alleryStart learning →Under the all-or-none principle, a stronger stimulus above threshold gives an action potential that is
ALarger in amplitude
BOf the same amplitude
CLonger in duration
DSlower to propagate
Answer & Solution
Correct answer: B. Of the same amplitude
Larger currents do not make larger spikes; an action potential either fires fully or not at all.
