A computational study of how orientation bias in the lateral geniculate nucleus can give rise to orientation selectivity in primary visual cortex

open access: yesFrontiers in Systems Neuroscience, 2011
Controversy remains about how orientation selectivity emerges in simple cells of the mammalian primary visual cortex. In this paper, we present a computational model of how the orientation-biased responses of cells in lateral geniculate nucleus can ...

Functional anatomy of macaque striate cortex. III. Color [PDF]

open access: yesThe Journal of Neuroscience, 1988
Using spatially diffuse stimuli (or sinusoidal gratings of very low spatial frequency), levels of 14C-2-deoxy-d-glucose (DG) uptake produced by color-varying stimuli are much greater than those produced by luminance-varying stimuli in macaque striate cortex.

Vat photopolymerization‐based bioprinting: Shaping next‐generation tissues with light

open access: yesInterdisciplinary Medicine, EarlyView.
Vat photopolymerization‐based bioprinting is revolutionizing biofabrication by enabling high‐precision construction of biological structures. This review systematically examines photopolymerization mechanisms and variants in printing techniques, discusses design principles and composition of bio‐inks, and highlights recent progress toward next ...

Emergent Orientation Selectivity from Random Networks in Mouse Visual Cortex [PDF]

open access: yes, 2018
The connectivity principles underlying the emergence of orientation selectivity in primary visual cortex (V1) of mammals lacking an orientation map (such as rodents and lagomorphs) are poorly understood.

Lions as Bone Accumulators? Exploring Multi‐Predator Contributions to the Olduvai Carnivore Site (OCS) (Tanzania) Through AI and Metric Analyses

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

open access: yesPhytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Circuit Mechanisms Governing Local vs. Global Motion Processing in Mouse Visual Cortex

open access: yesFrontiers in Neural Circuits, 2017
A withstanding question in neuroscience is how neural circuits encode representations and perceptions of the external world. A particularly well-defined visual computation is the representation of global object motion by pattern direction-selective (PDS)

Multi-area visuotopic map complexes in macaque striate and extra-striate cortex

open access: yesVision Research, 2006
We propose that a simple, closed-form mathematical expression-the Wedge-Dipole mapping-provides a concise approximation to the full-field, two-dimensional topographic structure of macaque V1, V2, and V3. A single map function, which we term a map complex, acts as a simultaneous descriptor of all three areas.

Associations of Vestibular Disorders With Risk of All‐Cause and Cause‐Specific Dementia: A Longitudinal Cohort Study in UK Biobank

open access: yesSensory Neuroscience, EarlyView.
ABSTRACT To explore associations of vestibular disorders with all‐cause and cause‐specific dementia and underlying biological mechanisms/neuroimaging changes. A population‐based cohort study of 406,348 UK Biobank participants was conducted. Inverse probability of treatment weighting (IPTW) balanced baseline covariates, and Cox proportional hazards ...
