What is a synapse?
A synapse is the tiny gap between two neurones. At a synapse information is passed across the gap via chemicals, called neurotransmitters, rather than using electrical impulses. When information passes across the synapse, one neuron releases neurotransmitters which then diffuse across the gap. These then bind to the other neuron causing it to trasmit electrical impulses.
