visual cortex the area of the occipital lobe of the cerebral cortex concerned with vision; the striate cortex is also called the first visual area, and the adjacent second and third visual areas serve as its association areas.

i·so·cor·tex

(ī'sō-kōr'teks), [TA]

ne·o·cor·tex

(nē'ō-kōr'teks) [TA]
The newest part of the cerebral cortex, involved in higher functions such as sensory perception, generation of motor commands, spatial reasoning, conscious thought, and in humans, language; consists of gray matter surrounding the deeper white matter of the cerebrum; accounts for approximately 23% of the neurons in brains of human males and 19% of the neurons in human females.
Synonym(s): neopallium.
