Brodmann area 9

Brodmann area 9 (BA9) is one of the cytoarchitectonic areas of the human brain. It is located in the prefrontal cortex, in the frontal lobe. This area is also known as the dorsolateral prefrontal cortex (DLPFC).

Anatomy

Brodmann area 9 is a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. It is located predominantly in the dorsolateral prefrontal cortex. It is bounded approximately by the superior frontal sulcus (which separates it from BA6), the superior precentral sulcus (separating it from BA8), and the lateral sulcus (separating it from BA10 and BA46).

Function

The dorsolateral prefrontal cortex is associated with executive functions, such as managing attention, planning and organizing, problem solving, and regulating behavior. It is also involved in working memory and decision making.

Clinical significance

Alterations in Brodmann area 9 have been implicated in a variety of neurological and psychiatric conditions, including schizophrenia, depression, bipolar disorder, and ADHD.
