12.5 Graded Potentials

Graded potential

a shift in the electrical charge in a tiny area of a neuron

Hyperpolarizing graded potential

when the response makes the membrane more polarized (inside more negative)

Depolarizing graded potential

when the response makes the membrane less polarized (inside less negative)

Decremental conduction

mode of travel by which graded potentials die out as they spread along the membrane

Summation

accumulation; total result
