| isomorphic response | An isomorphic reaction seen in response to trauma in previously uninvolved sites of patients with skin diseases including psoriasis and lichen planus, typically with lesions in a linear pattern at sites of scratching or a scar. Synonym: isomorphic response. (05 Mar 2000) |
|---|---|
| oculomotor response | Widespread myogenic potential evoked by visual stimuli. (05 Mar 2000) |
| orienting response | An aspect of attending in which an organism's initial response to a change or to a novel stimulus is such that the organism becomes more sensitive to the stimulation; e.g., dilation of the pupil of the eye in response to dim light. Synonym: investigatory reflex, orienting response. (05 Mar 2000) |
| overall response rate | <pharmacology> Sum of complete and partial tumour responses seen in a study, divided by the number of evaluable patients. (05 Jan 1998) |
| target response | In conditioning, any behaviour or specific response chosen by the experimenter; its frequency is intended to increase or decrease by the judicious pairing with it of a reinforcer when it occurs. Synonym: target behaviour, target response. (05 Mar 2000) |
| th1 response | <immunology> An acquired immune response whose most prominent feature is high cytotoxic T lymphocyte activity relative to the amount of antibody production. The Th1 response is promoted by CD4+ Th1 T-helper cells. See: Th2 Response. (09 Oct 1997) |
| th2 response | <immunology> An acquired immune response whose most prominent feature is high antibody production relative to the amount of cytotoxic T lymphocyte activity The Th2 response is promoted by CD4+ Th2 T-helper cells. See: TO Response. (09 Oct 1997) |
| early-phase response | Prompt onset of symptoms following an antigenic stimulus. (05 Mar 2000) |
| triple response | <immunology> The vascular changes in the skin in response to mild mechanical injury, an outward spreading zone of reddening flare) followed rapidly by a weal (swelling) at the site of injury. Redness, heat and swelling, three of the cardinal signs of inflammation, are present. (18 Nov 1997) |
| evoked response | An alteration in the electrical activity of a region of the nervous system through which an incoming sensory stimulus is passing; may be somatosensory (SER), auditory (BAER), or visual (VER). See: evoked potential. (05 Mar 2000) |
| evoked response audiometry | A type of electrophysiologic audiometry in which electrical potentials of neural impulses from the cochlear nerve and various levels in the brain in response to acoustic stimulation are used to localise the site of a lesion causing a hearing loss. (05 Mar 2000) |
| unconditioned response | A response, such as salivation, which is a part of the animal or human repertoire. Compare: conditioned response. (05 Mar 2000) |
| flight or fight response | See: emergency theory. (05 Mar 2000) |
| late-phase response | Recurrence of symptoms after an appreciable interval following challenge with an antigen; preceded by an initial early-phase response. (05 Mar 2000) |
| lh response to gnrh | This test measures the level of luteinising hormone in the blood after an injection of gonadotrophin releasing hormone (GNRH), normally produced in the hypothalamus. This will test the ability of the pituitary gland to respond by measuring one of the pituitary glands byproducts, luteinising hormone. This test is used to differentiate hypogonadism (ovary or testes) into primary hypogonadism (problem is with the ovary or testes) or secondary hypogonadism (problem is with the pituitary gland or the hypothalamus).
