The electrical circuit of your body works thanks to tiny cells called neurons.

Neurons are a part of the nerves, brain, and spinal cord, and they work together to carry messages all over your body.

Each neuron talks to the others through special connections called synapses. For this talk, they use a secret language made of tiny electrical and chemical signals.

Every synapse helps control something important, like thinking, eating, moving your arms, and so much more!
