Encyclopedia > Visual area V2

Visual area V2 is the second major area in the occipital lobe of the cerebral cortex. It receives strong feedforward connections from Primary visual cortex (V1) and sends strong connections to Visual area V4 and Visual area MT. It also sends strong feedback connections to the Primary visual cortex. The occipital lobes are the visual processing center of mammalian brains. ... Location of the Cerebral cortex Slice of the Cerebral cortex, ca. ... Feed-forward is a term describing a kind of system which reacts to changes in its environment, usually to maintain some desired state of the system. ... Brodmann area 17 (primary visual cortex) is shown in red in this image which also shows area 18 (orange) and 19 (yellow) The primary visual cortex (usually called V1) is the most well-studied visual area in the brain. ... Visual area V4 is an one of the visual areas in the extrastriate visual cortex of the macaque monkey. ... In cybernetics and control theory, feedback is a process whereby some proportion or in general, function, of the output signal of a system is passed (fed back) to the input. ... Brodmann area 17 (primary visual cortex) is shown in red in this image which also shows area 18 (orange) and 19 (yellow) The primary visual cortex (usually called V1) is the most well-studied visual area in the brain. ...


Anatomically, V2 is split into four quadrants, a dorsal and ventral representation in the left and the right hemispheres. Together these four regions provide a complete map of the visual world. Functionally, V2 has many properties in common with Primary visual cortex. Cells are tuned to simple properties such as orientation, spatial frequency, and color. The contents of this page have been moved to http://en. ... In zootomy, several terms are used to describe the location of organs and other structures in the body of bilateral animals. ... Á cerebrum is a part of the brain. ... Brodmann area 17 (primary visual cortex) is shown in red in this image which also shows area 18 (orange) and 19 (yellow) The primary visual cortex (usually called V1) is the most well-studied visual area in the brain. ...


Recent research has shown that V2 cells are tuned to the orientation of illusory contours, shows a small amount of attentional modulation (more than V1, less than V4), are tuned for moderately complex patterns, and may be driven by multiple orientations at different subregions within a single receptive field.

Visual area V2 is the second major area in the occipital lobe of the cerebral cortex.
Anatomically, V2 is split into four quadrants, a dorsal and ventral representation in the left and the right hemispheres.
Recent research has shown that V2 cells are tuned to the orientation of illusory contours, shows a small amount of attentional modulation (more than V1, less than V4), are tuned for moderately complex patterns, and may be driven by multiple orientations at different subregions within a single receptive field.
Visual area V4 - Wikipedia, the free encyclopedia (406 words)
Visual area V4 is an one of the visual areas in the extrastriate visual cortex of the macaque monkey.
V4 is the third cortical area in the ventral stream, receiving strong feedforward input from visual area V2, and sending strong connections to the posterior inferotemporal cortex (PIT).
Visual area V4 is not tuned for complex objects such as faces, as areas in the inferotemporal cortex are.
