216 – Electrodermal Activity (EDA/GSR) Scoring Methods

Several methods can be used to score the number of electrodermal response (galvanic skin response) changes. In all cases, it is assumed that the EDA (GSR) signal was sampled in DC mode. This note describes post-acquisition scoring, but the same technique can be applied in real time using calculation channels.
