How do synapses work?

Each neuron does not directly end on another neuron, there is a small gap between two neurons called a synapse. In order for an impulse to be generated in the next neuron, a chemical transmitter is released. This then diffuses across the small gap. Many drugs work by directly interfering with this synapses, they may block or mimic the actions of neurotransmitters.
