Chapter 37, Problem 11(choose chapter or problem)
An action potential is an all-or-none event. This on/off signaling is an evolutionary adaptation of animals that must sense and act in a complex environment. It is possible to imagine a nervous system in which the action potentials are graded, with the amplitude depending on the size of the stimulus. What evolutionary advantage might on/off signaling have over a graded (continuously variable) kind of signaling?
