γ振荡现在被广泛认为是大脑功能相关的信号，这表明与事件相关的振荡的概念弥合了单个神经元和神经组件之间的差距。再进一步，我们回顾了实验，表明振荡现象（例如alpha，theta或Delta对事件的反应）与感觉和认知功能截然不同。这篇评论认为，通过大量神经元种群，有选择地分布了Delta，Theta，Alpha和Gamma振荡系统作为共鸣的通信网络。因此，振荡过程可能与记忆和集成功能有关。还提出了一种新的“神经元 - 脑”学说来扩展Sherrington的神经元学说。 （c）2000 Elsevier Science B.V.保留所有权利。
Gamma oscillations, now widely regarded as functionally relevant signals of the brain, illustrate that the concept of event-related oscillations bridges the gap between single neurons and neural assemblies. Taking this concept further, we review experiments showing that oscillatory phenomena such as alpha, theta, or delta responses to events are strongly interwoven with sensory and cognitive functions. This review argues that selectively distributed delta, theta, alpha, and gamma oscillatory systems act as resonant communication networks through large populations of neurons. Thus, oscillatory processes might play a major role in relation with memory and integrative functions. A new 'neurons-brain' doctrine is also proposed to extend the neuron doctrine of Sherrington.
