After a short description of the different premovement potentials it is suggested that readiness potentials (RPs) recorded over different cortical motor areas reflect different functions. Then it is proposed that the late wave of the contingent negative variation (CNV) is a composite of a RP and a stimulus preceding negativity (SPN). Arguments for the existence of a non-motoric SPN are given, based upon our recent experiments. Next, it is suggested that a SPN is found preceding at least three different kinds of stimuli. Finally, it is stated that motor preparation and stimulus anticipation are different processes, reflected in a different distribution of the accompanying Slow Waves and an all or none accompanying change in reflex amplitudes.
在简要描述了不同的运动前电位之后，有人提出在不同皮层运动区域记录到的准备电位（RP）反映了不同的功能。接着有人提出，关联负变化（CNV）的晚期波是RP和刺激前负电位（SPN）的复合体。基于我们最近的实验，给出了存在非运动性SPN的论据。接下来，有人提出在至少三种不同类型的刺激之前可发现SPN。最后指出，运动准备和刺激预期是不同的过程，这反映在伴随慢波的不同分布以及反射幅度的全或无伴随变化中。
