KEY NEUROTRANSMITTERS & THEIR FUNCTIONS
AMINO ACIDS:
GLUTAMATE: most prevalent EXCITATORY neurotransmitter
oLearning
oMemory
oProvoking seizures
GABA: most prevalent INHIBITORY neurotransmitter
oInhibition of seizures
oAnxiety (anti-anxiety meds target GABA)
oOpium GABA activity down dopamine release up
ACETYLCHOLINE: EXCITATORY, CNS & peripheral, complex mental
processes
oLearning
oDreaming
oMEMORY
**Alzheimers patients have low Acetylcholine levels**
EPINEPHRINE: EXCITATORY functions in peripheral system
oArousal & alertness
oHeightened attention
NOREPINEPHRINE: the CNSs version of epinephrine
Depression: not enough
Anxiety: too much
ADHD: not enough
SEROTONIN: monoamine neurotransmitter
oMood (depression, anxiety, motivation problems etc)
depression treatments often target serotonin
ex: Prozac inhibits serotonin reuptake
oDreaming
oImpulse Control
DOPAMINE: reward! And motor control planning
