gyrus[ji´rus] (pl. gy´ri) (L.)
one of the many convolutions of the surface of the cerebral hemispheres caused by infolding of the cortex, separated by fissures or sulci; called also cerebral gyrus.
angular gyrus one continuous anteriorly with the supramarginal gyrus.
annectent gyri various small folds on the cerebral surface that are too inconstant to bear specific names; called also gyri transitivi.
Broca's gyrus inferior frontal gyrus.
central gyrus, anterior precentral gyrus.
central gyrus, posterior postcentral gyrus.
cerebral gyrus gyrus.
cingulate gyrus (gyrus cin´guli) an arch-shaped convolution situated just above the corpus callosum.
frontal gyrus any of the three (inferior, middle, and superior) gyri of the frontal lobe.
fusiform gyrus one on the inferior surface of the hemisphere between the inferior temporal and parahippocampal gyri, consisting of a lateral (lateral occipitotemporal gyrus) and a medial (medial occipitotemporal gyrus) part.
hippocampal gyrus (gyrus hippocam´pi) one on the inferior surface of each cerebral hemisphere, lying between the hippocampal and collateral fissures; called also parahippocampal gyrus.
infracalcarine gyrus (lingual gyrus) one on the occipital lobe that forms the inferior lip of the calcerine sulcus and, together with the cuneus, the visual cortex.
marginal gyrus the middle frontal gyrus.
occipital gyrus any of the three (superior, middle, and inferior) gyri of the occipital lobe.
occipitotemporal gyrus, lateral the lateral portion of the fusiform gyrus.
occipitotemporal gyrus, medial the medial portion of the fusiform gyrus.
orbital gyri irregular gyri on the orbital surface of the frontal lobe.
parahippocampal gyrus hippocampal gyrus.
paraterminal gyrus a thin sheet of gray matter in front of and ventral to the genu of the corpus callosum.
postcentral gyrus the convolution of the frontal lobe immediately behind the central sulcus; the primary sensory area of the cerebral cortex; called also posterior central gyrus.
precentral gyrus the convolution of the frontal lobe immediately in front of the central sulcus; the primary motor area of the cerebral cortex; called also anterior central gyrus.
gyrus rec´tus a cerebral convolution on the orbital aspect of the frontal lobe.
supramarginal gyrus that part of the inferior parietal convolution which curves around the upper end of the fissure of Sylvius.
temporal gyrus any of the gyri of the temporal lobe, including inferior, middle, superior, and transverse temporal gyri; the more prominent of the latter (anterior transverse temporal gyrus) represents the cortical center for hearing.
gy´ri transiti´vi annectent gyri.
uncinate gyrus the uncus.

a folded convolution in the inferior parietal lobule formed by the union of the posterior ends of the superior and middle temporal gyri; a gyrus located around the caudal terminus of the superior temporal sulcus.

A region of the inferior parietal lobe of the brain that is involved in the processing of auditory and visual input and in the comprehension of language.

angular gyrusA region of the inferior parietal lobe near the superior edge of the temporal lobe, and just posterior to the supramarginal gyrus; it is involved in a number of processes related to language and cognition (Brodmann area 39), which links visual input with stored sounds of language.
