A neuron responds to adequate stimulation with _______ a type of self-propagating signal.
Electrical impulse: change in membrane potential that generates a signal. An adequate stimulus acts on a neuron and can trigger gated channels to open, allowing ions to diffuse rapidly into the cell, producing local depolarization. When the threshold potential is reached, the gated channels open and more Na+ ions enter the cell, causing further depolarization. This state is an all-or-none response and is an example of a feedback mechanism. The above channels only stay open for about 1ms and then automatically close. After the action potential peaks, the membrane begins to move back toward the resting membrane potential due to the activation of gated channels, allowing outward diffusion of ions. This process is known as repolarization.

Graded potentials are often all-or-none, always cause repolarization. They may be either a depolarization or a hyperpolarization; they produce an effect that spreads actively across the membrane surface without diminishing and increases with distance from the point of stimulation.
