1. A method for controlling a plurality of stimulation electrodes of a neurostimulation system that are arranged in an array, the method comprising:
- a) implanting the plurality of stimulation electrodes into brain tissue;
b) generating a sequence of electrical pulses using at least one pulse generator; and
c) sequentially distributing each pulse of the sequence of electrical pulses one at a time to different subsets of stimulation electrodes,wherein each subset of stimulation electrodes includes a plurality of the plurality of stimulation electrodes.

Abstract
The invention relates to a neurostimulation system, particularly for deep brain stimulation (DBS), comprising a spatial array (130) of stimulation electrodes (132) and an associated controller (110). The controller (110) is adapted to sequentially supply electrical pulses to different subsets of the stimulation electrodes (132). Preferably, the controller (110) comprises a single pulse-generator (112) and a multiplexing unit (111) for distributing the pulses to different stimulation electrodes. The stimulation electrodes (132) may preferably be arranged on probes (131).
