Neuromuscular function was decreased in aged rats and GDNF improved the function. a Samples of the CMAPs recorded in the adult group, aged group, aged + NS group and aged + GDNF group. Compared to the adult group, the amplitude was decreased in the aged group (b), the duration, nerve conduction velocity and latency period were increased in the aged group (c, d, e). The treatment of GDNF increased amplitude and decreased the duration, nerve conduction velocity and latency period. Values are shown as mean ± SD (n = 10, **P < 0.01)
