    Abstract

    Computation of field potentials and activating functions in an infinite, homogeneous medium was carried out as a first approach to investigating the effect of several electrode combinations on nerve fibers with different orientations in the spinal cord. The cervical spinal cord and its surrounding tissues were then modeled as an inhomogeneous, anisotropic volume conductor. It was concluded that cathodal stimulation, medio-dorsally in the epidural space, can recruit longitudinal fibers, but may block dorso-ventral ones. With anodal stimulation the opposite will occur. The main parameters that effect the potential distribution in the dorsal columns are the width of the subarachnoid space and inhomogeneities in the epidural space near the electrodes.
