Postcentral sulcus

From Wikipedia, the free encyclopedia

Postcentral sulcus of the human brain.

Lateral surface of left cerebral hemisphere, viewed from the side.

The postcentral sulcus of the parietal lobe lies parallel to, and behind, the central sulcus in the human brain. (A sulcus is one of the prominent grooves on the surface of the brain.)

The precentral sulcus divides the postcentral gyrus from the remainder of the parietal lobe.

v • d • e Brain: telencephalon (cerebrum, cerebral cortex, cerebral hemispheres)
primary sulci/fissures	medial longitudinal, lateral, central, parietoöccipital, calcarine, cingulate
frontal lobe	precentral gyrus (primary motor cortex, 4), precentral sulcus, superior frontal gyrus (6, 8), middle frontal gyrus (46), inferior frontal gyrus (Broca's area, 44-pars opercularis, 45-pars triangularis), prefrontal cortex (orbitofrontal cortex, 9, 10, 11, 12, 47)
parietal lobe	postcentral sulcus, postcentral gyrus (1, 2, 3, 43), superior parietal lobule (5), inferior parietal lobule (39-angular gyrus, 40), precuneus (7), intraparietal sulcus
occipital lobe	primary visual cortex (17), cuneus, lingual gyrus, 18, 19 (18 and 19 span whole lobe)
temporal lobe	transverse temporal gyrus (41-42-primary auditory cortex), superior temporal gyrus (38, 22-Wernicke's area), middle temporal gyrus (21), inferior temporal gyrus (20), fusiform gyrus (36, 37)
limbic lobe/fornicate gyrus	cingulate cortex/cingulate gyrus, anterior cingulate (24, 32, 33), posterior cingulate (23, 31), isthmus (26, 29, 30), parahippocampal gyrus (piriform cortex, 25, 27, 35), entorhinal cortex (28, 34)
subcortical/insular cortex	rhinencephalon, olfactory bulb, olfactory tract, corpus callosum (splenium, genu, rostrum), lateral ventricles, septum pellucidum, ependyma, internal capsule, corona radiata, external capsule, fornix (commissure of fornix), anterior commissure, posterior commissure
hippocampal formation	dentate gyrus, hippocampus, subiculum
basal ganglia	striatum (caudate nucleus, putamen), lentiform nucleus (putamen, globus pallidus), claustrum, extreme capsule, amygdala, nucleus accumbens
Some categorizations are approximations, and some Brodmann areas span gyri.
