Shape Perception Simultaneously Up- and Downregulates Neural Activity in the Primary Visual Cortex

Abstract

An essential part of visual perception is the grouping of local elements (such as edges and lines) into coherent shapes. Previous studies have shown that this grouping process modulates neural activity in the primary visual cortex (V1) that is signaling the local elements [1-4]. However, the nature of this modulation is controversial. Some studies find that… (More)
