The level below which there is no response to a stimulus.<\/p>\n
Some value a stimulus must reach to produce a response.<\/p>\n
The point at which something starts, e.g. where something can be perceived by the body or where a drug starts to have an effect.<\/p>\n
The point at which a sensation is strong enough to be sensed by the sensory nerves.<\/p>\n
Minimal point at which a stimulus evokes a response.<\/p>\n
The point at which a stimulus begins to evoke a response, and therefore a measure of the sensitivity of a system under particular conditions. A thermoreceptor that responds to an increase in temperature of only two degrees is said to have a much lower threshold than one that will only respond to a change in temperature of ten degrees or more. In this example the threshold can be measured directly in terms of degrees.<\/p>\n
The degree of stimulation, or electrical depolarization, necessary to produce an action potential in a nerve-fibre. Stimulation below this level elicits no conducted impulse, and supramaximal stimulation will elicit the same response as a threshold stimulus.<\/p>\n
Point at which a psychological or physiological effect begins to be produced.<\/p>\n
The minimal level of stimulus that can create an impact on consciousness or trigger a response.<\/p>\n
The opening of a canal.<\/p>\n
