Luigi Galvani was an Italian scientist who, during the 1780s, discovered a relationship between electricity and the nervous system when he observed that an electric current applied to a dead frog caused the animal's legs to twitch. His primary discovery occurred in 1780, with additional work throughout the decade.
Luis Galvani worked at the University of Bologna, where he began his experiments with bioelectricity. His primary work on he subject, "De viribus electricitatis," was published in 1791. After Galvani's death, his work was continued by the scientist Allesandro Volta, who used it to invent the early battery. Galvani's work also provided early research in the fields of neurophysiology and neurology.Learn More
