Latency /(?)/

La·ten·cy

Latency

n.
  1. The state or quality of being latent.
    To simplify the discussion, I shall distinguish three degrees of this latency.
  2. The time between a stimulus the appearance of the response; the time between any causal action and the first appearance of the effect. Called also latent period.
  3. The time between exposure to a carcinogen or other disease-causing agent and the appearance of the consequent disease. (Med.)
