Abstract

The invention relates to an electrode body (20) of an electrode assembly for electrically stimulating tissue of a living being, more particularly for neurostimulation. The electrode body (20) is designed to be arranged at a point between the skull and the scalp of a living being. The electrode body (20) has a stimulation surface, which is designed to be brought into contact with the tissue of the living being in order to produce an electrical stimulation of the tissue by alternating-current pulses and/or direct-current pulses. The electrode body (20) has a stimulation surface having an area of at least 50 mm2, a stimulation surface having an area of at least 20 mm2 and additionally a surface treatment which enlarges the effective stimulation surface, a fastening, structure for fastening the electrode body (20) to the tissue of a living being, a conductor connection point, by means of which the electrode body (20) can be connected, by soldering, adhesive bonding, welding or another connection technique, to an electrical conductor (4) for electrically connecting the electrode body (20) to an electrical device or another electrode body (20). Except for the stimulation surface, the ele…
