Presentation transcript:

Acetylcholine Muscle action Learning/Memory Decreased levels associated with Alzheimer disease

Dopamine Movement Learning, attention Emotion Excess associated with schizophrenia Decreased levels associated with Parkinson Disease

Serotonin Mood, hunger, sleep, arousal Decreased levels associated with depression

Norepinephrine Helps control alertness/arousal Decreased levels associated with depression

GABA “gamma-aminobutyric acid” Major inhibitory neurotransmitter Decreased levels associated with seizures, tremors, and insomnia

Glutamate Major excitatory neurotransmitter Involved in memory Excess associated with overstimulation, seizures, and migraine headaches

Endorphins Released in response to pain and exercise Basis for ‘runner’s high’ Prescription narcotics are potent agonists
