The invention relates to a device for electrophysiologically localizing target areas in the brain, comprising a multi-channel microprobe (10) which at its active end comprises a multitude of tightly packed microelectrodes arranged axially in rows, via which electrophysiological efferences are obtained in the target area and forwarded to an evaluating unit, wherein the microprobe (10) is assigned to a tracking device (5) which allows the microprobe (10) to be positionally detected by means of a neuronavigation system (1, 2, 3, 8) and the insertion of the probe to be stereotactically planned.
