Graded potentials are changes in membrane potential that are confined to a relatively small region of the plasma membrane and die out within 1 to 2 mm of their. Section 212 the action potential and conduction of electric impulses changes in the voltage across the membrane that lead to propagation of action potentials. Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron. I was under the impression the only signals neurons send using changes in membrane potential are action potentials but my biology professor showed us diagrams of. Epsps graded potentials that make the membrane potential less negative or more positive, thus making the postsynaptic cell more likely to have an action potential.
The formation of an action potential can be divided into five steps (1) a stimulus from a sensory cell or another neuron causes the target cell to depolarize.
