Physioex 9.0 Exercise 3 Predict/Stop and Think Questions Activity 5

Experiment Results
Predict Question:
Predict Question: If you further decrease the interval between the stimuli, will the threshold for the second action potential
change?
Your answer : c. The threshold for the second action potential will be higher (requiring a larger depolarization).

Stop & Think Questions:
Threshold can be defined as the minimum voltage needed to generate an action potential. Is the threshold for the first action
potential the same as, or different from, the threshold for the second action potential with a 60 msec interval?
You correctly answered: a. The threshold for the first action potential is lower than the threshold for the second action
potential.
