Satisfactory BTEP waveforms were recorded in all of 50 subjects. The values of peaklatency and interpeak latency were approximate to the values of literatures.
结果:50例正常人均记录到满意的BTEP反应波,其峰潜伏期、波间期值与文献资料近似。

In each group, the N1 wave and P1 wave amplitude density were higher and peaklatency was longer in the upper retina than in the lower, there was no difference between nasal and temporal retina.
CONCLUSION: the prolongation of P300 peaklatency reflects the pathological changes of brain areas associated with cognitive function and the degree of cognitive function disorder in VD patients.
