[Measurement of single action potentials of the dorsal nerve roots in the human].
The method of recording single unit potentials with wire electrodes in animals has been applied to humans. Using two pairs of special electrodes it was possible to record extracellular single unit potentials at two different places in nerve root filaments in the spinal canal with the dura open and to determine conduction velocities. This method may be used in the future for the identification of afferent fibres in the spinal canal during the operation.
