How does a synapse work bbc bitesize
WebStimulants and depressants affect the synapses between neurones in the nervous system: stimulants cause more neurotransmitter molecules to diffuse across the synapse depressants stop the next neurone sending nerve impulses – they bind to the receptor molecules it needs to respond to the neurotransmitter molecules. Tobacco and Smoking WebSynaptic transmission is the process at synapses by which a chemical signal (a transmitter) is released from one neuron and diffuses to other neurons or target cells where it generates a signal which excites, inhibits or modulates cellular activity.
