The auditory mismatch negativity (MMN) and P300 of event-related potentials were compared in normal children either with or without musical meditation training. The experimental group consisted of 11 subjects who had been trained with musical meditation for six months and the control group consisted of 12 subjects (matched for age, sex and grade) who had not received musical meditation. MMN amplitudes in the trained children were larger than those in the control group. In addition, the MMN amplitudes were identical in attend and ignore conditions for both groups. This evidence suggests that auditory brain function has been affected by musical meditation training. It thus suggests that the MMN is capable of assessing changes to the brain function in normal subjects. There were no significant differences in the P300 latencies and amplitudes between the two groups. This result suggests that MMN and P300 may reflect different aspects of the brain function.
对有或没有接受音乐冥想训练的正常儿童的事件相关电位中的听觉失匹配负波（MMN）和P300进行了比较。实验组由11名接受了六个月音乐冥想训练的受试者组成，对照组由12名（年龄、性别和年级相匹配）未接受音乐冥想训练的受试者组成。接受训练儿童的MMN波幅大于对照组。此外，两组在注意和忽略条件下的MMN波幅相同。这一证据表明音乐冥想训练影响了听觉脑功能。因此表明MMN能够评估正常受试者脑功能的变化。两组之间的P300潜伏期和波幅没有显著差异。这一结果表明MMN和P300可能反映了脑功能的不同方面。
