A neuron was stimulated with 0.075 volts, and no action potential occurred. Later, it was stimulated with 0.15 volts, and it fired an action potential. What conclusions can you draw from this?
Acetylcholinesterase levels were too high.
The action potential threshold must be between 0.075 V and 0.15 V.
Both of these stimuli are too weak to produce an action potential.
All of the above
B. The action potential threshold must be between .075 V and .15 V.
