In a negative feedback loop, the effector moves the system in the direction as the stimulus.
Which of the following statements about the intensity of a nerve response is true?
Select one:
a. A stimulus reaching the threshold level may or may not propagate a nerve impulse.
b. A small voltage shift and a large voltage shift will yield the same nerve impulse as long as the stimulus reaches the threshold level.
c. All stimuli, regardless of the strength, will always generate a nerve impulse.
d. A stimulus resulting in a greater voltage shift will result in a stronger nerve impulse and increased sense of perception in the brain.
