Details and patient eligibility

About

To measure the electric fields induced by DBS (deep brain stimulation) on the scalp and to improve electric field simulations, the investigators will measure EEG (electroencephalography) measurements with high sampling rates (>100 kHz). The investigators hypothesize that we can improve electric field simulations of DBS by validating and calibrating the simulations based on EEG measurements at high sampling rates (>100 kHz).

Enrollment: 20 estimated patients

EEG measurement during DBS

Description:

Different DBS conditions can include the individual bilateral therapeutical DBS settings, unilateral versions of these setting, unilateral single segment use of these settings or unilateral low frequency (15-30 Hz) DBS. EEG measurements with a 4-channel analog EEG amplifier (Digitimer EEG).

Treatment:

Other: EEG recording
