Identifying mediators of threat-aggression and experimental manipulation by tDCS (C07)

• Subject Area: Biological Psychiatry
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 512007073

C07 tests the interaction of the CS and frustrative non-reward as part of the NVS. It will investigate the electrophysiological correlates of frustrative feedback in aggression-prone patients. In the aftermath of induced stress, an EEG task-battery including frustrative feedback will be applied for extraction of error-related negativity (ERN) and contingent negative variation to monitor electro-physiologic signaling of the relevant learning and frustration processes. In half of the participants, tDCS over the prefrontal cortex will be applied to enhance cognitive control, with participants being put into a stress context inducing frustration.
