[HTML][HTML] Polar angle asymmetries in visual perception and neural architecture

MM Himmelberg, J Winawer, M Carrasco - Trends in Neurosciences, 2023 - cell.com
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

M Jigo, D Tavdy, MM Himmelberg, M Carrasco - elife, 2023 - elifesciences.org
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

Y Kwak, ZL Lu, M Carrasco - Journal of Vision, 2024 - jov.arvojournals.org
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

Y Zhang, K You, X Hu, H Zhou… - … Virtual Reality and …, 2024 - ieeexplore.ieee.org
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

SJ Meikle, MA Hagan, NSC Price… - Journal of Neural …, 2023 - iopscience.iop.org
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

AY Morsi, HT Chow-Wing-Bom, DS Schwarzkopf… - bioRxiv, 2024 - biorxiv.org
Face recognition is widely considered to be ″special ″, involving dedicated brain regions
with unique patterns of selectivity. This contrasts with increasing evidence for common …
