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!

Bringing the Body’s Electrical SignalsOut of the Body

The brain is complex because it is an electrochemical organ.

El cerebro es complejo: es un órgano electroquímico.

El cerebro tiene células llamadas neuronas, que tienen largasramificaciones conocidas como axones. El axón más largo viaja de tu

espalda al dedo de tu pie. Entre cada axón existen sinapsis.

Como los axones son tan largos, y tu cerebro necesita serrápido, éste usa pulsos eléctricos que viajan a través de losaxones.

Este pulso eléctrico es provocado por iones moviéndose haciaadentro y afuera de las células. Este pulso se llama “spike”.
