自闭症谱系障碍（ASD）是以社会交往障碍为特征的一种疾病。社会交往需要对他人的情感表达进行快速的处理和准确的认知。先前的电生理学研究试图阐明ASD患者对情绪面孔的非典型面孔特异性N170反应的过程。本研究探讨了ASD患者阈下情感启动对N170反应的影响，并对N170反应进行了时频分析。招募了15名参与者[7名ASD参与者和8名典型发育（TD）对照]进行实验。当参与者执行情绪面孔判断任务时，用128通道脑电图设备记录事件相关电位。结果显示，增强N170振幅阈上目标面对刺激时，他们之前的阈下恐惧面对刺激，在ASD和TD组。有趣的是，TD参与者在阈下恐惧面孔启动条件下，在N170时间窗内的右脸特定区域表现出更高的α-ITPC。相比之下，ASD组阈下恐惧和中性启动条件下ITPC在任何频带上均无显著差异。尽管ASD和TD组中N170成分的SAPEs存在共同特征，但ASD患者面部特定区域的异步锁相神经活动可能是ASD患者无意识面部处理受损的基础。
Autism spectrum disorder (ASD) is characterized by social communicative disturbance. Social communication requires rapid processing and accurate cognition regarding others’ emotional expressions. Previous electrophysiological studies have attempted to elucidate the processes underlying atypical face-specific N170 responses to emotional faces in ASD. The present study explored subliminal affective priming effects (SAPEs) on the N170 response and time-frequency analysis of intertrial phase coherence (ITPC) for the N170 in ASD. Fifteen participants [seven participants with ASD and eight typically developing (TD) controls] were recruited for the experiment. Event-related potentials were recorded with a 128-channel electroencephalography device while participants performed an emotional face judgment task. The results revealed enhanced N170 amplitude for supraliminal target-face stimuli when they were preceded by subliminal fearful-face stimuli, in both the ASD and TD groups. Interestingly, TD participants exhibited higher alpha-ITPC in the subliminal fearful-face priming condition in the right face-specific area in the N170 time window. In contrast, there were no significant differences in ITPC in any frequency bands between the subliminal fearful and neutral priming conditions in the ASD group. Asynchronous phase-locking neural activities in the face-specific area may underlie impaired nonconscious face processing in ASD, despite the presence of common features of SAPEs for the N170 component in both the ASD and TD groups.
