Resumo1. The stimulating effects of a number of cholinomimetic substances upon the stretch receptor neurones of three species of crayfish have been compared. The neurons were excited both by “muscarinic” and by “nicotinic” compounds. 2. The actions of both groups of cholinomimetics could be prevented by a muscarinic blocking agent (atropine) and by nicotinic blocking agents (hexamethonium and dihydro-β-erythroidine). 3. It was concluded that these neurones possess only a single type of cholinoceptive receptor. Although certain differences between the species of crayfish were observed, this conclusion is believed to be valid for all.
