Auditory cortical micro-networks show differential connectivity during voice and speech processing in humans

Abstract

Florence Steiner, Marine Bobin, et al. apply dynamic causal modelling on fMRI data from healthy participants to investigate local microcircuits within the voice area of the auditory cortex. Their results identify subregions of the auditory cortex that are sensitive to speech, and highlight functional heterogeneity among temporal voice areas that may underlie voice signal processing in humans.
