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.
