Yоu hаve а neurоn thаt has 122 mM Na+ оutside and 8 mM Na+ inside. It also has 140 mM K+ inside and 3 mM K+ outside. What is the EK (3 points)? What is the ENa (3 points)? Assuming that you have a 3-fold higher permeability to K+, what is the Vm in this neuron (3 points)? If you suddenly double the Na+ permeability, what is the new Vm (4 points)? Explain if this is enough of a change to start an action potential if this Vm occurs at the axon hillock (3 points).
