// E4.1 State that some presynaptic neurons excite postsynaptic transmission and others inhibit postsynaptic transmission. //

// E4.2 Explain how decision-making in the CNS can result from the interaction between the activities of excitatory and inhibitory presynaptic neurons at synapses. //

// E4.3 Explain how psychoactive drugs affect the brain and personality by either increasing or decreasing postsynaptic transmission. Include ways in which synaptic transmission can be increased or decreased. //

Include ways in which synaptic transmission can be increased or decreased. Details of the organization and functioning of the entire brain, and theories of personality or explanations for personality, are not required.

// E.4.4 List three examples of excitatory (nicotine, cocaine and amphetamines) and three examples of inhibitory (benzodiazepines, alcohol and tetrahydrocannabinal – THC) psychoactive drugs. //

Use the following examples. • Excitatory drugs: nicotine, cocaine and amphetamines • Inhibitory drugs: benzodiazepines, alcohol and tetrahydrocannabinol (THC).

// E4.5 Explain the effects of THC and cocaine in terms of their action at synapses in the brain. Include the effects of these drugs on both mood and behaviour. //

Include the effects of these drugs on both mood and behaviour.

// E4.6 Discuss the causes of addiction, including genetic predisposition, social factors and dopamine secretion. //
