Refractory Period

(neurology) the time after a neuron fires or a muscle fiber contracts during which a stimulus will not evoke a response.The period of time where an axon of a neurone is inable to transmit further nerve signals immediately after doing so, occurring for about 3 milliseconds. It is possible for another signal to be passed through providing the signal is very strong and superc.
