Supplementary motor area labelled SMA. The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. Classically, the motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus.
What is the secondary motor cortex?
Other regions of the cortex involved in motor function are called the secondary motor cortices. These regions include the posterior parietal cortex, the premotor cortex, and the supplementary motor area (SMA). The posterior parietal cortex is involved in transforming visual information into motor commands.
What lobe is the supplementary motor cortex in?
IV. Supplementary Motor Cortex. The SMA was first described in the cortex of the medial wall of the frontal lobe of humans more than 50 years ago. In monkeys, SMA extends onto the dorsal surface of the medial frontal lobe just rostral to M1 and medial to PMD (Fig.
