In the mathematical description of the functioning of the nervous system, the chronaxie (or chronaxy) is the minimum time over which an electric current double the strength of the rheobase needs to be applied, in order to stimulate a muscle fiber or nerve cell. The terms "chronaxie" and "rheobase" were coined in 1909 by the French physiologist Louis Lapicque. [1]
