摘要：

As part of stereotactic surgery, microelectrode recordings of somatosensory neurons in thalamus were obtained in 5 patients. Neurons with receptive fields on the lips and tongue were consistently activated when these structures were involved in production of speech sounds. The magnitudes of these responses were similar to those elicited by experimentally applied mechanical stimuli, suggesting that speech-induced somatosensory inputs are not suppressed at the thalamic level. © 1990.
