Abstract
A method is described which permits simultaneous measurement of changes in slow electroencephalographic potentials (Contingent Negative Variation-CNV) and the excitability of the spinal monosynaptic arc (H reflex) during the foreperiod of a simple reaction time experiment. Data from 11 normal subjects show that during the development of the CNV there is an augmentation of the amplitude of the H-reflex. It is suggested that the two phenomena are controlled by a common subcortical structure.
摘要
本文描述了一种方法，该方法允许在简单反应时实验的预备期内同时测量慢脑电图电位变化（关联性负变 - CNV）和脊髓单突触弧兴奋性（H反射）。来自11名正常受试者的数据表明，在CNV发展过程中，H反射的波幅会增大。有人认为这两种现象受一个共同的皮层下结构控制。
