Stimulus
Definition:
(v. t.) A goad; hence, something that rouses the mind or spirits; an incentive; as, the hope of gain is a powerful stimulus to labor and action.
(v. t.) That which excites or produces a temporary increase of vital action, either in the whole organism or in any of its parts; especially (Physiol.), any substance or agent capable of evoking the activity of a nerve or irritable muscle, or capable of producing an impression upon a sensory organ or more particularly upon its specific end organ.
Example Sentences:
(1) In the absence of atrial dilatation there was minimal stimulus for ANF secretion.

(4) Since intracellular Ca2+ seems to play a role in stimulus-secretion coupling and ion movements, several aspects of Ca2+ homeostasis have been investigated in CF.
(5) Three coyotes were operantly conditioned to depress one of two foot treadles, left or right, depending on the condition of the stimulus light.
(6) Clinical measurements of the loudness discomfort level (LDL) are generally performed while the subject listens to a particular stimulus presented from an audiometer through headphones (AUD-HP).
(7) NE differentially affected responses to stimulus movement in the preferred and non-preferred direction in one-third of these neurons, such that directional selectivity was increased.
(8) II, the visual and auditory stimuli were exposed conversely over the habituation- (either stimulus) and the test-periods (both stimuli).
(9) The marine vibrio alone is a powerful stimulus to mucus secretion but lethal for the host.
(10) Taken together with our previous studies showing that MDMA substitutes for the phenylisopropylamine stimulant (+)amphetamine, but that neither MDE nor N-OH MDA substitute for (+)amphetamine or for the phenylisopropylamine hallucinogen 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane (DOM), the present results [i.e., MDMA-stimulus generalization to MDE, N-OH MDA, but not to (+)amphetamine] suggest that 1) MDMA produces effects other than those that may be considered amphetamine-like, and 2) MDE and N-OH MDA are MDMA-like agents with even less of an amphetamine-like component of action than MDMA itself.
(11) Changes in pain tolerance after administration of differently labelled placebos were studied by measuring the reaction time after a cold stimulus.
