Galvanic skin response (or GSR), also known as electrodermal response (EDR) or psychogalvanic reflex (PGR), is a method of measuring the electrical resistance of the skin and interpreting it as an image of activity in certain parts of the body. The mapping of skin areas to internal organs is usually based on acupuncture point. Electrical resistance is a measure of the degree to which an electrical component opposes the passage of current. ...

Acupuncture points (also called acupoints or tsubo) are specific anatomical locations on the body that are believed to be therapeutically useful for acupuncture, acupressure, sonopuncture, or laser treatment. ...
Practice
GSR is conducted by attaching two leads to the skin, and acquiring a base measure. Then, as the activity being studied is performed, recordings are made from the leads. There are two ways to perform a GSR - in active GSR, current is passed through the body, with the resistance measured. In passive GSR, current generated by the body itself is measured. In electricity, current is the rate of flow of charges, usually through a metal wire or some other electrical conductor. ...
History GSR originated in the early 1900s. It was used for a variety of types of research in the 1960s through the late 1970s, with a decline in use as more sophisticated techniques (such as EEG and MRI) replaced it in many areas of psychological research. GSR still sees limited use today, as it is possible to use with low-cost hardware (galvanometer). // Events and Trends Technology Lawrence Hargrave makes the first stable wing design for a heavier-than-air aircraft Orville and Wilbur Wright make the first documented flight in a powered heavier-than-air aircraft Mass production of automobile Wide popularity of home phonograph Panama Canal is being built by the...

Uses Because the GSR is relatively simple and well documented it can be used to detect subconscious semantic knowledge. For example suppose that two subjects are suffering from prosopagnosia, however one of these subjects gets a GSR while the other does not; from this we could infer that the two subjects suffered from different (although similar) neural disfunction. Prosopagnosia (sometimes known as face blindness) is a rare disorder of face perception where the ability to recognize faces is impaired, although the ability to recognize objects may be relatively intact. ...
Non-research uses GSR has seen, outside of the research community, usage as a lie detector, under the theory that telling of lies increases perspiration, changing the conductance of skin. Its accuracy, because of its limited scope, is believed to be even less significant than that of a regular polygraph. GSR is also used by Scientologists, who call their devices E-meters, in their spiritual counseling. A polygraph or lie detector is a device which measures and records several physiological variables such as blood pressure, heart rate, respiration and skin conductivity while a series of questions is being asked, in an attempt to detect lies. ...
