A method for suppression of seizures, and a related neurological stimulation device

Abstract

Disclosed is a method, performed by a neurological stimulation device, for suppression of seizures. The method comprises obtaining a first input signal indicative of a local field potential. The method comprises obtaining a plurality of target frequencies including a primary target frequency and a secondary target frequency for neurological stimulation. The method comprises filtering the first input signal based on the primary target frequency and the secondary target frequency for provision of a primary filter output signal and a secondary filter output signal. The method comprises determining a first primary delay and a second primary delay based on the primary target frequency. The method comprises determining a first secondary delay and a second secondary delay based on the secondary target frequency. The method comprises generating, based on the primary filter output signal, the secondary filter output signal, the first primary delay, and the first secondary delay, a first stimulation signal for a first stimulation electrode of a plurality of electrodes. The method comprises generating, based on the primary filter output signal, the secondary filter output signal, the second primary delay, and the second secondary delay, a second stimulation signal for a second stimulation electrode of the plurality of electrodes, and outputting the first stimulation signal to the first stimulation electrode and the second stimulation signal to the second stimulation electrode.
