September 9, 1737, in Bologna, Italy, Luigi Galvani is born, who will decipher the electrical nature of the nerve impulse.

On this day (September 9), 1737, in Bologna, Italy, Luigi Galvani was born, who would decipher the electrical nature of the nerve impulse.
Around 1755, Galvani entered the Faculty of Arts at the University of Bologna. Galvani attended the medical course, which lasted four years. Another discipline that Galvani learned along with medicine was surgery. He learned the theory and practice. In 1759, Galvani graduated in medicine and philosophy.
Galvani then became interested in the field of "medical electricity". This field emerged in the mid-18th century, following electrical research and the discovery of the effects of electricity on the human body.
The beginning of Galvani's experiments with bioelectricity has a popular legend that Galvani was slowly skinning a frog on a table where he and his wife had been conducting experiments with static electricity by rubbing the skin of the frog. frog. Galvani's assistant touched an exposed sciatic nerve of the frog with a metal scalpel that had picked up a charge. At that moment, they saw sparks and the dead frog's leg kicked as if it were alive. The observation made the Galvanis the first researchers to appreciate the relationship between electricity and animation, or life. This finding provided the basis for the new understanding that the impetus behind muscle movement was electrical energy carried by a liquid (ions), and not air or fluid as in previous hot-air balloon theories.
Volta, a professor of experimental physics at the University of Pavia, was one of the first scientists to repeat and verify Galvani's experiments. At first, he embraced animal electricity. However, he began to doubt that the conductions were caused by specific electricity intrinsic to the animal's legs or other body parts. Volta believed that the contractions depended on the metal cable that Galvani used to connect nerves and muscles in his experiments.
As a curiosity, comment that theGalvani's name also survives as a verb in everyday language (galvanize), as well as in more specialized terms: galvanic cell , Galvani potential , galvanic corrosion , galvanometer , galvanization and galvanic skin response .

- what's for lunch?
- frog legs
- frog legs?
- are you sure they are alive?
- I think so
- let's see...
- what are you doing?
- Oops! the haunch has jumped!
- aaaaaaaahhhhh!
- Hey! Waiting! It was a joke!
- aaaaaahhhhhh!
- I put electricity on it to make the muscles move
- aaaaahhhhh!
- it was an experiment!
- aaaaaahhhhh!
