Elena is given a drug that moves the resting potential of her neurons to ?90 mv. What effect will this likely have on Elena?
A) It will take less stimulation to get her neurons to fire action potentials.
B) It will take more stimulation to get her neurons to fire action potentials.
C) It will be impossible to get her neurons to fire action potentials.
D) Her neurons will begin to fire action potentials at random.

Question

Quizplus · Accepted Answer

The resting potential of -90 mv is farther from the threshold potential required to trigger an action potential, which is typically around -55 mv. Therefore, it would take more stimulation to reach that threshold and trigger an action potential.
