The present study shows that an infrequent vowel ('deviant') presented among frequent vowels ('standard') elicits in sleeping human newborns a negativity in the auditory event-related potential (ERP) resembling the mismatch negativity (MMN) recorded in adults. Thus, the MMN appears to provide means to investigate brain mechanisms of vowel perception in infants.
本研究表明,在频繁出现的元音(“标准”)中呈现一个不常见的元音(“偏差”),会在睡眠中的人类新生儿的听觉事件相关电位(ERP)中引发一种负波,类似于在成年人中记录到的失配负波(MMN)。因此,MMN似乎为研究婴儿元音感知的大脑机制提供了手段。
