Brodmann area 44, or BA44, is part of the frontal cortex in the human brain.Situated just anterior to premotor cortex 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 cytoarchitecturally defined frontal region of cerebral cortex.
The pars opercularis acts indirectly through the motor cortex to control the motor aspect of speech production, and codes motor programs for this system, while the auditory cortex (via the temporoparietal junction in the lateral sulcus (Sylvian fissure) houses a series of sensory targets. Together, these areas function as a sensory-motor loop ...
Later work by Nixon et al. (2004) [17] showed that when the pars opercularis (situated in the posterior part of Broca's area) was stimulated under rTMS there was an increase in reaction times in a phonological task.
The orbital part of inferior frontal gyrus also known as the pars orbitalis is the orbital part of the inferior frontal gyrus. [1]In humans, this region is bordered by the triangular part of the inferior frontal gyrus (pars triangularis) and, surrounding the anterior horizontal limb of the lateral sulcus, a portion of the opercular part of inferior frontal gyrus (pars opercularis).
A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells.
Brodmann area 45 (BA45), is part of the frontal cortex in the human brain.It is situated on the lateral surface, inferior to BA9 and adjacent to BA46.. This area in humans occupies the triangular part of inferior frontal gyrus (H) and, surrounding the anterior horizontal limb of the lateral sulcus (H), a portion of the orbital part of the inferior frontal gyrus (H).

Reductions have also been reported in the right inferior frontal gyrus, insula, pars triangularis, pars opercularis, and middle and superior temporal gyrus. [64] Structural neuroimaging in people who are susceptible to bipolar disorder (i.e., have a number of relatives with bipolar disorder) have produced few consistent results.
