EEG reactions in emotional face recognition were studied in five participants with Asperger syndrome (AS) and seven control subjects. Control subjects showed a spectral power increase following the stimulus onset in two time-frequency intervals-(1) 150-300ms in the 1-16Hz frequency range and (2) 300-650ms in the 1-8Hz range. Also, alpha/beta desynchronization occurred 400-1000ms after the stimulus onset with maximal amplitude in the posterior region. Theta synchronization (4-8Hz) was weaker in the AS group than in the control group, but beta2 desynchronization was stronger in the AS group. The results were interpreted in terms of automatic and voluntary control of perception.
对 5 名阿斯伯格综合征（AS）患者和 7 名对照组参与者的情绪面孔识别中的 EEG 反应进行了研究。对照组在两个时频间隔内显示出刺激开始后的频谱功率增加-(1) 150-300ms 频率范围为 1-16Hz，(2) 300-650ms 频率范围为 1-8Hz。此外，在刺激开始后 400-1000ms 出现 alpha/beta 去同步化，最大振幅在后区。与对照组相比，AS 组的 theta 同步化（4-8Hz）较弱，但 beta2 去同步化较强。结果从感知的自动和自愿控制的角度进行了解释。
