Time course of visual perception: coarse-to-fine processing and beyond
J Hegdé - Progress in neurobiology, 2008 - Elsevier
Our perception of a visual scene changes rapidly in time, even when the scene itself does

Neuronal selectivity and local map structure in visual cortex
The organization of primary visual cortex (V1) into functional maps makes individual cells
operate in a variety of contexts. For instance, some neurons lie in regions of fairly …

Receptive field properties of neurons in the early visual cortex revealed by local spectral reverse correlation
We introduce a novel class of white-noise analyses, named local spectral reverse
correlation (LSRC), which is capable of revealing various aspects of visual receptive field …

Neural basis for stereopsis from second-order contrast cues
Humans and animals use visual cues such as brightness and color boundaries to identify
objects and navigate through environments. However, even when these cues are not …

Dynamic spatial processing originates in early visual pathways
A variety of studies in the visual system demonstrate that coarse spatial features are
processed before those of fine detail. This aspect of visual processing is assumed to …

Surround suppression of V1 neurons mediates orientation-based representation of high-order visual features
Neurons with surround suppression have been implicated in processing high-order visual
features such as contrast-or texture-defined boundaries and subjective contours. However …
