Abstract
A device including 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, and a controller configured to drive the contact points so that the contact points output a low-frequency succession of sequences of high-frequency pulse trains to the brain, wherein, for each sequence, m contact points of the n contact points are selected, with m≧2 and m<n, and high-frequency pulse trains are applied only via the selected m points, and the temporal shift between two successive high-frequency pulse trains that are applied by different contact points is T/m.
