The extrastriate cortex is the region of the occipital cortex of the mammalian brain located next to the primary visual cortex. Primary visual cortex (V1) is also named striate cortex because of its striped appearance in the microscope.
EXTRASTRIATE CORTEX. Anatomical and functional discoveries since the early 1970s in the monkey and human brain have caused a radical revision of theories of how the visual system is organized in the extrastriate cortex, the visually responsive cortex outside striate area 17 or V1. The most important of these discoveries is that many cortical ...
Extrastriate visual cortex. A fairly congruent picture has emerged of the involvement of extrastriate visual areas, which lie beyond V1 in the visual pathway, in multistable perception.
Based on the anatomical connections between visual areas, differences in electrophysiological response properties, and the effects of cortical lesions, a consensus has emerged that extrastriate cortical areas are organized into two largely separate systems that eventually feed information into cortical association areas in the temporal and parie...
Extrastriate Visual Cortex. The frontal and extrastriate visual cortexes transmit information about the motion of both the target and the eyes to the dorsolateral pontine nuclei, thence to the paraflocculus, flocculus, and dorsal vermis, and then via the vestibular and fastigial nuclei to the ocular motor nerve nuclei III, IV, and VI.
Extrastriate visual cortex refers to a large number of well-defined cortical areas and less well defined cortical zones that are located anterior to primary visual cortex (area V1 or striate cortex) which are implicated in visual function on the basis of their physiology, cortical connections, and/or behavioral contributions to visual perception.
The extrastriate cortex is involved in the analysis of specific attributes of visual stimuli (e.g., color, form, movement, and binocular disparity). Visual information is progressively decomposed as it is channeled through processing streams.
The extrastriate cortex is the part of the visual cortex that is located next to the striate cortex. The extrastriate cortex consists of multiple brain areas involved in processing specific ...
Extrastriate visual cortex comprises a mosaic of anatomically and physiologically distinct areas which occupy a broad belt of cortex outside the striate area (area 17, or VI). These areas receive their major visual input directly or indirectly from striate cortex and...
These areas are known collectively as “extrastriate visual cortex”. Mapping the boundaries, organization, and projections of these visual areas is a difficult challenge, in part because the primate cerebral cortex is highly folded into sulci and gyri.
