| heterotypic cortex | O. Vogt's term denoting several regions of the cerebral cortex, in particular the olfactory cortex and the hippocampus, characterised by fewer cell layers than the isocortex. See: cerebral cortex. Synonym: heterotypic cortex. Origin: allo-+ L. Cortex, bark (cortex) (05 Mar 2000) |
|---|---|
| secondary visual cortex | See: visual cortex. (05 Mar 2000) |
| homotypic cortex | O. And C. Vogt's 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: cerebral cortex. Synonym: homotypic cortex, neocortex, neopallium. (05 Mar 2000) |
| somatosensory cortex | Area of the parietal lobe concerned with receiving general sensations. It lies posterior to the central sulcus. (12 Dec 1998) |
| stellate cells of cerebral cortex | Small star-shaped cell's in the second and fourth layers of the cortex, and large stellate cell's in the deeper part of the third layer in the visual cortex. (05 Mar 2000) |
| striate cortex | See: visual cortex. (05 Mar 2000) |
| supplementary motor cortex | A region from which, by electrical stimulation, the musculature of all bodily parts can be activated, as it also can by stimulation of the motor cortex of the precentral gyrus; the region corresponds approximately to the expansion of Brodmann's area 6 over the medial surface of the cerebral hemisphere; this area has largely a bilateral representation and is concerned primarily with tonic and postural motor activities. (05 Mar 2000) |
| deep cortex | <anatomy> Mid cortical region of lymph node, area that is particularly depleted of T lymphocytes in thymectomised animals and is referred to as the thymus dependent area. (18 Nov 1997) |
| suprarenal cortex | The outer part of the adrenal gland, consisting of three zones from without inward: zona glomerulosa, zona fasciculata, and zona reticularis; this part of the adrenal cortex yields steroid hormones such as corticosterone, deoxycorticosterone, and estrone. Synonym: cortex glandulae suprarenalis, adrenal cortex. (05 Mar 2000) |
| dysgranular cortex | The region of the cerebral cortex that is transitional between the agranular cortex of the precentral gyrus and the granular frontal cortex (Brodmann's area 8). (05 Mar 2000) |
| insular cortex | 1. An oval region of the cerebral cortex overlying the extreme capsule, lateral to the lenticular nucleus, buried in the depth of the fissura lateralis cerebri (sylvian fissure). Synonym: insular area, insular cortex, island of Reil. Synonym: island. 3. Any circumscribed body or patch on the skin. Origin: L. Island (05 Mar 2000) |
| olfactory cortex | The olfactory cortex, corresponding to the rostral half of the uncus; receiving its major afferents from the olfactory bulb, it is classified as allocortex. See: cerebral cortex. Synonym: olfactory cortex, piriform area. (05 Mar 2000) |
| orbitofrontal cortex | The cerebral cortex covering the basal surface of the frontal lobes. Synonym: fronto-orbital area. (05 Mar 2000) |
| temporal cortex | A lobe of the brain which is located laterally and below the cerebrum. Contains auditory and receptive areas. (27 Sep 1997) |
| tertiary cortex | <anatomy> Mid cortical region of lymph node, area that is particularly depleted of T lymphocytes in thymectomised animals and is referred to as the thymus dependent area. (18 Nov 1997) |
