Does it talk the talk? On the role of basal ganglia in emotive speech processing.
Commentary on Ackermann et al. "Brain mechanisms of acoustic communication in humans and nonhuman primates: An evolutionary perspective"
Ackermann et al.'s phylogenetic account of speech argues that the basal ganglia imbue speech
with emotive content. However, a body of work on auditory/emotive processing is
inconsistent with attributing this function exclusively to these structures. The account
further overlooks the possibility that the emotion-integration function may be at least in
part mediated by the cortico-ponto-cerebellar system
