Answer: Galvani used electrical current to study muscle contraction in the frog. Muller argued
for the use of experimental methods to study physiology. Helmholtz developed methods and
techniques to study the physiology of vision and audition. Flourens developed the technique of
experimental ablation, which can provide insight into the functions of brain regions.
