The invention relates to an autonomous neurostimulation unit used in the modulation of the nervous system and which comprises: at least one pair of pads (1), each formed by at least one inner layer (11) of ceramic； an intermediate layer (2)； and a conductive alloy coating (3). The material of the layer of coating (3) is different and has different conductivity in each of the pads (1) of the pair. The unit can be used in the modulation of the nervous system, with neurostimulation methods that are adapted to each patient.
