Which experimental stimulus would most likely produce the greatest response in a postsynaptic neuronal membrane? A) A rapid stimulus that hyperpolarizes some parts of the membrane and depolarizes others B) A sudden stimulus that opens Ca²⁺ channels C) A single stimulus that increases neurotransmitter synthesis D) A steady stimulus that makes the resting membrane potential more negative E) A repeated stimulus that occurs at different sites on the postsynaptic cell

Question

Quizplus · Accepted Answer

A repeated stimulus occurring at different sites on the postsynaptic cell is most likely to produce the greatest response because it can lead to temporal and spatial summation, increasing the likelihood of reaching the threshold for an action potential.
