1. Most of the cells in your brain are neurons. 2. The Nernst Equation is: E = 60 mV log10 ([Xextracellular/Xintracellular]). Given this, the equilibrium potential for a given ion would be increased with an increase in its intracellular concentration. 3. The Nernst Equation is: E = 60 mV log10 ([Xextracellular/Xintracellular]). Given this, the equilibrium potential for a given ion would be increased with an increase in its extracellular concentration. 4. Action potentials are typically also graded potentials.
