68596. Anatomical terms of neuroanatomy. [edit on Wikidata] A Brodmann area is a region of the cerebral cortex, in the human or other [citation needed] primate brain, defined by its cytoarchitecture, or histological structure and organization of cells. The concept was first introduced by the German anatomist Korbinian Brodmann in the early 20th ...
The primary motor cortex (Brodmann area 4) is a brain region that in humans is located in the dorsal portion of the frontal lobe. It is the primary region of the motor system and works in association with other motor areas including premotor cortex, the supplementary motor area, posterior parietal cortex, and several subcortical brain regions ...
Brodmann area 4 refers to the primary motor cortex of the human brain. 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 ...
Brodmann area 6 (BA6) is part of the frontal cortex in the human brain. Situated just anterior to the primary motor cortex (BA4), it is composed of the premotor cortex and, medially, the supplementary motor area (SMA). This large area of the frontal cortex is believed to play a role in planning complex, coordinated movements.
Brodmann areas 3, 1, and 2 make up the primary somatosensory cortex of the human brain (or S1). [2] Because Brodmann sliced the brain somewhat obliquely, he encountered area 1 first; however, from anterior to posterior , the Brodmann designations are 3, 1, and 2, respectively.
The premotor cortex is an area of the motor cortex lying within the frontal lobe of the brain just anterior to the primary motor cortex. It occupies part of Brodmann's area 6. It has been studied mainly in primates, including monkeys and humans. The functions of the premotor cortex are diverse and not fully understood.
The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus. Motor cortex controls different muscle groups.
Brodmann area 7 is part of the parietal cortex in the human brain.Situated posterior to the primary somatosensory cortex (Brodmann areas 3, 1 and 2), and superior to the occipital lobe, this region is believed to play a role in visuo-motor coordination (e.g., in reaching to grasp an object).
