摘要
在46名年龄从21～69岁的健康人中,就年龄对P300的影响,在视听两种模式下进行了对比研究。结果发现:视听两种模式所引出的事件相关电位(ERPs)之N_1、P_2、N_2成分的潜伏期与年龄的变化缺乏一致性,而P300成分的潜伏期则随年龄的增长而延长,延长的速率分别为1.56ms/年(听)和1.41ms/年(视)。两种模式之间的P300的潜伏期相关性分析发现:在健康人中,视听P300潜伏期的变化具有较好的一致性。
Among 46 healthy subjects aged from 21-69, a comparative study about the relationship between age and P300 in visual and auditory modalities was conducted. The results showed that the latency of P300 evoked by visual and auditory modalities both increased with age at 1. 56 ms/year versus 1. 41mg/year respectively. From the correlative analysis it was found there was a fine correlation in the latency of the P300 between auditory and visual modalites in the healthy subjects.
