Discuss how Dr. Loewi was able to determine that communication between neurons involved a chemical messenger.

What will be an ideal response?


Dr. Loewi performed an experiment where he stimulated a frog heart. As a result, the heart beat would slow down. He collected the fluid that the first heart was sitting in and applied it to a second heart. The second heart also began to have a slower heart beat. He repeated this experiment but increased the heart rate of the first heart. He found that the second heart also increased the rate. He concluded that chemical must have been released into the fluid that was subsequently stimulating the second heart.
