A third definition of the prefrontal cortex is the area of frontal cortex whose electrical stimulation does not lead to observable movements. For example, in 1890 David Ferrier [17] used the term in this sense. One complication with this definition is that the electrically "silent" frontal cortex includes both granular and non-granular areas. [11]
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 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 dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. [1] The DLPFC is not an anatomical structure, but rather a functional one.
In humans the frontal pole area of the prefrontal cortex includes not only area 10 but part of BA 9. BA 10 also extends beyond the pole area into its ventromedial side. In Guenon monkeys, the pole area is filled by BA 12 (and its BA 10 is found in the orbital prefrontal region).
Area 9 – Dorsolateral prefrontal cortex; Area 10 – Anterior prefrontal cortex (most rostral part of superior and middle frontal gyri) Area 11 – Orbitofrontal area (orbital and rectus gyri, plus part of the rostral part of the superior frontal gyrus) Area 12 – Orbitofrontal area (used to be part of BA11, refers to the area between the ...
The FPN is primarily composed of the rostral lateral and dorsolateral prefrontal cortex (especially the middle frontal gyrus) and the anterior inferior parietal lobule. Additional regions include the middle cingulate gyrus and potentially the dorsal precuneus , posterior inferior temporal lobe , dorsomedial thalamus and the head of the caudate ...
Brodmann area 46, or BA46, is part of the frontal cortex in the human brain.It is between BA10 and BA45.. BA46 is known as middle frontal area 46.In the human brain it occupies approximately the middle third of the middle frontal gyrus and the most rostral portion of the inferior frontal gyrus.
