In physiology, the all-or-none law (sometimes the all-or-none principle or all-or-nothing law) is the principle that if a single nerve fibre is stimulated, it will always give a maximal response and produce an electrical impulse of a single amplitude. If the intensity or duration of the stimulus is increased, the height of the impulse will remain the same. The nerve fibre either gives a maximal response or none at all.

The all-or-nothing law is an important principle that describes how nerve cells either fire at full strength or do not. Because of this, important information does not lose strength as it is carried to the brain, ensuring that people are able to respond to environmental stimuli. See more If a stimulus is strong enough, an action potential occurs and a neuron sends information down an axon away from the cell body and toward the synapse. Changes in cell … See more In its normal resting state, the inside of a neuron is around -70 millivolts. When activated by the stimulus, the membrane depolarizes, causing … See more Some examples of the all-or-none response can be seen in different sensory and perceptual situations. For example: 1. Touching a hot pan 2. Smelling a delicious scent 3. Feeling the coldness of a glass of water 4. Detecting … See more The body still needs to determine the strength or intensity of a stimulus.
