[HTML][HTML] Polar angle asymmetries in visual perception and neural architecture
Human visual performance changes with visual field location. It is best at the center of gaze
and declines with eccentricity, and also varies markedly with polar angle. These perceptual …

Cortical magnification eliminates differences in contrast sensitivity across but not around the visual field
Human visual performance changes dramatically both across (eccentricity) and around
(polar angle) the visual field. Performance is better at the fovea, decreases with eccentricity …

Presaccadic attention depends on eye movement direction and is related to V1 cortical magnification
NM Hanning, MM Himmelberg… - Journal of …, 2024 - Soc Neuroscience
With every saccadic eye movement, humans bring new information into their fovea to be
processed with high visual acuity. Notably, perception is enhanced already before a relevant …

When periphery rules: Enhanced sampling weights of the visual periphery in crowding across dimensions
A Yashar, M Carrasco - Psychonomic Bulletin & Review, 2024 - Springer
Crowding, our inability to identify a feature or object–the target–due to its proximity to
adjacent features or objects–flankers–exhibits a notable inner-outer asymmetry. This …

Retinal waves in adaptive rewiring networks orchestrate convergence and divergence in the visual system
R Luna, J Li, R Bauer, C van Leeuwen - Network Neuroscience, 2024 - direct.mit.edu
Spontaneous retinal wave activity shaping the visual system is a complex
neurodevelopmental phenomenon. Retinal ganglion cells are the hubs through which …

How the window of visibility varies around polar angle
Contrast sensitivity, the amount of contrast required to discriminate an object, depends on
spatial frequency (SF). The contrast sensitivity function (CSF) peaks at intermediate SFs and …

Retinotopic Foveated Rendering
Foveated rendering (FR) improves the rendering performance of virtual reality (VR) by
allocating fewer computational loads in the peripheral field of view (FOV). Existing FR …

Cortical layering disrupts multi-electrode current steering
Objective. Blindness affects approximately 40 million people worldwide and has inspired the
development of cortical visual prostheses for restoring sight. Cortical visual prostheses …

Spatial processing of limbs reveals the center-periphery bias in high level visual cortex follows a nonlinear topography
E Daniel Hertz, JK Yao, S Gregorek, PM Hoyos… - bioRxiv, 2023 - biorxiv.org
Human visual cortex contains regions selectively involved in perceiving and recognizing
ecologically important visual stimuli such as people and places. Located in the ventral …

Shared spatial selectivity in early visual cortex and face-selective brain regions
Face recognition is widely considered to be ″special ″, involving dedicated brain regions
with unique patterns of selectivity. This contrasts with increasing evidence for common …
