Abstract

An implantable electrode arrangement provides spatially-selective detection of neuronal electrical signals, which propagate along at least one nerve fiber contained in a nerve fascicle, and for selective electrical stimulation of the at least one nerve fiber, comprising a biocompatible carrier substrate, which has at least one carrier substrate region that can be placed around the nerve fascicle in a cuff and has a straight cylinder-shaped carrier substrate surface which faces the nerve fascicle in the implanted state. The carrier substrate surface has an axial extension and an extension oriented circumferentially in a direction and a first electrode arrangement attached thereto. The electrode arrangement comprises in an axial sequence, at least three first electrode structures with at least two first electrode surfaces arranged in the circumferentially, and at least two spaced first electrode strips, displayed in the axial direction which extend circumferentially which are in a ring shape, which encloses the at least three electrode structures on both sides in the axial direction. The electrodes are connectable or are connected to a signal detector and generator.
