An electrophysiological analysis of the synthesis of acetylcholine in preganglionic nerve terminals

Abstract
1. An electrophysiological analysis has been made of the synthesis of acetylcholine (ACh) in the preganglionic nerve terminals of the isolated superior cervical ganglion of the guinea-pig. The mean amplitude of excitatory post-synaptic potentials recorded intracellularly was taken as a measure of the ACh output per impulse from the terminals of a preganglionic axon.
