| stimulus word | The word used in association tests to evoke a response. (05 Mar 2000) |
|---|---|
| neutral stimulus | When paired with the unconditioned stimulus in simultaneous presentation to an organism, capable of eliciting a given response. (05 Mar 2000) |
| subliminal stimulus | A stimulus too weak to evoke a response. Synonym: subliminal stimulus, subthreshold stimulus. (05 Mar 2000) |
| subthreshold stimulus | A stimulus too weak to evoke a response. Synonym: subliminal stimulus, subthreshold stimulus. (05 Mar 2000) |
| supramaximal stimulus | A stimulus having strength significantly above that required to activate all of the nerve or muscle fibres in contact with the electrode; used when response of all the fibres is desired. (05 Mar 2000) |
| discriminant stimulus | A stimulus which can be differentiated from all other stimulus in the environment because it has been, and continues to serve as, an indicator of a potential reinforcer. (05 Mar 2000) |
| inadequate stimulus | A stimulus too weak to evoke a response. Synonym: subliminal stimulus, subthreshold stimulus. (05 Mar 2000) |
| threshold stimulus | A stimulus of threshold strength, i.e., one just strong enough to excite. See: adequate stimulus. Synonym: liminal stimulus. (05 Mar 2000) |
| train-of-four stimulus | A method for measuring magnitude and type of neuromuscular blockade, based upon the ratio of the amplitude of the fourth evoked mechanical response to the first one, when four supramaximal 2-Hz electrical currents are applied for 2 seconds to a peripheral motor nerve. (05 Mar 2000) |
| unconditioned stimulus | A stimulus that elicits an unconditioned response; e.g., food is an unconditioned stimulus for salivation, which in turn is an unconditioned response in a hungry animal. See: classical conditioning. (05 Mar 2000) |
| liminal stimulus | A stimulus of threshold strength, i.e., one just strong enough to excite. See: adequate stimulus. Synonym: liminal stimulus. (05 Mar 2000) |
| calorimetry, indirect | Calculation of the energy expenditure in the form of heat production of the whole body or individual organs based on respiratory gas exchange. (12 Dec 1998) |
| indirect | 1. Not immediate or straight. 2. Acting through an intermediary agent. Origin: L. Indirectus (18 Nov 1997) |
| indirect agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| indirect assay | For antibody; an application of the ELISA method in which serum being tested for antibody is added to wells coated with known antigen; presence of antibody bound to the antigen coat can be determined by addition of immunoglobulin-specific antibody to which is linked the enzyme of the indicator system, followed by addition of substrate to the washed aggregate.
