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
The association cortex is a part of the cerebral cortex that performs complex cognitive functions. [1] [2] Unlike primary sensory or motor areas, which process specific sensory inputs or motor outputs, the association cortex integrates information from various sources to support higher-order cognitive processes. This integration allows for ...
The leg area is located close to the midline, in interior sections of the motor area folding into the medial longitudinal fissure. The lateral, convex side of the primary motor cortex is arranged from top to bottom in areas that correspond to the buttocks, torso, shoulder, elbow, wrist, fingers, thumb, eyelids, lips, and jaw.
On similar criteria Brodmann [27] in 1909 also distinguished between his area 4 (coextensive with the primary motor cortex) and his area 6 (coextensive with the premotor cortex). Vogt and Vogt [1] [2] in 1919 also suggested that motor cortex was divided into a primary motor cortex (area 4) and a higher-order motor cortex (area 6) adjacent to it ...
The motor areas are located in both hemispheres of the cortex. The motor areas are very closely related to the control of voluntary movements, especially fine fragmented movements performed by the hand. The right half of the motor area controls the left side of the body, and vice versa. Two areas of the cortex are commonly referred to as motor:
The supplementary motor area (SMA) is a part of the motor cortex of primates that contributes to the control of movement. It is located on the midline surface of the hemisphere just in front of (anterior to) the primary motor cortex leg representation. In monkeys, the SMA contains a rough map of the body.

Parietal ventral area is the somatosensory relay to the premotor cortex and somatosensory memory hub, BA5. BA5 is the topographically organized somato memory field and association area. BA1 processes texture info while BA2 processes size and shape information. Area S2 processes light touch, pain, visceral sensation, and tactile attention.
