Document Summary

A new viral disease has been found that destroys the myeline sheath, the likely result is (a) a slower neural connection. Inte neurons relay stations *how do neurons work ref to video. Extracellular uid the cell membrane is semipermeable. **important: the action potential resting membrane potentail -70mv. If there is a stimulus there will be change in charge becoming more positive (when stimulated the cell membrane allows for sodium to enter, depolarization na^+ in ow) If below -70 then it is hyper-polarized during the depolarization, it is called refractory period. From the +40 to the -70, this is the absolute refractory period where nothing can happen, no other stimulus can be red again. The second part is the relative refractory, from the bottom of the refractory back to threshold, it is below resting potential so something can happen but it needs to be very strong. If the neuron does not go past the threshold nothing happens.
