Patent ID: 8116874

Claim:
A device, comprising: at least one electrode and/or at least one chip configured to stimulate cerebral neurons that have a pathological oscillatory activity with a period duration T; n contact points that are distributed over at least one electrode and/or over at least one chip and are configured to output electrical stimulus signals to the brain, where n≧2; a sensor configured to measure the pathological oscillatory activity of the cerebral neurons; a controller configured to drive the contact points to output the electrical stimulus signals in a succession of stimulation time periods during which the electrical stimulus signals are output and alternating pauses during which none of the contact points outputs electrical stimulus signals, wherein the sensor measures the pathological oscillatory activity of the cerebral neurons during one of the pauses and the controller lengthens the respective pause by the period duration T or an integral multiple of the period duration T when the pathological oscillatory activity of the cerebral neurons falls below a predetermined threshold value.
