acute phase response  a group of physiological processes occurring soon after the onset of infection, trauma, inflammatory processes, and some malignant conditions; it includes increase in acute phase proteins in serum, fever, increased vascular permeability, and metabolic and pathologic changes.

anamnestic response  secondary immune r.

autoimmune response  the immune response against an autoantigen.

conditioned response  a response evoked by a conditioned stimulus; a response to a stimulus that was incapable of evoking it before conditioning.

galvanic skin response  the alteration in the electrical resistance of the skin associated with sympathetic nerve discharge.

immune response  any response of the immune system to an antigenic stimulus, including antibody production, cell-mediated immunity, and immunological tolerance.

primary immune response  the immune response occurring on the first exposure to an antigen, with specific antibodies appearing in the blood after a multiple day latent period.

relaxation response  a group of physiologic changes that cause decreased activity of the sympathetic nervous system and consequent relaxation after stimulation of certain regions of the hypothalamus. They may be self-induced through techniques such as meditation and biofeedback.

secondary immune response  the immune response occurring on second and subsequent exposures to an antigen, with a stronger response to a lesser amount of antigen, and a shorter lag time compared to the primary immune response.

triple response (of Lewis)  a triphasic skin reaction to being stroked with a blunt instrument: first a red line develops at the site due to histamine release, then a flare develops around the red line, and lastly a wheal is formed as a result of local edema.

unconditioned response  an unlearned response, i.e., one that occurs naturally to an unconditioned stimulus.

gal·van·ic skin response (gl-vnk)

n. Abbr. GSR

A measure of electrical resistance as a reflection of changes in emotional arousal, taken by attaching electrodes to any part of the skin and recording changes in moment-to-moment perspiration and related activity of the autonomic nervous system.

galvanic skin response (GSR)

Etymology: Luigi Galvani; AS, scinn + L, respondere, to reply

a reaction to certain stimuli as indicated by a change in the electrical resistance of the skin. The effect is related to subconscious activity of the sweat glands and may result from pleasant as well as unpleasant stimuli. The GSR is used in some polygraph examinations.

galvanic skin response,

n change in electrical conductivity of the skin usually brought on by changes in emotion—for example, fear. Also known as
electrodermal response. See also biofeedback.

response

any action or change of condition evoked by a stimulus.

autoimmune response

the immune response in which antibodies or immune lymphoid cells are produced against the body's own tissues.

conditioned response

see also conditioned response, conditioning.

dazzle response

shining a bright light in the eye causes a blink. Called also dazzle reflex.

galvanic skin response

the alteration in the electrical resistance of the skin associated with sympathetic nerve discharge.

immune response

specifically altered reactivity of the animal body after exposure to antigen, manifested as antibody-production, cell-mediated immunity, development of hypersensitivity, or as immunological tolerance. Called also immune reaction. See also immune response.

maze response

a test of vision for animals.

placing response

see placing reflex.

response rate

in surveys, the number of completed survey instruments (questionnaires, interview records) divided by the total number of persons approached.

response trial

a field trial conducted to test a hypothesis, often about the cause of a disease but can encompass therapeutics or control of a disease. The hypothesis is tested by observing the response to an alteration in the system, e.g. in feeding or in management.

triple response (of Lewis)

a physiological reaction of the skin to stroking with a blunt instrument: first a red line develops at the site of stroking, owing to the release of histamine or a histamine-like substance, then a flare develops around the red line, and lastly a wheal is formed as a result of local edema.

unconditioned response

an unlearned response, i.e. one that occurs naturally. See also conditioning.
