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 ...
The middle frontal gyrus makes up about one-third of the frontal lobe of the human brain. (A gyrus is one of the prominent "bumps" or "ridges" on the cerebral cortex . The middle frontal gyrus, like the inferior frontal gyrus and the superior frontal gyrus , is more of a region in the frontal gyrus than a true gyrus.
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 .
The inferior frontal gyrus is divided into three parts – the orbital part, the triangular part and the opercular part. [3] The frontal lobe contains most of the dopaminergic neurons in the cerebral cortex. The dopaminergic pathways are associated with reward, attention, short-term memory tasks, planning, and motivation.
Opercular part of inferior frontal gyrus (pars opercularis), (cortex posterior to the ascending ramus of the lateral sulcus), is the part of frontal lobe that overlies the insular cortex and may be associated with recognizing a tone of voice in spoken native languages. [6]
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 precentral gyrus is a prominent gyrus on the surface of the posterior frontal lobe of the brain. It is the site of the primary motor cortex that in humans is cytoarchitecturally defined as Brodmann area 4 .
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 temporalis superior; Middle temporal gyrus, lat. gyrus temporalis medius; Inferior temporal gyrus, lat ...
