Summary Introduction

To determine: An experiment to test the hypothesis that acetylcholine is Loewi’s proposed vaghusstoff, using a heart (without its vagus nerve), some acetylcholine, and an acetylcholine receptor blocker.

Experimental studies by Loewi opened the doors for chemical neurotransmitter studies.
