摘要： 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; 32′a; 32b; 32′b) 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; 33′a; 33′b; 33′c) 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.
