The present invention relates to neurostimulation using electrical AC and/or DC stimulation pulses. The invention is particularly related to the area of brain and/or spinal cord stimulation of a patient by means of an implanted neurostimulation device. The present invention overcomes disadvantages and restrictions of the prior art by offering neurostimulation using AC and/or DC stimulation pulses combined with a safe operation in DC mode by discharging build-up loads at the interfaces of the electrodes through short circuiting such stimulation electrodes with a counter electrode, for example a common ground electrode. The positive effects and advantages of the invention are realized by a neurostimulation device, a method for brain neurostimulation and/or spinal cord neurostimulation, a computer program for controlling a neurostimulation device and the use of the aforementioned neurostimulation device for brain neurostimulation and/or for spinal cord stimulation.
