| superior frontal gyrus | A broad convolution running in an anteroposterior direction on the medial edge of the convex surface and of each frontal lobe. Synonym: gyrus frontalis superior, marginal gyrus, superior frontal convolution. (05 Mar 2000) |
|---|---|
| superior occipital gyrus | A gyrus lying above the lateral occipital sulcus on the lateral surface of the occipital lobe. (05 Mar 2000) |
| superior parietal gyrus | The area of the convex surface of the parietal lobe of the cerebrum lying between the longitudinal fissure and the interparietal sulcus behind the posterior central gyrus; it is continuous with the precuneus on the medial aspect of the hemisphere. Synonym: lobulus parietalis superior, superior parietal gyrus. (05 Mar 2000) |
| supracallosal gyrus | A thin layer of gray matter on the dorsal surface of the corpus callosum in which the medial and lateral longitudinal stria lie embedded. The indusium griseum is a rudimentary component of the hippocampus, continuous caudally around the splenium of the corpus callosum with the fasciolar gyrus, a slender convolution in turn continuous with the dentate gyrus of the hippocampus; rostrally the indusium griseum curves around the genu and rostrum of corpus callosum and extends ventralward to the olfactory trigone as the tenia tecta or rudimentum hippocampi, hidden in the depth of the posterior parolfactory sulcus that marks the anterior border of the subcallosal gyrus or precommissural septum. Synonym: supracallosal gyrus. (05 Mar 2000) |
| deep transitional gyrus | The transverse gyrus of the embryo which in development becomes buried in the depth of the central sulcus of the cerebral hemisphere. Dentate gyrus, one of the two interlocking gyri composing the hippocampus, the other one being the Ammon's horn. Synonym: gyrus dentatus, dentate fascia, fascia dentata hippocampi. (05 Mar 2000) |
| supramarginal gyrus | 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) |
| dentate gyrus | Serrated strip of gray matter under the medial border of the hippocampus and in its depths. It is an archicortex which develops along the edge of the hippocampal fissure and which consists of molecular, granular, and polymorphic layers. The molecular layer is continuous with that of the hippocampus in the depths of the hippocampal fissure. (carpenter and sutin, human neuroanatomy, 8th ed, p626) (12 Dec 1998) |
| isthmus of cingulate gyrus | The narrowing of the cingulate gyrus, at its transition with the hippocampal gyrus behind and below the splenium of the corpus callosum, caused by the anterior extension of the conjoined parieto-occipital and calcarine sulci. Synonym: isthmus gyri cinguli, isthmus of gyrus fornicatus, isthmus of limbic lobe. (05 Mar 2000) |
| isthmus of gyrus fornicatus | The narrowing of the cingulate gyrus, at its transition with the hippocampal gyrus behind and below the splenium of the corpus callosum, caused by the anterior extension of the conjoined parieto-occipital and calcarine sulci. Synonym: isthmus gyri cinguli, isthmus of gyrus fornicatus, isthmus of limbic lobe. (05 Mar 2000) |
| tail of dentate gyrus | A slender whitish band, the attenuated anterior continuation of the dentate gyrus (fascia dentata), crossing transversally the surface of the recurved part of the uncus gyri parahippocampalis. Synonym: band of Giacomini, cauda fasciae dentatae, frenulum of Giacomini, tail of dentate gyrus. (05 Mar 2000) |
| transitional gyrus | A small convolution connecting two lobes or two main gyri in the depth of a sulcus. Synonym: annectent gyrus, transitional convolution. (05 Mar 2000) |
| uncinate gyrus | Origin: L. <zoology> A hook or claw. Source: Websters Dictionary (01 Mar 1998) |
| fasciolar gyrus | A small paired band that passes around the splenium of the corpus callosum from the lateral longitudinal stria to the dentate gyrus. Synonym: gyrus fasciolaris, fascia cinerea, fasciola cinerea. (05 Mar 2000) |
| fornicate gyrus | The horseshoe-shaped cortical convolution bordering the hilus of the cerebral hemisphere; its upper limb is formed by the cingulate gyrus, its lower by the parahippocampal gyrus. Synonym: gyrus fornicatus. (05 Mar 2000) |
| lateral occipitotemporal gyrus | 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) |
