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.
伽马振荡如今被广泛视为大脑中具有功能相关性的信号，这表明事件相关振荡的概念弥合了单个神经元与神经集合之间的差距。进一步拓展这一概念，我们回顾了一些实验，这些实验表明诸如对事件的阿尔法、西塔或德尔塔反应等振荡现象与感觉和认知功能紧密交织。本综述认为，选择性分布的德尔塔、西塔、阿尔法和伽马振荡系统通过大量神经元起到共振通信网络的作用。因此，振荡过程可能在与记忆和整合功能相关方面发挥主要作用。还提出了一种新的“神经元-大脑”学说以扩展谢灵顿的神经元学说。
