Gamma Activity Coupled to Alpha Phase as a Mechanism for Top-Down Controlled Gating

Miller Lab

Bonnefond and Jenson used MEG in humans to find coupling between alpha and gamma rhythms during an attention-demanding task.  High alpha power was associated with weak gamma power at the trough of the alpha cycle.  This may provide a mechanism for top-down control of attention.
