Once the charge reaches +40 mv, the impulse is broadcast down the nerve fiber, and carried down the nerve through a series of action potentials. All of this requires that the threshold be met for the firing to occur in the first place. If it is, the electrical signal will be sent down the axon. Actions potentials either happen or they don’t, which is the principle of the all-or-none law. This mechanism ensures the neurons fire at full strength, with a consistent intensity that allows the signal to be carried down the fiber and transferred to the next cell without
