Resting membrane potentials (RMPs) have been recorded in vitro near the end-plate region of rat soleus muscles reinnervated with tetrodotoxin-inactive nerves and compared with those of denervated muscles whose reinnervation had been prevented. The two muscle groups exhibited the same low values of RMP typical of denervated muscles. In control muscles of rats in which impulse conduction was left unimpaired, reinnervation induced the expected increase in RMP values towards normal. It is suggested that, at least for this property, reinnervation restores to normal the muscle fibre membrane essentially through the return of activity.

Abstract

Resting membrane potentials (RMPs) have been recorded in vitro near the end-plate region of rat soleus muscles reinnervated with tetrodotoxin-inactive nerves and compared with those of denervated muscles whose reinnervation had been prevented. The two muscle groups exhibited the same low values of RMP typical of denervated muscles. In control muscles of rats in which impulse conduction was left unimpaired, reinnervation induced the expected increase in RMP values towards normal. It is suggested that, at least for this property, reinnervation restores to normal the muscle fibre membrane essentially through the return of activity.
