Device for locating the target spot of electrodes used for brain stimulation particularly deep brain stimulation

摘要

The invention relates to a device for locating the target spot of electrodes used for brain stimulation, particularly deep brain stimulation. The inventive device comprises an isolation amplifier (1) which is provided with at least one electrode (2) and at least one sensor (3). In a preferred embodiment, said device is provided with a control unit (4) which puts the signals of the electrodes (2) and the sensor (3) in relation and controls the input of stimuli via the electrode. In a particularly preferred embodiment, the stimuli are launched in a galvanically decoupled manner by optical means. The inventive device makes it possible to find the target spot for brain-stimulating electrodes in a particularly precise and fast manner according to objectifiable parameters.
