Abstract:
1. A method for determining a relation between stimulation settings for a brain stimulation probe and a corresponding V-field, the brain stimulation probe comprising multiple stimulation electrodes, the V-field being a potential distribution in brain tissue surrounding the stimulation electrodes, the method comprising: sequentially applying a test current to n stimulation electrodes, n being a number between 2 and the number of stimulation electrodes of the brain stimulation probe; for each test current at one of the n stimulation electrodes, measuring a resulting excitation voltage at m stimulation electrodes, m being a number between 2 and the number of stimulation electrodes of the brain stimulation probe; from the stimulation settings and the measured excitation voltages, deriving an (m*n) coupling matrix having m lines and n columns, an entry Z using the coupling matrix for determining the relation between the stimulation settings and the corresponding V-field.
