Electrodermal response

See also Galvanic skin response.

The electrodermal response is measured by monitoring the conductance of the skin -- usually on the fingers, palm or bottom of the foot. This conductance varies as the amount of sweat in the glands changes. These changes are often the result of changes in arousal and/or changes in sympathetic nervous system activity.

There are several different parts of the electrodermal response that can be examined, including the magnitude of the response, the rate of rise, rate of recovery, etc.
