The action action potential produced needs to reach the threshold for the AP to be propagated. If it doesn't reach the threshold, there is not enough Na+ to stimulate the positive feedback system which allows the action potential to be self-propagated. Instead, K+ channels will be opened, and it will enter repolarisation phase, and the AP wll not be conducted.
all stimuli great enough to bring the membrane to threshold will produce identical action potentials. :)
From Threshold to Threshold was created in 1955.
anti-threshold
An action potential needs to occur to trigger the neurons but the action potential depends on whether a stimulus is able to bring the membrane potential to a certain level termed the THRESHOLD. This threshold is about -55 mV for most neurons, but the stimulus needs to bring the membrane potential to this certain level or it will not be triggered. Relating to the ALL-OR-NONE PRINCIPLE, which if the threshold is not acquired then an action potential will not occur but once a stimulus is strong enough to depolarize (making the inside of the cell less negative going from -70 mV to -55 mV) it will trigger. The resting potential is -70 mV which the stimulus needs to bring it up to -55mV.
