Abstract

A system (10) and a method for deep brain stimulation are provided. The system (10) comprises a probe (11) and a processor (14). The probe (11) comprises an array of sensing electrodes (12) for acquiring signals representing neuronal activity at corresponding positions in a brain and an array of stimulation electrodes (12) for applying stimulation amplitudes to corresponding brain regions. The processor (14) is operably coupled to the sensing electrodes (12) and the stimulation electrodes (12) and is arranged for performing the method according to the invention. The method comprises receiving (21) the acquired signals from the sensing electrodes (12), processing (22) the acquired signals to find at least one brain region with atypical neuronal activity, based on the acquired signals determining (23) a spatial distribution of stimulation amplitudes over the array of stimulation electrodes (12), and applying (24) the spatial distribution of stimulation amplitudes to the array of stimulation electrodes (12) in order to stimulate the at least one region with atypical neuronal activity.

Description

technical field

[0001] The present invention relates to a system for deep brain stimulation comprising: a detector having an array of stimulating electrodes for applying stimulation amplitudes to corresponding brain regions; a processor for determining A spatial distribution of stimulation amplitudes and for applying the determined spatial distribution of stimulation amplitudes to the array of stimulating electrodes in order to stimulate at least one region with atypical neuronal activity.

[0002] The invention also relates to a method for determining a spatial distribution of stimulation amplitudes for deep brain stimulation and a computer program product for implementing said method. Background technique

[0003] Deep brain stimulation (DBS) is a technique that applies moderate electrical impulses to brain tissue to disrupt pathological activity. Existing DBS devices have four large (typically 6mm 2 ) cylindrical electrodes. This results in a very ambiguous delivery of...
