Cross-frequency coupling between neuronal oscillations

Trends Cogn Sci. 2007 Jul;11(7):267-9. doi: 10.1016/j.tics.2007.05.003. Epub 2007 Jun 4.


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.
