EEG Analysis During Light Propofol Sedation

Summary

The hypothesis of this study is that propofol sedation does not affect the detectability of a movement intention in the EEG motor cortex signal. EEG signals will be recorded during the realization of intentional movements and movement intentions by the healthy volunteers, as well as during median nerve stimulation before and during propofol perfusion according to a target control infusion. (0 µg/mL; 0.5 µg/mL and 1 µg/mL).
