The multi-scale characteristics of the absence seizure was shown in the rhythmitic activities of Scale 12 (frequency corresponding to 3 Hz). Their EEG signals 10 s before and after onsets have been different from the normal.

• 研究显示儿童失神癫?发作过程中脑电信号的多尺度典型特征主要表现为12尺度(对应频率3 Hz)的节律性活动显著增强；发作时20尺度(低频大尺度；对应频率0.；12 Hz)结构与频率3 Hz的结构具有非正常的跳跃式尺度关系；3 Hz节律性棘慢复合波与大尺度(频率1 Hz以下)背景低频放电结构共同存在。
