Synaptic transmission of graded membrane potential changes …

WebGraded potentials are small changes in membrane potential that are either excitatory (depolarize the membrane) or inhibitory (hyperpolarize the membrane). Many excitatory graded potentials have to happen at once to depolarize the cell body enough to trigger the action potential.
