Researchers have discovered that a part of the brain associated with working memory and multisensory integration may also play an important role in how the brain processes social cues. Previous research has shown that neurons in the ventrolateral prefrontal cortex (VLPFC) integrate faces and voices -- but new research shows that neurons in the VLPFC play a role in processing both the identity of the 'speaker' and the expression conveyed by facial gestures and vocalizations.
