Fig. 2: Oscillatory activity systematized using BRAC.

Oscillatory activity in the theta, alpha, beta and gamma frequency band mapped on the mechanistic structure of the BRAC framework. Alpha band activity is likely to be central for top-down (i.e., attentional weighting/instruction-based processes) and bottom-up (i.e., experience-based processes/perception) modulatory effects on binding and retrieval processes. Theta band activity is thus directly modulated by alpha band activity, because theta band activity is supposed to reflect binding and retrieval processes impinging on event-files Gamma band activity is also part of this dynamics, especially as far as the encoding/retrieval of locally bound stimulus features underlying a coherent perception are concerned. Beta band activity is thought to be essential for constituting the event-file structure and is thus subject to theta/gamma band activity effects underlying binding and retrieval processes.
