Abstract

The results suggest that low-threshold mechanoreceptive A#beta#-fibers are affected by antidromical electrical stimulation of the cutaneous nerve from an adjacent spinal segment, indicating that information transmission occurs between the two endings of peripheral afferent nerves from adjacent spinal segments without any involvement of the central nervous system, and that A#beta#-fibers are involved in the process of information intransmission between peripheral terminals from adjacent spinal segments.

Key words: Primary afferent A#beta#-fiber;Receptive field;Mechanoceptive threshold;Information transmission between peripheral terminals from adjacent spinal segments ;
