When we discussed the work of Galvani and Volta, we noted that Galvani's work was not fully appreciated until the development of instruments capable of detecting and amplifying the small biopotentials present in living organisms. Think about the cell models we have discussed in this course, and the experimental work of researchers like Hodgkin and Huxley. Describe an experiment that Galvani could have performed to help convince physicists like Volta of the existence of "animal electricity."
