  2. The set of neurons that transmit information between neurons (12)
  3. Abbreviation for the 6-8 msec period during which a neuron can produce a second neural response but only for much stronger stimuli (3)
  4. This equation allows calculation of the charge difference to balance off the concentration gradient for a permeating ion across a membrane (6)
  5. The white fatty wrapping that reduces current leakage across a nerve membrane (6)
  6. The white fatty wrapping that reduces current leakage across a nerve membrane (4)
  7. The glial cells in the periphery that provide a fatty insulation to some nerve axons (7, 5)
  8. One of the two factors used by channels to be selective as to what ion will pass through (4)
  9. The class of cells that make up 90% or so of the CNS (4)

  4. The parameter of neural signals that neurons vary to signal changes in stimulus intensity (9)
  5. Abbreviation for the period during which a neuron is completely unable to produce a neural response (3)
  6. The term for the trigger level for an action potential (9)
  7. The unmyelinated regions of a myelinated nerve where neural signals are regenerated (5)
