Premotor_Area

The Premotor Area is involved in the control of complex voluntary movements of the contralateral half of the body particularly those of the axial muscles. Structures: Brodmann’s Areas Cortical Areas Corticospinal Tract Frontal Lobe Middle Frontal Gyrus Primary Motor Area Superior Frontal Gyrus Ventral Anterior Nucleus Ventral Posterior Nucleus Information: The premotor area is located in the frontal lobe on the posterior part of the superior and middle frontal gyri. It is adjacent to the primary motor area and corresponds to Brodmann's area 6. Its major inputs come from the primary motor area and the motor (ventral anterior and ventral lateral) nuclei of the thalamus. Major outputs go to the primary motor area and the corticospinal tract. Like the primary motor area, the premotor area is also topographically organised but it has a higher threshold (is less sensitive) to stimulation which results in contractions of muscle groups, rather than individual muscles. The premotor area is known to be active just prior to and during a movement and is thought to be involved in some way in programming the activity of neurons in the primary motor area. Damage to the premotor area results in apraxia, an inability to carry out complex voluntary movements eg. the patients can't dress themselves. The patient can't point to his/her nose voluntarily (if asked to do so) but can do so subconsciously, if, for example, the nose itches.
