cortex

 [kor´teks] (pl. cor´tices) (L.)
the outer layer of an organ or other structure, as distinguished from its inner substance or medulla. adj., adj cor´tical.
adrenal cortex (cortex of adrenal gland) the outer, firm layer comprising the larger part of the adrenal gland; it secretes mineralocorticoids, androgens, and glucocorticoids.
cerebellar cortex the superficial gray matter of the cerebellum.
cerebral cortex (cortex cerebra´lis) the convoluted layer of gray matter covering each cerebral hemisphere. See also brain.
renal cortex the granular outer layer of the kidney, composed mainly of glomeruli and convoluted tubules, extending in columns between the pyramids that constitute the renal medulla.
striate cortex part of the occipital lobe that receives the fibers of the optic radiation and serves as the primary receiving area for vision. Called also first visual area.
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]
O. and C. Vogt term for the larger part of the mammalian cerebral cortex, distinguished from the allocortex by being composed of a larger number of nerve cells arranged in six layers.
See also: cerebral cortex.

neocortex

/neo·cor·tex/ (-kor´teks) the newer, six-layered portion of the cerebral cortex, showing the most highly evolved stratification and organization. Cf. archicortex and paleocortex.

neocortex

(nē′ō-kôr′tĕks′)
n. pl. neocor·tices (-tĭ-sēz′) or neocor·texes
The dorsal region of the cerebral cortex, especially large in primates, thought to have evolved more recently than other parts of the brain. Also called neopallium.

ne′o·cor′ti·cal (-tĭ-kəl) adj.

neocortex

[-kôr′teks]
Etymology: Gk, neos, new; L, cortex, bark
the most recently evolved part of the brain. In humans the neocortex includes all of the cerebral cortex except for the hippocampal and piriform areas.

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.
[G. neos, new, + L. cortex, bark]

neocortex (nēˈ·ō·kor′·teks),

n the outer surface of the cerebrum that is responsible for higher functions reason, memory, cognition in human beings.

The cortico-thalamic projections which complete a closed circuit between the thalamus and the neocortex present an opportunity for the application of computational modeling and thus it may contribute to the effort to explain the in vivo function of these projections (Hillenbrand & Hemmen, 2002; Alitto & Usrey, 2003).
