本文介绍的视觉P300多功能刺激仪可提供三种符号构成的随机刺激序列,各符号的出现概率可调,与诱发电位仪联机可记录视觉P300。刺激仪同时给出平均反应时和击中靶的次数。
This article describes the visual P300 multi-function stimulator can provide three kinds of symbols consisting of random stimulation sequence, the probability of each symbol is adjustable, and evoked potentiometer online recordable visual P300. The stimulator also gives the average response time and the number of hits on the target.
