Brodmann area 45 corresponds to which region?

Explanation:
Brodmann area 45 is defined by its cellular structure and where it sits in the frontal lobe. It lies in the inferior frontal gyrus, specifically in the middle subdivision called the pars triangularis. This region sits between the posterior pars opercularis (BA44) and the anterior pars orbitalis (BA47). The other regions mentioned belong to different lobes or different subdivisions: the angular gyrus and supramarginal gyrus are in the parietal lobe (not the inferior frontal gyrus), and the pars opercularis corresponds to BA44, not BA45. So the correct region for area 45 is the pars triangularis.
