acetylcholine
learning
glutamate
memory (most prevalent, excitatory)
endorphins
euphoria
what are the properties of neurotransmitters?
synthesised in presynaptic neuron, stored in vesicles
released when an action potential arrives (stimulus)
postsynaptic neuron contains receptors
how do drugs affect the neurotransmitters?
drugs elicit the same response as neurotransmitters causing overstimulation, overflow in synapses, and blockage of receptors
steps of neurotransmission
action potential arises
calcium floods in
neurotransmitters release
excitatory vs. inhibitory
excitatory = stimulating
inhibitory = calming
LSD
hallucinogen
binds to serotonin receptors to inhibit or excite them
cocaine
stimulant
blocks dopamine transporters, causing overstimulation
alcohol
depressant
reacts with GABA to make them more inhibitory, binds to glutamate receptors to prevent them from exciting the cell
meth
stimulant
mimics dopamine, causing an overflow in the synapse and overstimulation by continuous binding to receptors
marijuana
depressant
blocks the release of inhibitory neurotransmitters, resulting in extra release of dopamine into the synapse
ecstasy
stimulant
mimics serotonin, causing serotonin to continuously bind to receptors and overstimulation
heroin
depressant
blocks the release of inhibitory neurotransmitters, resulting in extra release of dopamine into the synapse
