Brodmann area 13

Region of the cerebral cortex in the human brain

Brodmann area 13 is a subdivision of the cerebral cortex in the human brain. It is part of the Brodmann areas, which are regions of the cortex defined based on their cytoarchitecture, or organization of cells. Brodmann area 13 is located in the insula, a region of the brain that is involved in diverse functions usually linked to emotion and the regulation of the body's homeostasis.

Anatomy

Brodmann areas of frontal cortex of monkey brain (Cebus apella)

Brodmann area 13 is situated in the insular cortex, which is buried within the lateral sulcus, separating the temporal lobe from the frontal lobe and parietal lobe. The insula is a complex structure that is involved in a wide range of functions, including perception, motor control, self-awareness, cognitive functioning, and interpersonal experience.

Function

Brodmann area 13, as part of the insular cortex, plays a role in various functions. It is involved in the processing of emotion, pain, and taste. The insula is also implicated in the regulation of the body's homeostasis, which includes the regulation of the autonomic nervous system, visceral sensations, and the limbic system.

Clinical significance

Damage or dysfunction in Brodmann area 13 and the insular cortex can lead to a variety of clinical symptoms. These may include deficits in emotional processing, altered pain perception, and disturbances in autonomic function. The insula has also been implicated in psychiatric disorders such as anxiety disorders, depression, and schizophrenia.
