Skin conductance, also known as galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR) or skin conductance level (SCL), is a method of measuring the electrical conductance of the skin, which varies with its moisture level. This is of interest because the sweat glands are controlled by the sympathetic nervous system, so skin conductance is used as an indication of psychological or physiological arousal. There has been a long history of electrodermal activity research, most of it dealing with spontaneous fluctuations or reactions to stimuli.

Famous quotes containing the word skin:
“You flicker. I cannot touch you.
I put my hands among the flames. Nothing burns.
And it exhausts me to watch you
Flickering like that, wrinkly and clear red, like the skin of a mouth.”
—Sylvia Plath (1932–1963)
