The visual cortex of the brain is the area of the cerebral cortex that processes visual information.It is located in the occipital lobe.Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.
The lateral intraparietal cortex (area LIP) is found in the intraparietal sulcus of the brain. [1] This area is most likely involved in eye movement, as electrical stimulation evokes saccades (quick movements) of the eyes. It is also thought to contribute to working memory associated with guiding eye movement, examined using a delayed saccade ...
The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional , connective , and developmental regions are listed in parentheses where appropriate. Hindbrain (rhombencephalon)
These loops are retinotopical, meaning that regions getting visual input are responsible for the same region in the visual field as the area of the cortex that projects to the claustrum. The visual claustrum is a single map of the contralateral visual hemifield, receiving information based on motion in the visual field's periphery and has no ...
Both the left and right hemispheres of the brain have a lateral geniculate nucleus, named after its resemblance to a bent knee (genu is Latin for "knee"). In humans as well as in many other primates , the LGN has layers of magnocellular cells and parvocellular cells that are interleaved with layers of koniocellular cells.
Brodmann area 8. The frontal eye fields (FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, [1] of the primate brain.In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus, consisting of a frontal and parietal portion. [2]
In terms of Brodmann areas, the extrastriate cortex comprises Brodmann area 18 and Brodmann area 19, while the striate cortex comprises Brodmann area 17. [3]In primates, the extrastriate cortex includes visual area V3, visual area V4, and visual area MT (sometimes called V5), [3] while V1 corresponds to the striate cortex, and V2 to the prestriate cortex.
These areas receive input from koniocellular cells in the dorsal lateral geniculate nucleus dLGN and output to the thin stripes of area V2. Interblobs are areas between blobs that receive the same input, but are sensitive to orientation instead of color. They output to the pale and thick stripes of area V2. Blobs are on the koniocellular pathway.
