Galvanic Skin Response
galvanic skin response[gal′van·ik ′skin ri‚späns] (physiology) The electrical reactions of the skin to any stimulus as detected by a sensitive galvanometer; most often used experimentally to measure the resistance of the skin to the passage of a weak electric current. Also known as electrodermal response. Galvanic Skin Response psychogalvanic reflex, a change in potential difference or electric resistance between two points on the skin in response to various stimuli or emotional excitement; first described by the Russian physiologist I. R. Tarkhanov in 1889. Galvanic skin response is usually recorded by measuring the indexes between the palmar and dorsal surfaces of the hand or between the palmar surfaces of both hands. The galvanic skin response is a negative shift of biopotential or a decrease in electrocutaneous resistance caused by the activity of the sweat glands just before perspiration. This activity is induced by nervous impulses proceeding from the central nervous system through the sympathetic fibers. The central structures responsible for the galvanic skin response are found in the reticular formation of the mesencephalon and hypothalamus and are activated by the higher sections of the brain (chiefly the limbic system—the most important part of the brain’s emotional apparatus). The galvanic skin response is a component of the orientation reaction, that is, the response to unexpected change characterizing the processes leading to any kind of new action. L. P.

response [re-spons´] any action or change of condition evoked by a stimulus.acute phase response a group of physiologic processes occurring soon after the onset of infection, trauma, inflammatory processes, and some malignant conditions. The most prominent change is a dramatic increase of acute phase proteins in the serum, especially C-reactive protein. Also seen are fever, increased vascular permeability, and a variety of metabolic and pathologic changes.anamnestic response the rapid reappearance of antibody in the blood following introduction of an antigen to which the subject had previously developed a primary immune response.auditory brainstem response ABR; a special hearing test that tracks the nerve signals arising in the inner ear as they travel along the auditory nerve to the brain region responsible for hearing. A small speaker placed near the ear makes a clicking sound, and special electrodes record the nerve signal as it travels. The test can determine where along the nerve there is a lesion responsible for sensorineural hearing loss. It is often used for individuals with such loss in just one ear; this is often caused by a benign tumor along the auditory nerve, but if the ABR reading is normal in a given region, the chances of there being a tumor there are small. This test can also be used on infants since it requires no conscious response from the person being tested.autoimmune response the immune response in which antibodies or immune lymphoid cells are produced against the body's own tissues. See also autoimmune disease.conditioned response see conditioned response.dysfunctional ventilatory weaning response a nursing diagnosis adopted by the North American Nursing Diagnosis Association, defined as inability of a patient to adjust to lowered levels of mechanical ventilator support, which interrupts and prolongs the process of weaning. See also weaning" >mechanical ventilatory weaning.galvanic skin response the alteration in the electrical resistance of the skin associated with sympathetic nerve discharge.immune response see immune response.inflammatory response the various changes that tissue undergoes when it becomes inflamed; see inflammation.post-trauma response former name for the nursing diagnosis post-trauma syndrome.reticulocyte response increase in the formation of reticulocytes in response to a bone marrow stimulus.triple response (of Lewis) a physiologic 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, in contrast to a conditioned response.gal·van·ic skin re·sponse (GSR), a measure of changes in emotional arousal recorded by attaching electrodes to any part of the skin and recording changes in moment-to-moment perspiration and related autonomic nervous system activity.

Galvanic Skin Response
Galvanic Skin ResponseA physical response in the skin due to some stimulus. For example, turning red when one is nervous is a galvanic skin response. Some marketers measure galvanic skin responses on test subjects of advertisements. Proponents believe this is an objective way to determine a test subject's response to an advertisement, though critics contend that this practice does not sufficiently account for outside stimuli that may affect measurements.AcronymsSeeglutathione reductasegalvanic skin response
