Galvani investigated of what seemed to be electricity in animal tissue. He later discovered a electric force that activated the muscles of dead animals. He thought the activation of the electrical force in the animal was generated from a electrical fluid coming from the nerves to send to the muscles. This physical act was known as galvanism. Any study of galvanic effects in biology today, is specified as electrophysiology. In his discoveries, it led to one of his inventions called a voltaic pole, used as a battery for a constant source of electricity. His experiment was placed in a historic part in bioelectromagnetics, as it confirmed that electricity is not direct.Galvani is known to be the first researcher to understand the connection between electricity and life.
