diffusion tensor imaging
most of the A.F. goes to the lexical semantic cortex

lateral superior temporal gyrus responsible for call processing (lesion makes them unable to distinguish between calls), but lesion in broca's homolog doesn't eliminate vocalization (proves that sounds are involuntary--simply expressions of arousal)
What did the study of the arcuate fasciculus in macaques vs humans show?
humans more extensive, associated with meaning
