The PINV has been widely applied to psychiatric investigations in which the definition of its abnormality depended on the visual evaluation without giving attention to its wave form. We have developed a new method of evaluating the PINV by applying the exponential regression correlation to raw and smoothed PINVs for the amplitude of the 15 points at the intervals of 70 msec. The significant correlation between the PINV wave form and the exponential curve was observed both in the raw and smoothed PINVs. Coefficient A was positively correlated with the PINV duration quantified by a visual measurement. Coefficients A and B had the negative and positive correlation with the CNV magnitude. The findings obtained in 28 healthy subjects suggest that the PINV may correlate to the CNV magnitude.
正相诱发电位（PINV）已广泛应用于精神病学研究，其中其异常的定义依赖于视觉评估，而未关注其波形。我们开发了一种新的评估PINV的方法，即将指数回归相关性应用于原始和平滑后的PINV，以分析间隔70毫秒的15个点的振幅。在原始和平滑后的PINV中均观察到PINV波形与指数曲线之间存在显著相关性。系数A与通过视觉测量量化的PINV持续时间呈正相关。系数A和B与关联性负变（CNV）幅度分别呈负相关和正相关。在28名健康受试者中获得的研究结果表明，PINV可能与CNV幅度相关。
