Question

7.) In this activity the word frequency refers to

A.) The number of millivolts needed to reach threshold.

B.) The potential in millivolts when the neuron is at rest (resting membrane potential).

C.) The number of action potentials per second.

D.) The potential in millivolts at the peak of the action potential.

8.) Suppose you are studying a Pacinian corpuscle. You record the action potentials in

the axon leaving the corpuscle. The experiment is to apply pressure to the

corpuscle three times: low pressure, medium pressure and high pressure. The

information about the strength of the pressure is encoded in the

Action potential frequency

Threshold potential

Action potential amplitude

Resting membrane potential

There is no information about strength of pressure, because all action potentials have the same shape.

7.D. The potential in millivolts at the peak of action potential.

8.A.Action potential frequency
