Representation of stereoscopic edges in monkey visual cortex
Form perception in random-dot stereograms is based on information that resides in the correlation between the two images, but is not present in either image alone. We have studied the coding of stereoscopic figures in the neural activity of areas V1 and V2 of alert behaving monkeys. While cells in V1 generally responded according to the disparity of the surface at the receptive field, we found ...
متن کاملRepresentation of central visual fields in prestriate cortex of monkey.
In 1941, Talbot and Marshall 16 reported the manner in which the visual fields are represented in striate cortex of monkey. From this study, later confirmed by Daniel and Whitteridge 6, it appeared that the vertical meridian of the lower and upper visual fields is represented at the striate prestriate boundary behind the lunate and above the inferior occipital sulci respectively with the foveal...
متن کاملStereoscopic mechanisms in monkey visual cortex: binocular correlation and disparity selectivity.
The neural signals in visual cortex associated with positional disparity and contrast texture correlation of binocular images are the subject of this study. We have analyzed the effects of stereoscopically presented luminous bars and of dynamic random-dot patterns on the activity of single neurons in cortical visual areas V1, V2, and V3-V3A of the alert, visually trained rhesus macaque. The int...
متن کاملfMRI of Monkey Visual Cortex
While functional magnetic resonance imaging (fMRI) is now used widely for demonstrating neural activity-related signals associated with perceptual, motor, and cognitive processes in humans, to date this technique has not been developed for use with nonhuman primates. fMRI in monkeys offers a potentially valuable experimental approach for investigating brain function, which will complement and a...
متن کاملThree-Dimensional Shape Representation in Monkey Cortex
Using fMRI in anesthetized monkeys, this study investigates how the primate visual system constructs representations of three-dimensional (3D) shape from a variety of cues. Computer-generated 3D objects defined by shading, random dots, texture elements, or silhouettes were presented either statically or dynamically (rotating). Results suggest that 3D shape representations are highly localized, ...
