A short introduction is given to Thomas Laycock (1812-1876), and attention drawn to the development of neurological understanding in the nineteenth century. The main text describes a postulated part of the nervous system, the trophic, which was thought to govern nutritive functions of the body. Thomas Laycock appears as a lone figure in British medicine in giving serious consideration to a trophic nervous system. His discussions are based on clinical observations but his theories are speculative. He devised an instrument (an aesthesiometer) which he hoped would identify abnormalities of the trophic nervous system. The demise of a trophic nervous system is described with quotations from Charcot and Gowers and the use of the word trophic in current practice is mentioned.
本文简要介绍了托马斯·莱科克（1812 - 1876），并提请注意19世纪神经学理解的发展。正文描述了神经系统中一个假定的部分——营养性神经，它被认为控制着身体的营养功能。托马斯·莱科克在英国医学领域是一个独特的人物，他认真考虑了营养性神经系统。他的讨论基于临床观察，但他的理论具有推测性。他设计了一种仪器（一种触觉测量仪），希望能用它来识别营养性神经系统的异常情况。文中引用了夏科和高尔斯的话描述了营养性神经系统的衰落，并提及了“营养性的”这个词在当前医学实践中的使用。
