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 ...
Brodmann area 44, or BA44, is part of the frontal cortex in the human brain.Situated just anterior to premotor cortex and on the lateral surface, inferior to BA9.. This area is also known as pars opercularis (of the inferior frontal gyrus), and it refers to a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex.
The DLPFC is not an anatomical structure, but rather a functional one. It lies in the middle frontal gyrus of humans (i.e., lateral part of Brodmann's area (BA) 9 and 46 [2]). In macaque monkeys, it is around the principal sulcus (i.e., in Brodmann's area 46 [3] [4] [5]).
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 .
Triangular part of inferior frontal gyrus (pars triangularis), (cortex between the ascending ramus and the horizontal ramus of the lateral sulcus). It may be associated with the ability to translate from a secondary or tertiary language back to one's native language. [8] Orbital part of inferior frontal gyrus (pars orbitalis) (cortex inferior ...
These are named, from their position, the medial, anterior, lateral, and posterior, orbital gyri. The medial orbital gyrus presents a well-marked antero-posterior sulcus, the olfactory sulcus , for the olfactory tract ; the portion medial to this is named the straight gyrus , and is continuous with the superior frontal gyrus on the medial surface.
It is located in the posterior portion of the frontal lobe. Brodmann area 4 is part of the precentral gyrus . The borders of this area are: the precentral sulcus in front ( anteriorly ), the medial longitudinal fissure at the top ( medially ), the central sulcus in back ( posteriorly ), and the lateral sulcus along the bottom ( laterally ).
In the human brain, it is located on the portions of the precentral gyrus that are not occupied by Brodmann area 4; furthermore, BA6 extends onto the caudal portions of the superior frontal and middle frontal gyri. It extends from the cingulate sulcus on the medial aspect of the hemisphere to the lateral sulcus on the lateral aspect. It is ...
