all-or-none
all-or-none (ôl'ər-nŭnʹ) adj.
Characterized by either a complete response or by a total lack of response or effect, as in neurological action above a threshold: “Nerve impulses follow the All or None Law—that is, a nerve impulse generated by a weak stimulus is just as strong as one generated by a strong stimulus” (Fundamentals of Biology).
