摘要：
Described here is an implantable electrode arrangement for spatially-selective detection of neuronal electrical signals, which propagate along at least one nerve fibre contained in a nerve fascicle, and for selective electrical stimulation of the at least one nerve fibre, comprising a biocompatible carrier substrate (1), which has at least one carrier substrate region that can be placed around the nerve fascicle in a cuff-like manner and has a straight cylinder-shaped carrier substrate surface (1) oriented facing the nerve fascicle in the implanted state, said carrier substrate surface having an axial (a) extent and an extent oriented in the circumferential direction (U) and a first electrode arrangement (2) being attached thereto, said electrode arrangement comprising, in an axial sequence, at least three first electrode structures (3) with in each case at least two first electrode surfaces (4) arranged in the circumferential direction and at least two first electrode strips (5), which are spaced apart from one another in the axial direction, extend in the circumferential direction and in each case assume a ring shape, said first electrode strips enclosing the at least three electrode structures on both sides in the axial direction, and being connectable or connected to a signal detector and generator (6). The invention is distinguished by virtue of the fact that at least one second electrode arrangement (7) is arranged next to the first electrode arrangement (2) in the axial sequence on the straight cylinder-shaped carrier substrate surface (1) facing the nerve fascicle, said second electrode arrangement comprising -at least two second electrode strips (8) which are axially spaced apart from one another, extend in the circumferential direction (U) and in each case assume a ring shape, and -at least one second electrode structure (13), extending axially between the at least two second electrode strips (8), in each case comprising at least two second electrode surfa
