"Depolarization," "absolute refractory period," and "threshold of excitation" are terms that apply most directly to ________.
A) brain wave patterns (EEGs)
B) neural synapses
C) computerized axial tomography
D) action potentials

Question

Quizplus · Accepted Answer

"Depolarization," "absolute refractory period," and "threshold of excitation" all refer to the generation and transmission of electrical impulses (action potentials) in neurons, making D the most appropriate option. Brain wave patterns (EEGs) are measured on the scalp and reflect the overall activity of large groups of neurons, while neural synapses refer to the small gaps between neurons where neurotransmitters are released. Computerized axial tomography (CT) is a type of brain imaging that uses X-rays to visualize brain structures.
