The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making.In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47.
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 frontal lobe is covered by the frontal cortex. [2] The frontal cortex includes the premotor cortex and the primary motor cortex – parts of the motor cortex. The front part of the frontal cortex is covered by the prefrontal cortex. The nonprimary motor cortex is a functionally defined portion of the frontal lobe.
The medial prefrontal cortex (mPFC) is composed of BA12, BA25, and anterior cingulate cortex: BA32, BA33, BA24. [1] Within that area is the dorsal nexus, which interconnects many parts of the brain. [19] The ventral prefrontal cortex is composed of areas BA11, BA13, and BA14. [1] (Also see the definition of the orbitofrontal cortex.)
The frontal lobe consists of the prefrontal cortex which is located in the most anterior (farthest away) section of the frontal lobe. It is critical for one's working memory and executive control which helps keep goals and complex tasks organized. The divisions of the prefrontal cortex include orbital, medial, and lateral prefrontal
Area 46 – Dorsolateral prefrontal cortex; Area 47 – Orbital part of inferior frontal gyrus; Area 48 – Retrosubicular area (a small part of the medial surface of the temporal lobe) Area 49 – Parasubicular area in a rodent; Area 52 – Parainsular area (at the junction of the temporal lobe and the insula) (*) Area only found in non-human ...
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.
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.
