Which scientist expanded on Galvani's work?

• A. Alessandro Volta
• B. Luigi Galvani
• C. Giovani Aldini
• D. Michael Faraday

Answer: (C)

The idea being tested is how one scientist carried a discovery about electricity and muscles into broader study. Giovanni Aldini, Luigi Galvani’s nephew, expanded on Galvani’s work by pushing galvanism beyond frog legs and applying electrical stimulation to other animals and even human cadavers. His demonstrations showed that electrical currents could evoke muscle contractions in larger organisms, helping to popularize and extend the concept of bioelectricity. This direct continuation of Galvani’s observations laid groundwork for later physiology and neuroscience research. While Volta contributed a practical electrical source and challenged the animal-electricity interpretation, and Faraday advanced electromagnetism and electrochemistry, Aldini is the one who most directly built on Galvani’s ideas.
