Salivary Secretion in Man Elicited by Means of Stimulation of the Chorda Tympani

Abstract

Abstract. During some operations on the ear in man the chorda tympani is exposed and become accessible to experiment. Electrical stimulation caused secretion of saliva, with maximal response at 10 impulses per sec and 2–3 V. iltropine abolished the response. Intravenous infusion of acetyl‐,6–methylcholine iodide some days after cutting the chorda tympani on onr side caused bilateral secretion of saliva while the response to lemon juice on the tongue was greatly reduced on the operated side.
