What can drugs tell us about how neurons operate?
Outline how drugs target receptors on surface of neurons and serve as agonists or antagonists to natural neurochemicals.
Include details of how some block reuptake of a neural chemical while other mimic actions of endogenous equivalent of drug (e.g. cannabis)
Explain how drugs alter activity of neurons and effect on cognition, mood and behaviour giving examples and study
Explain how helps understand natural role of neuron transmitters in governing these functions
