Brodmann area 24

Brodmann area 24 animation

Brodmann area 24 is a subdivision of the cerebral cortex of the human brain defined on the basis of its cytoarchitecture. It is part of the cingulate cortex and is located in the medial aspect of the cerebral hemisphere. This area is involved in various functions including emotion formation and processing, learning, and memory.

Anatomy

Brodmann area 24 medial view

Brodmann area 24 is situated in the anterior part of the cingulate gyrus, which is a prominent structure on the medial wall of the brain. It is bounded by Brodmann area 32 anteriorly and Brodmann area 23 posteriorly. The area is characterized by a distinct cytoarchitectonic pattern that differentiates it from adjacent areas.

Cytoarchitecture

Brodmann area 24 cytoarchitectonics

The cytoarchitecture of Brodmann area 24 is defined by its unique cellular composition and organization. It is part of the granular cortex, which is distinguished by the presence of a well-developed layer IV. The neurons in this area are organized in a way that supports its role in processing complex cognitive and emotional information.

Function

Brodmann area 24 is involved in a variety of functions related to emotion and cognition. It plays a crucial role in the regulation of emotional responses and is active during tasks that require attention and decision-making. The area is also implicated in the processing of pain and is thought to contribute to the affective dimension of pain perception.

Clinical significance

Dysfunction in Brodmann area 24 has been associated with several neuropsychiatric disorders, including depression, schizophrenia, and obsessive-compulsive disorder. Abnormal activity in this area can lead to impaired emotional regulation and cognitive processing, contributing to the symptoms observed in these conditions.
