Chemicals

Dopamine

________- Involved in movement, attention, learning, pleasure and emotion, Excess- receptor activity linked to schizophrenia, Loss- tremors and decreased mobility of Parkinson's disease, Found in CNS and PNS.

Norepinephrine

________- Helps control alertness and arousal, Oversupply- fight or flight response, Undersupply- can depress mood, Found in CNS and ANS.

Anandamide

________- Involved in working memory, Possibly involved in eating and sleep patterns, motivation, pleasure and pain relief, Found in CNS.

Serotonin

________- Affects mood; hunger (and satiety), sleep and arousal, Undersupply linked to depression.

Endorphins

________- Natural, opiate- like neurotransmitters, Linked to pain control and to pleasure, Released in response to pain.

Glutamate

________- Major excitatory neurotransmitter, Involved in memory, Oversupply- associated with epileptic seizures and migraine headaches, Found in CNS and PNS.

GABA

________- Main inhibitory neurotransmitter, Undersupply- linked to seizures, tremors, and insomnia, Found in CNS.

Agonosists

________- Fits receptor well and acts like the NT, ex: nicotine.

Acetylcholine

________- Enables muscle action, learning and memory, Alzheimer's Disease, Found in CNS and PNS.

Antagonists

________- Fits receptor poorly, occupying the site without activating the receptor (blocks the NT)
