System and a method for controlling selective nerve stimulation of neural tissue of a subject

A system for controlling selective stimulation of neural tissue of a subject, said system comprising:

• a first electrode arrangement, comprising a plurality of electrodes, wherein different electrodes of the plurality of electrodes are configured to be arranged in different electrode locations in relation to a first longitudinal position of the neural tissue;
• a second electrode arrangement, comprising at least one electrode and configured to be arranged at a second longitudinal position of the neural tissue;
• and
• a stimulation signal generating unit,
• wherein the stimulation signal generating unit is configured to generate a first intermittent current waveform comprising a first pulse and a second intermittent current waveform comprising a second pulse, wherein the first pulse comprises a first frequency and the second pulse comprises a second frequency, wherein the second frequency is different from the first frequency,
• wherein the stimulation signal generating unit is configured to output the first intermittent current waveform to a first pair of electrodes of the first electrode arrangement and the second intermittent current waveform to a second pair of electrodes of the first electrode arrangement, thereby causing interferential stimulation of a plurality of nerve fibers of the neural tissue, wherein the interferential stimulation of each of the nerve fibers of the plurality of nerve fibers is configured to activate stimulation of the nerve fiber at a specific time point, thereby initiating propagation of signals through the neural tissue towards the second longitudinal position,
• wherein the stimulation signal generating unit is configured to generate a blocking pulse and to output the blocking pulse to the at least one electrode of the second electrode arrangement, thereby temporally selectively blocking propagation of signals through the neural tissue at the second longitudinal position.
