Action potential
RELATIVE -
- Another action potential can be produced, but only if the stimulus is greater than the threshold stimulus
- corresponds to the period when the potassium channels are open (several milliseconds)
- the nerve cell membrane becomes progressively more 'sensitive' (easier to stimulate) as the relative refractory period proceeds. So, it takes a very strong stimulus to cause an action potential at the beginning of the relative refractory period, but only a slightly above threshold stimulus to cause an action potential near the end of the relative refractory period.
