The term EDA is often used synonymously in academic literature to refer to its usage as a non-invasive biomarker to investigate physiological arousal. EDA is generally recorded using two small electrodes and are usually [1], [2] can be placed on the:

These electrodes complete a circuit across the skin – the skin acts as a variable resistor – and then measure changes in skin conductance (see note for more information on what variables EDA monitors). After the EDA signal is collected from the electrodes, the signal is typically (by convention) decomposed into skin conductance level SCL and skin conductance responses SCR (click links to see definitions of both).
