The Electrical Era – Galvani, Volta, and the Dawn of Neurophysiology

An MVP version of Chapter 17 Volume 1 of the Neuroscience Edition

The late 18th and early 19th centuries revealed electricity as the nervous system’s language. Luigi Galvani (1737–1798) and Alessandro Volta (1745–1827) demonstrated electrical currents animate muscles and transmit signals, transforming the brain from mysterious organ to dynamic electrical network.

Picture Bologna 1780: Galvani hangs frog legs on brass hooks from iron railing. Thunderstorm; lightning flashes, legs twitch. Galvani hypothesizes “animal electricity.” His 1791 publication argues nerves/muscles contain innate electricity.

Volta challenges: twitch from dissimilar metals creating current. Invents voltaic pile (1800)—first battery, producing continuous current.

Volta’s battery enables experiments. Aldini applies current to corpses—limbs move, faces grimace—demonstrating electricity’s role in life.

Their work advanced neurology: electricity as nerve signal, brain electrical center. Paved way for EEG, nerve conduction studies.

Anecdote: Galvani’s frog legs inspiring continued experiments after his death—legacy of discovery.

As we approach 19th-century localization, Galvani and Volta highlight electricity’s role—foundation for understanding brain adaptability.
