Dorsomedial prefrontal cortex

The Dorsomedial Prefrontal Cortex (dmPFC) is a part of the prefrontal cortex, the anterior part of the frontal lobes of the brain. It is involved in various cognitive functions, including decision-making, social cognition, and working memory.

Anatomy

The dorsomedial prefrontal cortex is located in the uppermost part of the frontal lobes, directly above the medial prefrontal cortex. It is bordered by the superior frontal gyrus to the north, the cingulate cortex to the south, and the precentral gyrus to the west.

Function

The dmPFC is involved in a variety of cognitive functions. It plays a crucial role in decision-making, particularly in situations that involve uncertainty or ambiguity. It is also involved in social cognition, the process by which we understand and interpret the behaviors and intentions of others. Additionally, the dmPFC is implicated in working memory, the ability to hold and manipulate information in the mind over short periods of time.

Clinical Significance

Abnormalities in the dmPFC have been associated with a number of psychiatric disorders, including schizophrenia, depression, and anxiety disorders. In particular, hyperactivity in the dmPFC has been linked to the symptoms of social anxiety disorder.

Etymology

The term "dorsomedial prefrontal cortex" is derived from the Latin words "dorsum" (back), "medius" (middle), and "frontalis" (of the forehead), reflecting its location in the brain.
