Brodmann area 6

Brodmann area 6 is one of the cytoarchitectonic areas of the human brain. It is located in the frontal lobe, and it is part of the premotor cortex and the supplementary motor area (SMA). This area plays a crucial role in the planning of complex, coordinated movements.

Anatomy

Brodmann area 6 is situated on the medial and lateral aspects of the cerebral hemisphere. It is bounded approximately by the precentral sulcus, the medial longitudinal fissure, and the cingulate sulcus. It encompasses both the premotor cortex and the supplementary motor area.

Function

The premotor cortex is involved in the planning and guidance of movements, while the supplementary motor area is involved in the initiation of movements, orientation of the eyes and head, and planning bimanual and sequential movements.

Clinical significance

Damage to Brodmann area 6 can result in apraxia, a disorder of motor planning. It can also lead to loss of coordination of motor movement (ataxia), inability to execute learned purposeful movements, despite having the desire and the physical ability to perform the movements.
