The superior frontal sulcus is a sulcus between the superior frontal gyrus and the middle frontal gyrus, that defines the lateral limit of the Superior frontal gyrus. [1]
In neuroanatomy, the superior frontal gyrus (SFG, also marginal gyrus) is a gyrus – a ridge on the brain's cerebral cortex – which makes up about one third of the frontal lobe. It is bounded laterally by the superior frontal sulcus. [1] The superior frontal gyrus is one of the frontal gyri.
The medial and superior frontal gyri are two of the frontal gyri of the frontal lobe. The portion on the lateral surface of the hemisphere is usually more or less completely subdivided into an upper and a lower part by an antero-posterior sulcus, the paramedial sulcus, which, however, is frequently interrupted by bridging gyri.
Axial sulcus develops in the long axis of a rapidly growing homogeneous area e.g. postcalcarine sulcus in the long axis of the striate area. Operculated sulcus separates by its lips into two areas and contains a third area in the walls of the sulcus e.g. lunate sulcus is an operculated sulcus, separating the striate and parastriate areas.
The other main gyrus of the frontal lobe is the precentral gyrus which is vertically oriented, and runs parallel with the precentral sulcus. The uppermost of the five gyri is the superior frontal gyrus , [ 1 ] below this is the middle frontal gyrus , and below this is the inferior frontal gyrus .
Specifically, different patterns appear in the superior frontal sulcus, Sylvian fissure, inferior frontal gyrus, superior temporal gyrus, and olfactory sulci. [45] These areas relate to working memory, emotional processing, language, and eye gaze, [ 46 ] and their difference in location and level of gyrification when compared to a neurotypical ...
The superior sulcus (groove) may refer to: Superior sulcus of the human brain. Superior frontal sulcus, a sulcus between the superior frontal gyrus and the middle frontal gyrus . Superior temporal sulcus, the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe; A groove in the first rib.
Superior frontal gyrus, lat. gyrus frontalis superior; Middle frontal gyrus, lat. gyrus frontalis medius; Inferior frontal gyrus, lat. gyrus frontalis inferior with 3 parts: pars opercularis (Brodmann area 44) pars triangularis (Brodmann area 45), and pars orbitalis (orbital part of inferior frontal gyrus) Superior temporal gyrus, lat. gyrus ...
