Brodmann area 5

Brodmann area 5 is one of the cytoarchitecturally defined regions of the brain. It is named after its discoverer, Korbinian Brodmann, a German neurologist. Brodmann area 5 is part of the parietal cortex, located in the postcentral gyrus and the superior parietal lobule.

Anatomy

Brodmann area 5 is situated in the human brain's parietal lobe, posterior to the primary somatosensory cortex (Brodmann areas 1, 2, and 3). It is bounded by the central sulcus anteriorly and the interparietal sulcus posteriorly.

Function

Brodmann area 5 is involved in various cognitive functions, including spatial awareness and proprioception. It receives inputs from the primary somatosensory cortex and integrates this information to provide a complex understanding of the body's position in space.

Clinical significance

Damage to Brodmann area 5 can result in astereognosis, a condition characterized by the inability to identify objects by touch alone. It can also lead to apraxia, a motor disorder caused by damage to the brain.
