" Synapses are part of the circuit that connects sensory organs, like those that detect pain or touch, in the peripheral nervous system to the brain. Synapses connect neurons in the brain to neurons in the rest of the body and from those neurons to the muscles. This is how the intention to move our arm, for example, translates into the muscles of the arm actually moving. Synapses are also important within the brain, and play a vital role in the process of memory formation, for example".
