WebThere is a small gap between the two neurones called a synapse. In order for an impulse to be generated in the next neurone, a chemical transmitter is released. This then diffuses across the small gap. Many drugs work by interfering with synapses. They may block or copy the action of neurotransmitters in certain neurones.
