Rheobase

Jump to navigation Jump to search

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. [1] This can be understood better by looking at a strength duration relationship. [2]


This is in short the : "Minimal Electrical current that results in an action potential"
