Neural competition between concurrent speech production and other speech perception

Understanding others’ speech while individuals simultaneously produce utterances implies neural competition and requires specific mechanisms for a resolution given that previous studies proposed opposing signal dynamics both processes in the auditory cortex (AC). We here used neuroimaging humans to investigate this by lateralized stimulations with other samples ipsilateral or contralateral feedback of actively produced self form various vowels. In experiment 1, we show, first, classifications during active lead activity planum temporale (PTe) when were presented together only left right ear. The PTe also seemed indifferently respond single samples. Second, anterior superior temporal (STC) was found dichotic (i.e. separate ears). Unlike studies, STC supported rather than processing. Furthermore, mid more involved These results signify processing beyond general PTe. Third, recognition context listening recorded 2 led largely symmetric additionally inferior frontal subregions. latter previously reported be generally relevant perception classification, but classification challenged not Altogether, unlike formerly established brain networks uncompetitive perception, seemingly leads reordering, functional reassignment, unusual lateralization AC activations.
