视诱发皮质电位VECP(visual evoked cortical potential)是刺激视觉发生的信号,在大脑皮层视区产生的电位变化,用作视路功能检查的方法,因其刺激条件多种多样,且个体差异又大,所以尚未用于临床诊断。然而,如严密地判定刺激条件,预料用VECP可以得到中心视功能的检查。众所周知,使用视角小的闪光刺激比视角大的刺激光会得 Visual evoked cortical potential (VECP) is a signal that stimulates visualization. The potential changes in the visual cortex of the cerebral cortex are used as a method of visual pathological examination because of the variety of stimulation conditions and large individual differences , So it has not been used for clinical diagnosis. However, if rigorous evaluation of the stimulus condition is expected with VECP, central visual function can be examined. As we all know, the use of a small perspective flash stimulation than the angle of the stimulating light will be obtained
