Investigating the Effect of Normal Frequency-band and Infra-low Frequency Neurofeedback on Functional Brain Connectome

Real Neurofeedback with visual and acoustic feedback presentation based on the EEG-signal from the participant (Signals used described in corresponding study arm). The NFB-signals are obtained from the T4 and P4 positions according to the 10-20 EEG placement consensus. NFB is done using the software package Cygnet (BEE Medic GmbH Technologies, Kirchberg, Switzerland) and for all participants the same neurofeedback-animation is used. NFB training duration is approx. 30min

The sham neurofeedback is performed in identical fashion using the same software, feedback, electrode placement, duration as in the real neurofeedback. Only difference is that a pre-recorded EEG-dataset will be used and the feedback signal is thus independent from the brain activity of the participant.
