StereoEEG Motor Neuronal Potentials Decoding

"During the study session, the patient will sit at a table in front of a computer monitor. The stereoEEG electrodes will be connected to the Neurovisor-BMM52 electroencephalograph (Medical Computer Systems, Russia) and to a computer with a software for recording and decoding brain signals (BCI classifier). One microsensor (Ascension TrekStar, Ascension Technology, USA) and two disposable cutaneous electrodes (connected to the Neurovisor-BMM52 system) will be put on each patient's hand for electromyogram recording.~The session consists from 3 blocks (1-3). The participant is asked to:~1. execute simple motor tasks (thumbs up, open hand or clench hand into fist - 30 times with each hand with 5-second brakes), according to the instruction on the computer screen;~2. to imagine the same movements - 30 times with each hand with 5-second brakes;~3. to imagine the same movements with the feedback (brain-computer interface control).~The blocks are separated by 5-minute brakes."
