| stimulus generalization | In Pavlovian conditioning, the eliciting of a conditioned response by stimuli never before experienced but which are similar to a particular conditioned stimulus. See: conditioning, classical conditioning. (05 Mar 2000) |
|---|---|
| stimulus secretion coupling | A term used to describe the events that link receipt of a stimulus with the release of materials from membrane bounded vesicles (the analogy is with excitation contraction coupling in the control of muscle contraction). A classical example is the link between membrane depolarisation at the presynaptic terminal and the release of neurotransmitter into the synaptic cleft. (18 Nov 1997) |
| stimulus sensitive myoclonus | Myoclonus induced by a variety of stimuli, e.g., talking, calculation, loud noises, tapping, etc. (05 Mar 2000) |
| stimulus substitution | <psychology> Learning that takes place when a conditioned stimulus is paired with an unconditioned stimulus. (12 Dec 1998) |
| stimulus threshold | The lowest limit of any perception whatever. Compare: differential threshold. Synonym: stimulus threshold. (05 Mar 2000) |
| 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) |
