• Conditions: Psychogenic Seizure; Health, Subjective; Epilepsy, Temporal Lobe

• Registration Number: NCT05214833
• Lead Sponsor: ETH Zurich

Brief Summary

This study investigates whether the sense of agency is sensitive to self-regulation by means of EEG-based neurofeedback. During neurofeedback, the brain activity in response to a motor task is recorded in real-time and displayed back to the participants. The participants can therefore use this information to adapt their performance on the motor task.
