猴对嗓声的识别及其听觉平均诱发电位

VOICE RECOGNITION AND AUDITORILY-EVOKED POTENTIALS IN MONKEYS

本文研究了六只猴在识别嗓声中的听觉平均诱发电位(AEP)。熟悉人的有声辅音音节“ba”在右颢区比无声辅音音节“pa”引出高幅N200波,但陌生人嗓声“pa”却比“ba”在左颞区引出高波幅N200波。熟悉人“ba”音比熟悉猴“er”音在两颞区引出的P300波潜伏期长。这些结果说明猴的AEP 可客观地反映出熟悉人与陌生人,熟悉人与猴嗓声的差异.

The auditorily-evoked potentials(AEP)were studied in six monkeys during voicerecognition. The amplitudes of N200 wavesevoked by a familiar human's syllable withvoiced consonant “ba” were higher than thoseby a familiar human's syllable with voicelessconsonant“pa”in the right temporal area,butthe amplitudes of N200 waves evoked by anunfamiliar human's“pa”were higher thanthose by an unfamiliar human's“ba”in theleft temporal area.The latencies of P300 wavesevoked by a familiar human's voice werelonger than those by familiar monkey's voice.The results suggest that AEPs are sensitiveto familiar and unfamiliar human's voices,and familiar human's and monkey's voices.
