Transmission abolished on a cholinergic synapse after injection of acetylcholin-esterase into the presynaptic neurone

Abstract

SINCE electron microscopy has enabled the identification of vesicles which appear concentrated at anatomically defined synaptic sites, a theory has been proposed that the transmitter released at the synapses is of vesicular origin. The synaptic vesicles had a high content of acetylcholine (ACh)1–3 and were ideal carriers of ‘packets’ of ACh released at the synapse, a necessary requirement for the quantal theory of transmission4.
