Presented live at FITC Amsterdam 2014 on Feb 24-25, 2014 More details can be found at www.FITC.ca Backyard Brains: Bringing the Body’s Electrical Signals Out of the Body with Timothy Marzullo Have you ever wondered how the electrical impulses of neurons and muscles work? Backyard Brains can help you understand! They have invented simple, portable electronics and microscopes to allow anyone to study neurons and muscles. With live demos and experiments on stage, you can do experiments that were previously only available in advanced research universities. Bring your brain!

- 4. The brain is complex because it is an electrochemical organ. El cerebro es complejo: es un órgano electroquímico.
- 5. El cerebro tiene células llamadas neuronas, que tienen largas ramificaciones conocidas como axones. El axón más largo viaja de tu espalda al dedo de tu pie. Entre cada axón existen sinapsis.
- 6. Como los axones son tan largos, y tu cerebro necesita ser rápido, éste usa pulsos eléctricos que viajan a través de los axones.
- 7. Este pulso eléctrico es provocado por iones moviéndose hacia adentro y afuera de las células. Este pulso se llama “spike”.

Editor's Notes
- PhD in Astro-physics
- Such discoveries led to debates at the time as to whether “animal electricity” was different from the electricity during lightning storms. Galvani also tested this by hanging frog legs off his back porch during thunderstorms & watching the legs twitch.
