The present invention relates to an electrode (30, 30) for implantation in contact with a neural tissue, said electrode extending along an axis, said neural tissue being capable of generating one or more action potentials, and said one or more action potentials propagating with a given speed in said neural tissue. The electrode comprises a carrier (31, 31) of biocompatible electrically insulating material stimulation electrode contacts (32a 32a 32b 32b) deposited on a surface of said carrier (31, 31) for applying an electrical stimulation to said neural tissue so as to generate, after a given latency time, a compound action potential when stimulated by said electrical stimulation one or more sensing electrode contacts (33a 33b 33c 33a 33b 33c) deposited on said surface of said carrier and provided at a distance from said stimulation electrode contacts, said sensing electrode contacts being adapted to be connected to measuring means (23) having a given inactive period. The invention includes means to reduce the stimulation artifact. The invention also relates to an apparatus (20) and method for using various signals obtained from the stimulation probe itself and used to control the parameters of the current pulses applied to the electrodes.La présente invention concerne une électrode (30, 30) pour une implantation en contact avec un tissu neuronal, ladite électrode sétendant le long dun axe, ledit tissu neuronal étant capable de générer un ou plusieurs potentiels daction, et le ou les différents potentiels daction se propageant à une vitesse donnée dans ledit tissu neuronal. Lélectrode comprend un support (31, 31) de matériau biocompatible isolant de lélectricité des contacts délectrode de stimulation (32a 32a 32b 32b), déposés sur une surface dudit support (31, 31), pour appliquer une stimulation électrique audit tissu neuronal de façon à générer, après un temps de latence donné, un potentiel daction composite lors dune stimulation par ladite stimulation électri
