Presentation Transcript

  1. Neurotransmitters Researchers have identified over 75 chemical substances that are manufactured in the brain, spinal cord, glands and other parts of the body that may act as neurotransmitters.

  2. Useful vocabulary: Excitatory effects & Inhibitory effects Excitatory neurotransmitters trigger a nerve impulses in the receiving cell, while inhibitory neurotransmitters act to prevent further transmission of an impulse.

  3. Neurotransmitters AcetyicholineAch(ah-SEET-ul-KOH-leen)

  4. Neurotransmitters AcetyicholineAchExerts excitatory and inhibitory effects. Excitatory effects of voluntary muscles, causing them to contract so that you can move, but inhibitory effects on the muscle fibers in the heart.

  5. Neurotransmitters Example: When you run to class because there is a hall sweep acetyicholine helps your leg muscles contract quickly, while at the same time preventing your heart muscles from pumping so rapidly you pass out.

  6. Neurotransmitters AcetyicholineAlso plays a role in REM sleepand helping to understand and store new information. Critical for normal attention, arousal and memory. Acetyicholine is helping you right now!

  7. Neurotransmitters DopamineDA(DOE-pah-meen)

  8. Neurotransmitters DopamineProduces both excitatory and inhibitory effects. *Pleasure & Mood*Learning/Attention*Movement*Alertness

  9. Neurotransmitters Norepinephrine(nor-EP-ih-NEF-rin)NE

  10. Neurotransmitters Norepinephrine(nor-EP-ih-NEF-rin)NEAffects*Mood *Eating (Stimulates the intake of carbohydrates) *Alertness*Wakefulness*Learning

  11. Neurotransmitters Epinephrine(EP-ih-NEF-rin)EPI (adrenaline),

  12. Neurotransmitters Epinephrine(EP-ih-NEF-rin)EPI(Adrenaline)Compliments norepinephrine by affecting the metabolism of glucose and causing the nutrients stored in muscles to be released during strenuous exercise.

  13. Neurotransmitters Serotonin5HT(ser-oh-TOE-nin)

  14. Neurotransmitters Serotonin 5HT(ser-oh-TOE-nin)Regulates*Sleep*Mood*Impulsivity*Aggression*Appetite

  15. Neurotransmitters Glutamate(GLOO-tah-mate)

  16. Neurotransmitters Glutamate(GLOO-tah-mate)The primary excitatory neurotransmitter in the brain. It is released by about 40% of the neurons and is active in areas of the brain involved in learning, thought, and emotions.

  17. Neurotransmitters GABA(Short for “gamma-aminobutyric acid”)*Controls anxiety*Sleep*Movement

  18. Neurotransmitters GABA(Short for “gamma-aminobutyric acid”)The main inhibitory neurotransmitter in the brain. Controls anxiety in humans. Tranquilizers, barbiturates, and alcohol appear to have a calming effect because they bind with and stimulate one type of GABA receptor, thereby increasing GABA’s anxiety controlling effect.

  19. Neurotransmitters Endorphins(en-DOR-fins)

  20. Neurotransmitters Endorphins(en-DOR-fins)Chemicals produced naturally in the brain that reduce pain and the stress of vigorous exercise and positively affect mood.

  21. Neurotransmitters Endorphins(en-DOR-fins)General feelings of well-being and pleasure. (Runner’s high.) Opiate drugs such as heroin and morphine mimic the endorphins and bind to their receptor sites.
