Event-related potentials (ERPs) to synthetic consonant-vowel syllables were recorded. Infrequent changes in such a syllable elicited a "mismatch negativity" as well as an enhanced N100 component of the ERP even when subjects did not pay attention to the stimuli. Both components are probably generated in the supratemporal auditory cortex suggesting that in these areas there are neural networks that are automatically activated by speech-specific auditory stimulus features such as formant transitions.
记录了对合成辅音-元音音节的事件相关电位 (ERPs)。即使受试者没有注意到刺激，这种音节的不频繁变化也会引起“失匹配负波”以及 ERP 的 N100 成分增强。这两个成分可能都在前颞叶听觉皮层中产生，表明在这些区域存在神经网络，这些神经网络会自动被语音特定的听觉刺激特征（如共振峰转换）激活。
