Results We find that for normal adult,the latencies evoked by square-wave checkerboard at periphery of four direction are getting longer and longer by increasing the space frequency,for the amplitud.
结果正常人的周边VEP在这4个方向上的N75、P100的潜伏期均随空间频率的增大而增大;N75-P100的峰值却有一个最适的空间频率,即N75-P100峰值只在这个最适空间频率下最大;另外周边区VEPN75、P100的潜伏期均较中央区VEPN75、P100的潜伏期明显延长,周边区VEPN57-P100的峰值均较中央区VEPN75-P100的峰值低。
