Dr. Andrus studies reflexes and has demonstrated that a certain reflex doesn't occur if there is a single stimulus. He found that there needs to be _______ (several, rapidly produced stimuli) for the reflex to occur.
A) IPSPs
B) synaptic delay
C) temporal summation
D) spatial summation

Question

Quizplus · Accepted Answer

Temporal summation refers to the addition of multiple impulses arriving at a synapse in rapid succession, which can result in the generation of an action potential. In this case, Dr. Andrus has found that multiple stimuli need to be presented in rapid succession for a certain reflex to occur, indicating the phenomenon of temporal summation. None of the other options (IPSPs, synaptic delay, or spatial summation) are directly related to Dr. Andrus's findings about reflexes and the need for multiple rapid stimuli.
