Real-time fMRI Neurofeedback
Schematic representation of the real-time fMRI (rt-fMRI) neurofeedback experimental procedure.
A) Baseline resting state (RS-pre) scan. B) Functional Localization of the default mode network (DMN) and the central executive network (CEN). C) rt-fMRI feedback process showing the online monitoring of brain states while performing “mental noting”. If rt-fMRI analysis resulted in a Positive Diametric Activity (PDA) score (red shadowing) the central white dot of the feedback display moved in the upper direction and towards the red circle. The contrary was the case when a negative PDA score was triggered (blue shadowing). D) Post rt-fMRI resting state.
