Resting membrane potential
Voltage difference between inside and outside of cell; inside is negative (~ −65 mV).

Contributors to resting membrane potential
Selective membrane permeability (especially K⁺ channels), diffusion, electrostatic forces, sodium-potassium pump (3
Na⁺ out, 2 K⁺ in).
Potassium equilibrium at rest
At resting potential, diffusion force outward equals electrostatic force inward for K⁺.
Polarized
Neuron has a negative resting membrane potential.
Depolarization
Membrane becomes more positive (less negative).
Hyperpolarization
Membrane becomes more negative.

Voltage
Measure of stored or potential energy (potential difference).
Current
Rate of flow of energy.
Equilibrium
Balance of forces; does not mean equal amounts.
Graded potential
Passive spread of electrical current; decays over time and distance; not regenerated; occurs in dendrites and soma;
also called electrotonic conduction.
EPSP (Excitatory postsynaptic potential)
Synaptic potential that increases chance of future action potential; typically due to opening of ligand-gated Na⁺
channels.
