Anatomical terms of neuroanatomy

Brodmann area 44, or BA44, is part of the frontal cortex in the human brain. Situated just anterior to premotor cortex (BA6) and on the lateral surface, inferior to BA9.

This area is also known as pars opercularis (of the inferior frontal gyrus), and it refers to a subdivision of the

triangular part of inferior frontal gyrus (Brodmann area 45
BA 45).

Functions

Together with left-hemisphere

Recent neuroimaging studies show BA44 involvement in selective response suppression in go/no-go tasks and is therefore believed to play an important role in the suppression of response tendencies.[3] This may apply mainly to the right BA44.[4] Neuroimaging studies also demonstrate that area 44 is related to hand movements.[5]

The presence of mirror neurons in Broca's area suggests language evolved from a gesture imitating system. Broca's area is also involved with theory of mind (ToM), which is the ability to understand the mental state of others through observation, inferring, and projecting.[6]

Trivia

fMRI while doing complex calculations, which showed brain activity in this region was absent. Instead there was activity somewhat higher than that of area 44 and closer to the motor cortex.[7]
