opens a channel that selectively permeable to monovalent cations equally permeable. large inward sodium, smaller outward potassium, result is large inward current. current

movement. In Cl-,
have outward cl

moving in. inward
outside). way of thinking:
1. some current will leak out. current travel through
path of least resistance. there's less current available
to depolarize the membrane.
2. calculate the membrane potential (goldman). if left
membrane is permeable to both potassium and
sodium, membrane potential is halfway between Eca
and Ena which is way to depol...
