WebFunctions of the Primary Motor Cortex (MI) Electrical stimulation of the motor cortex in humans shows that there is a somatotopic map of the musculature on the cortex: stimulation with small electrical currents produces contraction of muscle groups and movements of joints on the opposite side of the body. There is a broad representation of the different body parts in the primary motor cortex in an arrangement called a motor homunculus (Latin: little person). 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 … WebDec 17, 2024 · The motor cortex function is an execution of voluntary movements.
