    • IPSP: graded hyperpolarization (this brings the cell past it's resting potential, thus requiring a bigger than normal stimulus to get it to threshhold, that's why it's called inhibitory. To do this, what ion has to move and it what direction?

    K+, out.)
  139. What neurotransmitter is associated with pain signals?
    Bradykinin.
