 cases.
The journal of ECT, 2013

Treatment-resistant psychiatric illness poses a clinical challenge to psychiatrists in both inpatient and outpatient settings. Although electroconvulsive therapy is a relatively safe option for the treatment of these patients, initiation of this treatment requires a conscientious discussion of the risks and benefits of the procedure to obtain informed consent. The 2 cases presented here describe transient anosmia, a seldom reported but potentially significant adverse effect of electroconvulsive therapy.
Preserved emotional modulation of motor response time despite psychomotor slowing in young-old adults.
The International journal of neuroscience, 2011

Whereas aging affects cognitive and psychomotor processes negatively, the impact of aging on emotional processing is less clear. Using an "old-new" binary decision task, we ascertained the modulation of response latencies after presentation of neutral and emotional pictures in "young" (M = 27.1 years) and "young-old" adults with a mean age below 60 (M = 57.7 years). Stimuli varied on valence (pleasant, neutral, and unpleasant) and arousal (high and low) dimensions. Young-old adults had significantly longer reaction times. However, young and young-old adults showed the exact same pattern of response time modulation by emotional stimuli: Response latencies were longer for high-arousal than for low-arousal pictures and longer for negative than for positive or neutral stimuli. This result suggests that the specific effects of implicitly processed emotional valence and arousal information on behavioral response time are preserved in young-old adults despite significant age-related psychomotor decline.
EVALUATING SHORT-TERM EXPOSURE TO WI-FI SIGNALS ON STUDENTS' REACTION TIME, SHORT-TERM MEMORY AND REASONING ABILITY.
Radiation protection dosimetry, 2019

This study investigated the effect of short-term exposure to Wi-Fi signals on the cognitive functions of the mind. After obtaining permission from the local Ethics Committee of Shiraz University of Medical Sciences and approval by the Iranian Registry of Clinical Trials (IRCT2017041233398N1), 45 male and female students from Shiraz University of Medical Sciences volunteered to participate in this study. They were exposed to Wi-Fi signals in two sham and exposure sessions, each for 2 hours. After completion, they took part in reaction time, short-term memory, and reasoning ability tests. After scoring, the data were analysed by SPSS software. In addition, the electric field strength and power density were calculated. The results showed no statistically significant differences between the mean scores of reaction time, short-term memory, and reasoning ability in sham and exposure. Also, the obtained values from the electric field strength and power density (E = 4.1 Vm-1, P = 0.446 Wm-2) were lower than that of threshold values by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Our results can greatly reduce concerns regarding the effects of short-term exposure to Wi-Fi waves on cognitive functions.
Rare occurrence of IDH2 mutation in adolescent oligodendroglioma with 1p/19q co-deletion: a case report.
Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 2020

Adolescent and young adult gliomas are recently being studied as a distinct group and molecular alterations of oligodendroglioma in this group are not well defined. Few studies conducted on adolescent oligodendroglioma so far have found low frequencies of IDH mutations and 1p/19q co-deletion, which are the hallmark genetic alterations seen in adult oligodendroglioma. In this case report, we demonstrate presence of rare IDH2 mutation and 1p/19q co-deletion in an adolescent oligodendroglioma.
Caffeine for apnea of prematurity and brain development at 11 years of age.
Annals of clinical and translational neurology, 2018

Caffeine therapy for apnea of prematurity has been reported to improve brain white matter microstructure at term-equivalent age, but its long-term effects are unknown. This study aimed to investigate whether caffeine affects (1) brain structure at 11 years of age, and (2) brain development from term-equivalent age to 11 years of age, compared with placebo.
Assessment of neuroinflammation in the aging hippocampus using large-molecule microdialysis: Sex differences and role of purinergic receptors.
Brain, behavior, and immunity, 2021

Aging is associated with an enhanced neuroinflammatory response to acute immune challenge, often termed "inflammaging." However, there are conflicting reports about whether baseline levels of inflammatory markers are elevated under ambient conditions in the aging brain, or whether such changes are observed predominantly in response to acute challenge. The present studies utilized two distinct approaches to assess inflammatory markers in young and aging Fischer 344 rats. Experiment 1 examined total tissue content of inflammatory markers from hippocampus of adult (3 month), middle-aged (12 month), and aging (18 month) male Fischer (F) 344 rats using multiplex analysis (23-plex). Though trends emerged for several cytokines, no significant differences in basal tissue content were observed across the 3 ages examined. Experiment 2 measured extracellular concentrations of inflammatory factors in the hippocampus from adult (3 month) and aging (18 month) males and females using large-molecule in vivo microdialysis. Although few significant aging-related changes were observed, robust sex differences were observed in extracellular concentrations of CCL3, CCL20, and IL-1α. Experiment 2 also evaluated the involvement of the P2X7 purinergic receptor in neuroinflammation using reverse dialysis of the selective agonist BzATP. BzATP produced an increase in IL-1α and IL-1β release and rapidly suppressed the release of CXCL1, CCL2, CCL3, CCL20, and IL-6. Other noteworthy sex by aging trends were observed in CCL3, IL-1β, and IL-6. Together, these findings provide important new insight into late-aging and sex differences in neuroinflammation, and their regulation by the P2X7 receptor.

Remarks on neurocybernetics and its links to computing science. To the memory of Prof. Luigi M. Ricciardi.
Bio Systems, 2013

This paper explores the origins and content of neurocybernetics and its links to artificial intelligence, computer science and knowledge engineering. Starting with three remarkable pieces of work, we center attention on a number of events that initiated and developed basic topics that are still nowadays a matter of research and inquire, from goal directed activity theories to circular causality and to reverberations and learning. Within this context, we pay tribute to the memory of Prof. Ricciardi documenting the importance of his contributions in the mathematics of brain, neural nets and neurophysiological models, computational simulations and techniques.
What do people with dementia and their carers want to know about neuroimaging for dementia?
Dementia (London, England), 2017

Neuroimaging forms an important part of dementia diagnosis. Provision of information on neuroimaging to people with dementia and their carers may aid understanding of the pathological, physiological and psychosocial changes of the disease, and increase understanding of symptoms. This qualitative study aimed to investigate participants' knowledge of the dementia diagnosis pathway, their understanding of neuroimaging and its use in diagnosis, and to determine content requirements for a website providing neuroimaging information. Structured interviews and a focus group were conducted with carers and people with dementia. The findings demonstrate an unmet need for information on neuroimaging both before and after the examination. Carers were keen to know about neuroimaging at a practical and technical level to help avoid diagnosis denial. People with dementia requested greater information, but with a caveat to avoid overwhelming detail, and were less likely to favour an Internet resource.
