BP是Kornhuber & Deecke （1964; Kornhuber & Deecke 1965）在头皮上放置电极录音时发现的。在此期间，准确地说，这种地面记录是测量BP的最常用手段，并有助于提供有关运动相关电位的关键信息。本章的第一个目的是研究影响BP振幅、坡度或地形的因素。其次，我将考虑哪些关于bp地形的信息可以帮助我们了解皮质运动区域的功能组织。第三，脑电位的表面记录显示运动开始前后的一个复杂的时空模式。本文将讨论它们的电生成和功能意义。在本章的最后一部分，我将回顾支持和反对BP不同组成部分的证据。
The BP was discovered by Kornhuber & Deecke (1964; Kornhuber & Deecke 1965) during recordings made from electrodes placed over the scalp. In the intervening years, it is probably accurate to say that such surface recordings have been the most common means of measuring the BP and have been instrumental in providing key information about this movement-related potential. A first aim of this chapter is to examine the factors that influence the amplitude, slope or topography of the BP. Secondly, I will consider what information about BP-topography can contribute to our knowledge of the functional organization of cortical motor areas. Third, surface recordings of the brain potentials show a complex, spatio-temporal pattern shortly before and after movement onset. Their electrogenesis and functional significance will be discussed. In the final part of this chapter, I will review the evidence for and against separate components of the BP.
