ventral prefrontal cortices
The primary motor regions (BA4a and BA4p), the planum temporale (Wernicke's region: Te3),
the ventral prefrontal cortex (Broca's region: BA44 and BA45), and the rostral inferior parietal cortex BA40 (merged PFop, PFt, PF, PFm, and PFcm) were spatially defined using probabilistic cytoarchitectonic maps using the SPM anatomy toolbox v. 1.6.
