Action potentials were recorded from the L7 or S1 dorsal root of the cat following stimulation of the peripheral end of the cut ventral root of the same segment. Conversely, action potentials were also recorded from the ventral root while stimulating the peripheral end of the cut dorsal root. Based on the conduction velocities of 52 single fibers, one-third were A delta-fibers and the remaining two-thirds belonged to the C-fiber category. These results suggest that there are both A- and C-fibers in continuity between the dorsal and the ventral root.
在刺激猫同一节段切断的腹根外周端后，记录L7或S1背根的动作电位。相反，在刺激切断的背根外周端时，也记录腹根的动作电位。根据52根单纤维的传导速度，三分之一是Aδ纤维，其余三分之二属于C纤维类别。这些结果表明，背根和腹根之间存在连续的A纤维和C纤维。
