• Skin conductance (SCR)
• Galvanic skin response (GSR)
• Electrodermal activity (EDA)
• Linear time-invariant filter (LTI)
• Area under the curve (AUC)

Autonomic arousal is often indexed by spontaneous fluctuations in skin conductance Here, we derive a simple measure of sympathetic arousal, using a convolution model of how sudomotor bursting causes fluctuations in skin conductivity Under this model, the time-integral of measured conductance is proportional to the frequency and amplitude of sudomotor bursts We demonstrate the validity
