  1. Neurotransmitters

  2. Neurotransmitters

  3. Acetylcholine (ACh) • Enables muscle action, REM sleep, and memory • Undersupply, as ACh-producing neurons deteriorate, marks Alzheimer’s disease

  4. Dopamine • Reward and Motivation, Motor Control over Voluntary Movements • Excessive dopamine receptor activity is linked to schizophrenia; a lack of dopamine produces the tremors and lack of mobility of Parkinson’s disease

  5. Serotonin • Affects mood, hunger, temperature regulation, sleep, and arousal • Undersupply is linked to depression; Prozac and other anti-depressants raise serotonin levels

  6. Norepinephrine • Helps to control alertness, dreaming, waking from sleep, reactions to stress • Undersupply can depress mood

  7. GABA • Neural inhibitor with a tranquilizing effect. • Undersupply linked to seizures, tremors, and insomnia

  8. Glutamate • Involved in memory • Oversupply can overstimulate the brain, producing migraines or seizures

  9. Endorphins • Natural opiates that are released in response to pain and vigorous exercise

  10. Epinephrine • Adrenaline Burst of Energy (small amounts in brain)
