In what area of functioning is the prefrontal cortex not primarily involved?

The prefrontal cortex is heavily involved in higher-level functions such as decision-making, social behavior moderation, and complex cognitive behavior, which are integral to personality expression, regulation of social interactions, and planning. While the prefrontal cortex does contribute to language and comprehension through its connections with other areas of the brain, it is not the primary region responsible for these functions. Language comprehension is primarily managed by areas such as Broca's and Wernicke's areas in the left hemisphere of the brain. Therefore, identifying language comprehension as the area where the prefrontal cortex is not primarily involved is an accurate understanding of the brain's functional specialization.
