   Rheobase
   In neuroscience, `rheobase` is the minimal electric current of infinite duration (practically, a few hundred milliseconds) that results in an action potential or the contraction of a muscle. In the case of a nerve or single muscle cell, rheobase is half the current that needs to be applied for the duration of chronaxie to result in an action potential or muscle twitch. This can be understood better by looking at a strength duration relationship....

   rheobase
   (re´o-bās) the minimal electric current of infinite duration necessary to produce a twitch in a muscle. In a strength-duration curve for muscle stimulation, it is the voltage at which there is no further decrease in threshold when the pulse width or duration is increased.
