Abstract:The number uf afferent fibers in a peripheral
nerve fascicle and the electrical volume conduction in neuraI
tissue determine the interelectrode spacing, needed for
selective recording with mufticontact devices. These factors
taking into account, and also assuming uniform distribution of
fibers throughout the fascicle cross section, it is calculated that
for selective sensing in peroneal nerve fascicles, the electrode
spacing must be about 80 pm. This is for the nelve, embedded
in its natural saline environment. The selectivity, thus reached,
however reduces dmstically to zero when an insulating cuff is
positioued around the nerve at the position of the intraneural
multielectrode device.
