Electrophysiological recordings in animals, including humans, are modulated by oscillatory activities in several frequency bands. Little is known about how oscillations in various frequency bands interact. Recent findings from the human neocortex show that the power of fast gamma oscillations (30-150Hz) is modulated by the phase of slower theta oscillations (5-8Hz). Given that this coupling reflects a specific interplay between large ensembles of neurons, it is likely to have profound implications for neuronal processing.
包括人类在内的动物的电生理记录受到多个频段振荡活动的调节。关于不同频段的振荡如何相互作用，目前知之甚少。来自人类新皮层的最新研究结果表明，快速伽马振荡（30 - 150赫兹）的功率受到较慢的theta振荡（5 - 8赫兹）相位的调节。鉴于这种耦合反映了大量神经元群体之间的特定相互作用，它可能对神经元处理具有深远影响。
