试评外周神经生理效应的函数之争

大量的神经生理学实验久已证实由刺激引起的外周神经生理效应具有类似于心理物理效应的高度压缩现象。从外周神经纤维中观察到的神经脉冲频率或发生电位是描述这种压缩效应的常用方法。半个多世纪以来一部分研究人员观察到压缩效应遵守刺激强度的线性对数函数，而另一部分研究人员则观察到幂函数。这种传统实验分歧，通过笔者前时建立的刺激一效应方程，得到合理的说明和两者的统一

A REVIEW ON THE CONTROVERSY OF PERIPHERALNEUROPHYSIOLOGICAL FUNCTION

Neurophysiological experiments since the 20s of this century have shown that the compression originally observed in psychological . experiments is also present in the pattern of peripheral neural activity. It is most usually measured in terms of the frequency of the train of the nervous impulses recorded at peripheral sensory neurons. Some investigators have found loguithmic neural function, while others have reported power function. This controversy of specific mathematical rule which best describes the compression has been discussed and unified in this paper by the application of the stimulus - effect model of the brain previously established by the author.
