  14. What is a neurotransmitter?- localized within the presynaptic neuron
    - released by presynaptic neuron when action potentials depolarize the terminal

          

  15. Cerebellum:Involved in maintenance of balance and posture, timing of motor movements, coordination of voluntary movements, and cognitive functions

          

  16. How can the action potential regenerate itself?Voltage-Gated Ion Channels

          

  17. NeuronsBasic signaling units that transmit info throughout the nervous system
    -To receive, assimilate, and finally transmit information

    -Neurons arranged in layers of tissue

          

  22. Information to Entropy....Information is inversely proportional to entropy

          

  23. Axon Collaterals- creates transmembrane passageways
    -selectively permeable

          

  24. Binary representation: Example.On/Off; one or the other (0 or 1)

    Example: ARE you confident?

          

  25. What is the role of the Cerebellum?- localized within the presynaptic neuron
    - released by presynaptic neuron when action potentials depolarize the terminal

          

  26. Sodium-Potassium Pumprepeatedly transports 3 Na+ ions OUT of the cell while drawing 2 K+ ions IN cell.

          

  27. Brain Stemlittle knobs attached by small necks to the surface of dendrites

          

  28. Resting PotentialA rapid depolarization and repolarization of a small region of the membrane caused by the opening and closing of ion channels.

          

  29. Gated Ion ChannelsChange their permeability for a particular ion
