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 inferior frontal gyrus includes Broca's area. On the inferior or ventral surface of the frontal lobe including the orbitofrontal cortex is the orbital gyrus. This is also called the orbital gyri because it is separated into four sections or gyri: anterior, posterior, lateral, and medial. The most medial gyrus of the frontal lobes on the ...
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 ...
BA 10 is divided into three sub-areas, 10p, 10m and 10r. 10p occupies the frontal pole while the other two cover the ventromedial part of the prefrontal cortex. [7] Area 10m has thin layers II and IV and a more prominent layer V. In contrast, area 10r has a prominent layer II and a thicker layer IV.
In the guenon, Brodmann area 32 is a subdivision of the cytoarchitecturally defined cingulate region of cerebral cortex.This area was named 25 in Brodmann-1905 and labeled 25 in a figure contributed by Brodmann in Mauss-1908.
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 .
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. [1] It contributes to the dorsolateral and medial prefrontal cortex.
Brodmann area 8. The frontal eye fields (FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, [1] of the primate brain.In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus, consisting of a frontal and parietal portion.
