Working memory and neural oscillations: alpha–gamma versus theta–gamma codes for distinct WM information?

Highlights • We outline a framework for assigning distinct roles of theta/alpha/gamma-band oscillations to different WM-processes. • Gamma-band oscillations are actively involved in WM-maintenance. • Alpha-band activity underlies the inhibition of task-irrelevant activity. • Theta-band oscillations...

Zusammenfassung:	Highlights • We outline a framework for assigning distinct roles of theta/alpha/gamma-band oscillations to different WM-processes. • Gamma-band oscillations are actively involved in WM-maintenance. • Alpha-band activity underlies the inhibition of task-irrelevant activity. • Theta-band oscillations underlie the temporal organization of WM items. • Through cross-frequency coupling, alpha–gamma versus theta–gamma codes provide distinct mechanisms for different WM information.
