近十多年来,各方面对于疼痛进行了广泛的研究,取得了相当大的进展。因而,有必要在新的基础上,对疼痛这个问题进行一次回顾。本文准备介绍近年来有关疼痛的神经解剖和生理的一些实验资料和临床研究。一、痛觉的周围神经元是否存在对感受和传导痛觉具有特异性的周围神经元,在感觉生理上是一个长期争论的问题。受Muller特异能量定律影响的生理学者,认为痛是 In the past decade or so, various aspects of pain have been extensively studied and considerable progress has been made. Therefore, it is necessary to review the issue of pain on a new basis. This article is intended to introduce some of the experimental data and clinical studies on neuroanatomy and physiology of pain in recent years. First, the pain of peripheral neurons exist on the feeling and conduction of pain-specific peripheral neurons, in the sense of physiology is a long-standing controversy. Physiologists affected by Muller’s Law of Specific Energy think pain is
