There is a close relationship between perception and the production of language. In order to examine that of the central nervous system in the brain, a PET study was performed on healthy adults. The auditory association area, the Broca's area, was extensively activated during listening to speech. Neural activity was also observed in the cerebellum, in addition to Broca's area, motor area, and the supplementary motor area during reading aloud with auditory feedback. However, little activity in the auditory association area was noted compared with that during passive listening. These results suggest that one's own speech is not processed for perception by the auditory association area during speaking. During reading aloud with distorted feedback of input speech, activity increased in the auditory association area and in the motor area but was reduced in the supplementary motor area. Through these observations, we have found two different speech modes; feedforward control managed primarily by the supplementary motor area and feedback control by the auditory association area. It is suggested that interactions among functional areas of the brain for speech take place through numerous trial and errors during the language acquisition period and while the neural network is established. A PET study on patients with various functional voice disorders was also performed. It showed distinct differences in the activities of functional areas compared with those of healthy adults. Investigation of central cortical processing in the brain is important to elucidate the pathogenesis of patients with hearing and speech disorders.
