Evoked Potential Recording During DBS Surgery

"In addition to standard micro electrode recordings, we propose to measure:~1. surface potentials at the scalp (EEG) evoked by stimulation at the DBS electrode site~2. micro electrode potentials at the DBS electrode site evoked by stimulation at the median and tibial nerves~3. local field potentials at the DBS electrode site evoked by stimulation at the median and tibial nerves~4. surface EMG in the first dorsal interosseus and gastrocnemius muscles during stimulation at the DBS electrode site."
