Task-Irrelevant Visual Forms Facilitate Covert and Overt Spatial Selection
Authors: Bogadhi Amarender R. , Buonocore Antimo , Hafed Ziad M. 
Published: October 2020

Covert and overt spatial selection behaviors are guided by both visual saliency maps derived from early visual features as well as priority maps reflecting high-level cognitive factors. However, whether mid-level perceptual processes associated with visual form recognition contribute to covert and overt spatial selection behaviors remains unclear. We hypothesized that if peripheral visual forms contribute to spatial selection behaviors, then they should do so even when the visual forms are task-irrelevant. We tested this hypothesis in male and female human subjects as well as in male macaque monkeys performing a visual detection task. In this task, subjects reported the detection of a suprathreshold target spot presented on top of one of two peripheral images, and they did so with either a speeded manual button press (humans) or a speeded saccadic eye movement response (humans and monkeys). Crucially, the two images, one with a visual form and the other with a partially phase-scrambled visual form, were completely irrelevant to the task. In both manual (covert) and oculomotor (overt) response modalities, and in both humans and monkeys, response times were faster when the target was congruent with a visual form than when it was incongruent. Importantly, incongruent targets were associated with almost all errors, suggesting that forms automatically captured selection behaviors. These findings demonstrate that mid-level perceptual processes associated with visual form recognition contribute to covert and overt spatial selection. This indicates that neural circuits associated with target selection, such as the superior colliculus, may have privileged access to visual form information.SIGNIFICANCE STATEMENTSpatial selection of visual information either with (overt) or without (covert) foveating eye movements is critical to primate behavior. However, it is still not clear whether spatial maps in sensorimotor regions known to guide overt and covert spatial selection are influenced by peripheral visual forms. We probed the ability of humans and monkeys to perform overt and covert target selection in the presence of spatially congruent or incongruent visual forms. Even when completely task-irrelevant, images of visual objects had a dramatic effect on target selection, acting much like spatial cues used in spatial attention tasks. Our results demonstrate that traditional brain circuits for orienting behaviors, such as the superior colliculus, likely have privileged access to visual object representations.

AbstrakBakteri endofit hidup dalam suatu tanaman tanpa menyebabkan gangguan bagi tanaman yang berperan penting dalam menstimulasi pertumbuhan tanaman, yaitu dengan memproduksi fitohormon seperti asam absisat, asam indol asetat, dan sitokinin. Penelitian ini bertujuan untuk mengisolasi, menyeleksi, dan mengidentifikasi bakteri endofit yang terdapat pada daun, batang, dan akar tanaman jeruk nipis (Citrus aurantifolia). Isolat bakteri endofit diseleksi berdasarkan kemampuannya dalam menghasilkan asam indol asetat (AIA). Isolat bakteri endofit ditumbuhkan pada media nutrient broth (NB) yang ditambah dengan L-triptofan. Konsentrasi AIA dihitung dengan penambahan reagen salkowski dan diukur menggunakan spektrofotometer pada panjang gelombang 530 nm. Identifikasi bakteri endofit dilakukan dengan analisis uji biokimia. Isolat bakteri endofit yang berhasil diisolasi sebanyak 12 isolat, yaitu 4 isolat dari daun, 4 isolat dari batang, dan 4 isolat dari akar. Hasil pengamatan pada uji AIA menunjukkan bahwa semua isolat bakteri endofit dapat menghasilkan hormon AIA. Isolat yang menghasilkan konsentrasi hormon AIA tertinggi adalah isolat B2 (6,51 ppm). Isolat bakteri yang berhasil diidentifikasi berasal dari genus Enterobacter, Bacillus, Pseudomonas, dan Staphylococcus. Bakteri endofit yang dapat menghasilkan AIA berpotensi dikembangkan sebagai biofertilizer untuk meningkatkan produktivitas tanaman. Abstract Endophytic bacteria live inside plants without causing disruption to plants and play an important role in stimulating plant growth. This study aims to isolate endophytic bacteria from lime plant (Citrus aurantifolia) and characterize its ability to produce indole acetic acid (IAA). Bacterial isolates were grown on media supplemented with L-tryptophan as IAA precursor. The bacterial supernatant was mixed with salkowski reagents and then measured using a spectrophotometer at 530 nm. Bacterial identification was carried out using biochemical characteristic analysis. A total of 12 endophytic bacterial isolates were successfully isolated from leaves, stem and roots of plants. Quantitative test results showed that all isolates can produce IAA. The highest concentration of IAA was produced by B2 (6.51 ppm). Biochemical analysis indicated that the isolates were from the genus Enterobacter, Bacillus, Pseudomonas and Staphylococcus. Endhophytic bacteria that can produce IAA have the potential to be developed as biofertilizers to increase crop productivity.

