Subject's own speech reduces reactivity of the human auditory cortex

Numminen, Jussi, Salmelin, Riitta, Hari, Riitta·1999·Neuroscience Letters

Abstract

Previous studies on monkeys have shown that uttering-related cortical areas exert an inhibitory effect on the auditory cortex, and cerebral blood-flow analyses on humans have revealed modulation of the activity of the auditory cortex during own speech. To study this modulation on a millisecond time scale, we recorded neuromagnetic evoked responses to short 1-kHz tones while the subjects were reading silently and aloud. The 100-ms response (M100) of the auditory cortex was delayed by 10-21 ms and its amplitude was dampened by 44-71% during reading aloud compared with reading silently. This effect was more prominent in responses to ipsilateral than contralateral tones, possibly due to a sum effect of diminished ipsilateral input to the cortex and decreased transcallosal excitation.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Speaking aloud reduces responses to sounds presented at the same time, and this suppression has been interpreted as evidence for auditory efference copies.

    “overt speech usually has dampening effects on simultaneously presented auditory stimuli (Numminen et al., 1999; Curio et al., 2000; Houde et al., 2002), and such speaking-induced response suppression has been argued to point to auditory efference copies.”

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.
