This study reveals two distinct brain pathways for vocalization. One involves the supplementary motor area (SMA) for programmed speech, while the other uses auditory feedback for speech acquisition.

Area of Science:

  • Neuroscience
  • Speech Science
  • Cognitive Science

Background:

  • Understanding the neural basis of speech production and perception is crucial for deciphering complex human communication.
  • Previous research has identified distinct brain regions involved in vocalization, but the interplay between motor and sensory speech centers requires further investigation.

Purpose of the Study:

  • To investigate the relationship between the motor and sensory speech centers in the human brain.
  • To delineate different cortical pathways involved in vocalization based on auditory feedback.

Main Methods:

  • Positron Emission Tomography (PET) was used to examine cortical activity in normal subjects.
  • Subjects perceived their own voice, which was altered to sound different from their articulated voice.

Main Results:

  • Significant activation was observed in the superior temporal gyri when subjects perceived altered auditory feedback of their own voice.
  • Absence of activity was noted in the supplementary motor area (SMA) under these conditions.
  • A previous study showed significant SMA activation with no superior temporal gyrus activity during simple vocalization.

Conclusions:

  • Two distinct cortical pathways for vocalization have been identified: a programmed pathway involving the SMA and a pathway utilizing auditory verbal feedback.
  • The SMA-mediated pathway is hypothesized to represent the mature system in adults.
  • The auditory feedback pathway may be associated with the process of speech acquisition.