Published: October 2020

Background: Primitive neuroectodermal tumors (PNETs) are malignant soft tissue tumors of neuroepithelial origin with an aggressive nature and associated with early disseminated metastasis, resulting in poor prognosis. It occurs more frequently in men of age < 35 years, and in several parts of the body, such as pulmonary tract, nasal cavity, paranasal sinuses, and/or neck. Orbital location is infrequent and has been reported in less than 20 cases in the English literature so far.
Case presentation: In this paper, we report our experience with a 77 year-old man who was referred with a 2.8 cm mass in the superior-anterior quadrant of his left eye for 2 weeks prior to admission, as well as having a 15-kg weight loss during the past six months. The patient developed rapidly progressive visual loss, decreased eye movements, and conjunctivitis within a week. Thus, the patient underwent orbitotomy and the results of histological examination and immunohistochemistry showed an orbital PNET. Metastasis to frontal sinuses and ethmoid sinuses were also discovered. The patient passed away before referral to the oncologist.
Conclusion: This report confirms the highly aggressive nature of PNET and reports its rare occurrence in orbital cavity.

AbstractEquine grass sickness (also known as dysautonomia) is a life-threatening polyneuropathic disease affecting horses with approx. 80% mortality. Since its first description over a century ago, several factors, such as the phenotype, intestinal microbiome, environment, management and climate, have been supposed to be associated with the increased risk of dysautonomia. In this retrospective study, we examined the possible involvement of genetic factors. Medical and pedigree datasets regarding 1,233 horses with 49 affected animals born during a 23-year period were used in the analysis. Among the descendants of some stallions, the proportion of animals diagnosed with dysautonomia was unexpectedly high. Among males, the odds of dysautonomia were found to be higher, albeit not significantly, than among females. Significant familial clustering (genealogical index of familiality,P= 0.001) was observed among the affected animals. Further subgroups were identified with significant (P< 0.001) aggregation among close relatives using kinship-based methods. Our analysis, along with the slightly higher disease frequency in males, suggests that dysautonomia may have a genetic causal factor with an X-linked recessive inheritance pattern. This is the first study providing ancestry data and suggesting a heritable component in the likely multifactorial aetiology of the disease.
Complete genome analysis confirms that the pygmy marmoset adenovirus is a variant of the skunk adenovirus 1 – Short communication

Published: October 2020

AbstractThe complete genomic sequence along with phylogenetic analyses of an adenovirus (AdV), isolated from a dead captive pygmy marmoset (Callithrix pygmaea) from a Hungarian zoo is reported. Earlier, based on the phylogenetic analysis of the sequence of a PCR-amplified fragment from the DNA polymerase gene, the pygmy marmoset AdV (PMAdV) has been reported to cluster closest to certain chiropteran AdVs. In the following years similar AdVs were discovered in additional mammalian hosts, including a skunk (Mephitis mephitis), African pygmy hedgehogs (Atelerix albiventris), North American porcupines (Erethizon dorsatum) and grey fox (Urocyon cinereoargenteus). After the full genome analysis of the skunk adenovirus (SkAdV-1), a novel species Skunk mastadenovirus A (SkAdV-A) has been established. The AdVs, originating from the African pygmy hedgehogs, have been found to belong to virus species SkAdV-A. Partial gene sequences from the porcupine AdVs have also implied their very close genetic relatedness to SkAdV-A. The complete genomic sequence of PMAdV, examined in this study, was found to share 99.83% nucleotide identity with SkAdV-1, thus unequivocally represents a genomic variant of SkAdV-1. The observation that viruses classifiable as SkAdV-A are able to infect and cause diseases in several, distantly related mammals seems to deserve further studies to elucidate the infection biology of this intriguing AdV.

Published: October 2020

AbstractThis study was designed to evaluate and compare the optimal sites for intra-articular (IA) injection into the digits of buffalo by discrimination of the injection criteria. Forty-eight cadaveric hind digits of adult buffalos and nine live ones were assigned for three trial investigations. In the first division, eighteen sound cadaveric limbs were used to describe the anatomical features of the hind digit. In the second division, thirty cadaveric limbs (ten for each approach) were injected with an equal volume of iopamidol through relevant joint pouches to compare the dorsal, lateral and plantar IA approaches for each joint. The former technique was applied to nine live, healthy adult buffaloes to evaluate the accuracy of IA injection of the hind digitin vivo. Injection criteria were assessed, scored and statistically compared among the three approaches. The summation of injection criteria scores showed a significant increase (P< 0.05) in the dorsal and lateral approaches for IA injection of the fetlock, pastern and coffin joints in the buffalo digit compared to the plantar one. However, median and range of injection criteria scores between the dorsal and lateral approaches were slightly less significant. In conclusion, the present study established a reference for IA injection of the buffalo digit that could aid the diagnosis and treatment of digit-related lameness.

Published: October 2020

AbstractThe aim of the study is to give an insight into the evaluation of the program “Mentor Migration SALAM – Spielen Austauschen-Lernen-Achtsam-Miteinander” (Playing-Sharing-Learning-Attentively-Together). Students striving for a teaching degree or studying Social education at the University of Education Freiburg, mentor a child from a migrant or a refugee family for a period of 9 months. Some of the evaluation results are presented here. Based on different instruments like a questionnaire, open questions, interviews, reports, and minutes of the supervision meetings the mostly qualitative data are analysed and categorized. The article focuses on the impacts on the students: They gain a better awareness for intercultural encounters, and get insights into milieus they usually would not have. So especially the competences ‘Coping with Difference’ and ‘Professional pedagogical Skills’ will be investigated. The Intercultural Competence Model of Deardorff gives the theoretical background.
