Synaptic transmission from excitatory nerve cells in the mammalian brain is largely mediated
by AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid)-type glutamate receptors …

This review focuses on low and intermediate stages of contour shape processing. It is split
into two main sections,'Contour Detection'and 'Shape Discrimination and Representation' …

Visuo-perceptual processing in autism is characterized by intact or enhanced performance
on static spatial tasks and inferior performance on dynamic tasks, suggesting a deficit of …

Visual shape recognition in primates depends on a multi-stage pathway running from
primary visual cortex (V1) to inferotemporal cortex (IT). The mechanisms by which local …

The ventral pathway in visual cortex is responsible for the perception of shape. Area V4 is an
important intermediate stage in this pathway, and provides the major input to the final stages …

Object perception depends on shape processing in the ventral visual pathway, which in
monkeys culminates in inferotemporal cortex (IT). Here we provide a description of …

One of the more stunning examples of the resourcefulness of human vision is the ability to
see 'biological motion', which was first shown with an adaptation of earlier cinematic work …

Detection thresholds for radial deformations of circular contours were measured using a
range of radii and contour peak spatial frequencies. For radial frequencies above two cycles …

Psychophysical studies suggest that figure–ground organization is a largely autonomous
process that guides—and thus precedes—allocation of attention and object recognition. The …

Glass (Nature 1969; 223: 578–580) patterns are random dot stimuli that generate a percept
of global structure. To study the mechanisms underlying this global form perception …
