Sustained activity in topographic areas of human posterior parietal cortex during memory-guided saccades.
TL;DR: It is shown that these areas exhibit sustained delay-period activity, a critical physiological signature of areas in macaque parietal cortex, and all three parietal regions showed comparable delay- period response amplitudes, with a trend toward larger responses from V7 to IPS1 and IPS2.
Journal ArticleDOI
Cross-orientation suppression in human visual cortex
G.J. Brouwer,David J. Heeger +1 more
TL;DR: The normalization model can explain cross-orientation suppression in human visual cortex and can be applied broadly to infer the responses of several subpopulations of neurons in the human brain that span particular stimulus or feature spaces, and characterize their interactions.
Journal ArticleDOI
Hierarchy of cortical responses underlying binocular rivalry.
TL;DR: Results from experiments in which observers' attention was diverted from the rival stimuli imply that competition between two rival stimuli involves neural circuits in V1, and attention is crucial for the consequences of this neural competition to advance to higher visual areas and promote perceptual waves.
Journal ArticleDOI
Top-down flow of visual spatial attention signals from parietal to occipital cortex.
TL;DR: This work test the hypothesis that topographically organized posterior parietal cortical areas IPS1 and IPS2 transmit top-down spatial attention signals to early visual cortex and measures functional connectivity among cortical areas V1, V2, V3, V4, V5, V6, and IPS1 during sustained visual spatial attention to measure coherency.
Proceedings ArticleDOI
Motion without movement
TL;DR: A technique for displaying patterns that appear to move continuously without changing their positions is described, using a quadrature pair of oriented filters to vary the local phase, giving the sensation of motion.
