Impulse pattern, innervation density and two point discrimination of skin and mucosal afferents in humans. Considerations for a sensory reinnervation of urinary bladder and anal canal in spinal cord lesions. IV (IV).


1. Single fiber action potentials (Ap's) were recorded with 2 pairs of wire electrodes from a coccygeal nerve root. Simultaneous impulse patterns of 3T0 + 6T1 + 3T2 + 11T3 + 5T4 and 4P single skin afferent units were separated by their different Ap wave forms and conduction velocities. For a rapid touch or pin-prick the afferent units fired on average with… (More)
