  1. Neurons?
    receive and send signals from sense organs and other neurons. About 100 billion (like computers)
  2. Three types of neurons?
    Sensory: respond to sensory like eyes, ears, nose, throat, and touch

    Motor: brain and spinal cord to muscles for movement

    Interneurons: link sensory and motor neurons. (*Most neurons)
  3. Brain Circuits?
    Big clumps of neurons
  4. Terminal Buttons
    release chemicals when neurons connect
  5. Cell body?
    Controls activities and integrates inputs
  6. Dendrites?
    Receive info from other Neurons.
  7. Action potential?
    shifting change that moves down the axon. Basis of neural communication.
  8. All of none law?
    If neuron is sufficiently stimulated it fires. Either the action occurs or it does not.
  9. Myelin?
    fatty substance that helps impulses travel down axon
  10. Synapse?
    Where communication between neurons occur
  11. Dopamine?
    affects motivation, rewards movements, and learning. Treat Parkinsons, ADHD, Depression, Schizo

    Drugs: Cocaine, Amphetamine
  12. Serotonin?
    Mood and sleep. Treats OCD, insomnia, depression

    Drugs: Prozac, tricyclia
  13. Agonist?
    mimics effects of neurotransmitters
  14. Antagonists?
    Blocks a particular receptor
  15. Peripheral Nervous System?
    Allows brain to affect organs of the body and receives info from them
  16. Autonomic Nervous System
    • Smooth muscle
    • Digestion / circulation

    • Sympathetic and Parasympathetic
    • (Emergencies)   (Slows things down)
  17. Sensory Somatic
    Carries info from skin and sensory organs to central nervous systems. Includes somatic motor system.
  18. Visible Brain
    Lobes and Landmarks
  19. Occipital Lobe
  20. Parietal Lobe
    Distance, movement, touch
  21. Frontal Lobe
    Makes us human different. Planning, specific memories, speech control, emotion

    Contains motor strip
  22. Temporal Lobe
    Sound, memory, and language
  23. Corpus Callosum
    Large bundle of axons that connects two halves of the brain together
  24. Cerebral Cortex
    pinkish gray outer layer of brain

    - Most mental processes
  25. Sulci
    Creases of the brain
  26. Gyri
    Areas of brain that bulge
  27. Limbic System
    emotion, motivation, fighting, fleeing, feeding, and sex.
  28. Hippocampus
    Storing new memories
  29. Amygdala
    fear and anger
  30. Hippo-campus
    store new information elsewhere in the brain
  31. Functional Magnetic Resonance Imaging
    most common type of neuroimaging
