Abstract

The issue of whether speech is supported by the same neural substrates as non-speech vocal tract gestures has been contentious. In this fMRI study we tested whether producing non-speech vocal tract gestures in humans shares the same functional neuroanatomy as non-sense speech syllables. Production of non-speech vocal tract gestures, devoid of phonological content but similar to speech in that they had familiar acoustic and somatosensory targets, was compared to the production of speech syllables without meaning. Brain activation related to overt production was captured with BOLD fMRI using a sparse sampling design for both conditions. Speech and non-speech were compared using voxel-wise whole brain analyses, and ROI analyses focused on frontal and temporoparietal structures previously reported to support speech production. Results showed substantial activation overlap between speech and non-speech function in regions. Although non-speech gesture production showed greater extent and amplitude of activation in the regions examined, both speech and non-speech showed comparable left laterality in activation for both target perception and production. These findings posit a more general role of the previously proposed "auditory dorsal stream" in the left hemisphere--to support the production of vocal tract gestures that are not limited to speech processing.

  • The left ventral premotor cortex is associated with generating the motor acts related to speech sounds, nonspeech sounds, and orofacial movements not associated with sound production.

    “while the left ventral premotor cortex was associated with generating the motor acts related to speech sounds (Ghosh et al., 2008; Peeva et al., 2010), nonspeech sounds (Chang et al., 2009) and orofacial movements such as tongue protrusion and lip pursing that are not associated with sound production (Price et al., 2011).”
  • Areas activated by speech are also activated by nonspeech orofacial movements and vocal tract gestures, sniffing, singing, volitional exhalation, and phonation.

    “As shown previously, the areas that are activated by speech were also activated by nonspeech orofacial movements and vocal tract gestures (Chang et al., 2009), sniffing (Koritnik et al., 2009), singing (Zarate et al., 2010), volitional exhalation and phonation (Loucks et al., 2007).”
  • In anterior cingulate, the most posterior zone is associated with motor execution rather than conflict monitoring or response selection, while the anterior zone associated with conflict monitoring is more activated by speech than nonspeech.

    “In the anterior cingulate, the most posterior zone was associated with motor execution, rather than conflict monitoring or response selection (Schulze et al., 2011) but the anterior zone associated with conflict monitoring (Schulze et al., 2011) was found to be more activated by speech than nonspeech (Chang et al., 2009).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
