| gyrus lingualis | A relatively short horizontal convolution on the inferomedial aspect of the occipital and temporal lobes, demarcated from the lateral occipitotemporal or fusiform gyrus by the deep collateral sulcus, from the cuneus by the calcarine sulcus; its anterior extreme abuts the isthmus of the parahippocampal gyrus; the medial or upper strip of the gyrus forming the lower bank of the calcarine sulcus corresponds to the inferior half of the striate area or primary visual cortex and represents the contralateral upper quadrant of the binocular field of vision. Synonym: gyrus lingualis, gyrus occipitotemporalis medialis, medial occipitotemporal gyrus. (05 Mar 2000) |
|---|---|
| gyrus longus insulae | The most posterior and longest of the slender straight gyri that compose the insula. Synonym: gyrus longus insulae. (05 Mar 2000) |
| gyrus occipitotemporalis lateralis | An extremely long convolution extending lengthwise over the inferior aspect of the temporal and occipital lobes, demarcated medially by the collateral sulcus from the lingual gyrus and the anterior part of the parahippocampal gyrus, laterally by the inferior temporal sulcus from the inferior temporal gyrus. Synonym: gyrus occipitotemporalis lateralis, gyrus fusiformis, lateral occipitotemporal gyrus, lobulus fusiformis. (05 Mar 2000) |
| gyrus occipitotemporalis medialis | A relatively short horizontal convolution on the inferomedial aspect of the occipital and temporal lobes, demarcated from the lateral occipitotemporal or fusiform gyrus by the deep collateral sulcus, from the cuneus by the calcarine sulcus; its anterior extreme abuts the isthmus of the parahippocampal gyrus; the medial or upper strip of the gyrus forming the lower bank of the calcarine sulcus corresponds to the inferior half of the striate area or primary visual cortex and represents the contralateral upper quadrant of the binocular field of vision. Synonym: gyrus lingualis, gyrus occipitotemporalis medialis, medial occipitotemporal gyrus. (05 Mar 2000) |
| gyrus parahippocampalis | A long convolution on the medial surface of the temporal lobe, forming the lower part of the fornicate gyrus, extending from behind the splenium corporis callosi forward along the dentate gyrus of the hippocampus from which it is demarcated by the hippocampal fissure. The anterior extreme of the gyrus curves back upon itself, forming the uncus, the major location of the olfactory cortex. See: entorhinal area. Synonym: gyrus parahippocampalis, hippocampal convolution, hippocampal gyrus. (05 Mar 2000) |
| gyrus paraterminalis | A slender vertical whitish band immediately anterior to the lamina terminalis and anterior commissure; contrary to its name, it is not a cortical convolution but is the ventral continuation of the transparent septum. Synonym: area subcallosa, gyrus paraterminalis, gyrus subcallosus, pedunculus corporis callosi, corpus paraterminale, paraterminal body, paraterminal gyrus, peduncle of corpus callosum, precommissural septal area, subcallosal area, Zuckerkandl's convolution. (05 Mar 2000) |
| gyrus postcentralis | The anterior convolution of the parietal lobe, bounded in front by the central sulcus (fissure of Rolando) and posteriorly by the interparietal sulcus. Synonym: gyrus postcentralis, ascending parietal convolution, ascending parietal gyrus, posterior central convolution, posterior central gyrus. (05 Mar 2000) |
| gyrus precentralis | Bounded posteriorly by the central sulcus and anteriorly by the precentral sulcus. Synonym: gyrus precentralis, anterior central convolution, anterior central gyrus, ascending frontal convolution, ascending frontal gyrus. (05 Mar 2000) |
| gyrus rectus | A gyrus running along the medial part of the orbital surface of the frontal lobe of the cerebral hemisphere. It is bounded laterally by the olfactory sulcus. Synonym: gyrus rectus. (05 Mar 2000) |
| gyrus subcallosus | A slender vertical whitish band immediately anterior to the lamina terminalis and anterior commissure; contrary to its name, it is not a cortical convolution but is the ventral continuation of the transparent septum. Synonym: area subcallosa, gyrus paraterminalis, gyrus subcallosus, pedunculus corporis callosi, corpus paraterminale, paraterminal body, paraterminal gyrus, peduncle of corpus callosum, precommissural septal area, subcallosal area, Zuckerkandl's convolution. (05 Mar 2000) |
| gyrus supramarginalis | A folded convolution capping the posterior extremity of the lateral (sylvian) sulcus; together with the angular gyrus, it forms the inferior half of the parietal lobe. Synonym: gyrus supramarginalis, supramarginal convolution. (05 Mar 2000) |
| gyrus temporalis inferior | A sagittal convolution on the inferolateral border of the temporal lobe of the cerebrum, separated from the middle temporal gyrus by the inferior temporal sulcus. On the inferior surface of the temporal lobe it is separated from the medial occipitotemporal gyrus by the occipitotemporal sulcus. It includes the lateral occipitotemporal gyrus. Synonym: gyrus temporalis inferior, inferior temporal convolution, third temporal convolution. (05 Mar 2000) |
| gyrus temporalis medius | A longitudinal gyrus on the lateral surface of the temporal lobe, between the superior and inferior temporal sulci. Synonym: gyrus temporalis medius, middle temporal convolution, second temporal convolution. (05 Mar 2000) |
| gyrus temporalis superior | A longitudinal gyrus on the lateral surface of the temporal lobe between the lateral (sylvian) fissure and the superior temporal sulcus. Synonym: gyrus temporalis superior, first temporal convolution, superior temporal convolution. (05 Mar 2000) |
| middle frontal gyrus | A convolution on the convexity of each frontal lobe of the cerebrum running in an anteroposterior direction between the superior and inferior frontal sulci. Synonym: gyrus frontalis medius, middle frontal convolution. (05 Mar 2000) |
