We investigated the MMN at electrode Fz to 12% temporally predictable or unpredictable duration decrement deviant stimuli in 29 healthy controls and 31 schizophrenia patients. With a stimulus onset asynchronicity of 500 ms in the regular predictable condition, a deviant occurred every 4 s while it varied randomly in the unpredictable condition. Here we report detailed data tables and multivariate analysis of variance results (MANOVA) on MMN, P3a and standard ERP data including details on follow-up analyses. An extended figure shows MMN difference curves and averages to standard and deviant stimuli in both experimental conditions and subject groups.
我们在29名健康对照者和31名精神分裂症患者中，研究了电极Fz处对12%时间上可预测或不可预测的时长递减偏差刺激的失匹配负波（MMN）。在常规可预测条件下，刺激起始异步性为500毫秒，每4秒出现一次偏差刺激，而在不可预测条件下，偏差刺激随机出现。在此，我们报告关于MMN、P3a和标准事件相关电位（ERP）数据的详细数据表及多变量方差分析结果（MANOVA），包括后续分析的详细信息。一张扩展图展示了两种实验条件和受试者组中，MMN对标准刺激和偏差刺激的差异曲线及平均值。
