In mammals, a larger number of neurons in V1 are devoted to cardinal (horizontal and
vertical) orientations than to oblique orientations. However, electrophysiological results from …

Neurons in primate V4 exhibit various types of selectivity for contour shapes, including
curves, angles, and simple shapes. How are these neurons organized in V4 remains …

An important aspect of visual object recognition is the ability to perceive object shape. Two
basic components of complex shapes are straight and curved contours. A large body of …

A selective deficit in processing the global (overall) motion, but not form, of spatially
extensive objects in the visual scene is frequently associated with several …

Spatial frequency (SF) is an important attribute in the visual scene and is a defining feature
of visual processing channels. However, there remain many unsolved questions about how …

The cerebral cortices of human and nonhuman primate brains are characterized by
submillimeter functional domains. However, little is known about the connections of single …

The orientation map is one of the most well-studied functional maps of the visual cortex.
However, results from the literature are of different qualities. Clear boundaries among …

In this opinion essay, I address the perennial binding problem, that is to say of how
independently processed visual attributes such as form, colour and motion are brought …

Traditional electrical stimulation of brain tissue typically affects relatively large volumes of
tissue spanning multiple millimeters. This low spatial resolution stimulation results in …

In the primate visual system, direction-selective (DS) neurons are critical for visual motion
perception. While DS neurons in the dorsal visual pathway have been well characterized …
