1. ELECTRO-PHYSIOLOGY & ACTION POTENTIAL

Ions, because they are charged, are influenced not only by their concentration gradient but also by electrical potential differences.

K+ -90 mVNa+ +60 mVCl- -70 mV

Equilibrium Potentials for Various IonsIf the concentration gradient for a given ion is known, the equilibrium potential for that ion can be calculated (using the Nernst Equation). Shown below are the equilibrium potentials calculated for K+, Na+ and Cl- using the ionic concentrations for a typical neuron.
