Title: How does the threshold voltage change during the relative refractory period?
Post by: pilor on Nov 29, 2011
  Need help with a couple questions please from PhysioEx 9.0 exercise 3.
How does the threshold voltage change during the relative refractory period?

When the stimulus intensity is increased, what changes: the number of synaptic vesicles released or the amount of neurotransmitter per vesicle?

Thanks you are helping somebodies mom out :)

The number of synaptic vesicles released increases when the stimulus intensity increases.

Good luck.
