PDF-DOPAMINE RECEPTORS DOPAMINE RECEPTORS It was not until the late s that dopamine was recognised

Interest in dopamine was intensified by the realisation that dopamine had an important role in the pathogenesis or drug treatment of certain brain History diseases eg Parkinsons disease schizophrenia This lead to much research on the sites of action.

The function of neurotransmitters. What is this?. What does it do?. Where are the neurotransmitters?. Can you name any neurotransmitters?. Neurotransmitter molecules are released from the end of the presynaptic cell (the axon) into the space between the two nerve cells (the synapse). Having travelled across the synaptic gap or cleft, molecules may then be ‘taken up’ by specially shaped receptor sites on the postsynaptic nerve cell (the dendrite) and so the chemical message is passed on. The relationship between the neurotransmitter molecule and the receptor site is like a lock and key, molecules will only fit certain receptor sites.. Spinal cord.
