At any instant, the electroencephalogram can be classified as to (i) polarity and (ii) direction of change in polarity. This classification provides a way to measure coupling between cortical areas. The technique is simple, yet of wide potential utility for studying functional relationships between cortical areas. The results of applying this technique suggest how the potentials giving rise to the electroencephalogram may play a role in information processing in the central nervous system.
在任何时刻，脑电图都可以根据以下两点进行分类：（i）极性，以及（ii）极性变化的方向。这种分类提供了一种测量皮质区域之间耦合的方法。该技术简单，然而在研究皮质区域之间的功能关系方面具有广泛的潜在用途。应用该技术的结果表明，产生脑电图的电位可能在中枢神经系统的信息处理中发挥作用。
