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:视听两模式所引出的ERPs之N1、P2、N2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/a(听)和1.41ms/a(听)。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 analysis was performed about the effect of aging on P300 between visual and auditory modalities.The results showed that only the latencies of P300 component evoked by visual and auditory modalities increased with aging at 1.56ms/a and 1,41ms/a respectively,From the correlative analysis of P300 latencies between the two kinds of modalities, it was found that a good consistence existed among them in the healthy subjects.
