Brodmann area 44

Brodmann area 44 is one of the subdivisions of the frontal lobe in the human brain. It is also known as the pars opercularis and is part of the Broca's area, which is involved in speech production.

Anatomy

Brodmann area 44 is located in the posterior part of the frontal lobe. It is bounded dorsally by the precentral sulcus, ventrally by the lateral sulcus (Sylvian fissure), and rostrally by the Brodmann area 45.

Function

Brodmann area 44 is involved in various cognitive functions, including language comprehension, speech production, and working memory. It is also implicated in the processing of complex actions and the control of behavior.

Clinical significance

Damage to Brodmann area 44 can result in Broca's aphasia, a condition characterized by difficulties in speech production but relatively preserved comprehension.
