摘要
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。
An aided testing system for Producing a Paradigm consisting of three kinds of visual symbols with different Pseudo-random sequences and RT counting is Presented. The Probability of each symbol is adjustable. This system can be connected with an external trigger interface of evoked Potential recorder for research of ERPS. The average RT and the coun of hit targer stimuli are shown automatically.
