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.

BIOPAC recommends the following paper as an excellent reference for guidelines for EDA, GSR, EDR, SCL, and SCR:

The Mobita 32-Channel EEG recording system was used in research examining if physiological data can be used to predict truly random events that correspond to perceptual stimuli. Baumgart, et al. from the University of California Santa Barbara utilized a quantum random number generator (qRNG) to choose from three randomized conditions: light, sound, and no stimulus. […]
BIOPAC provides software and hardware that allow for research teams to record and analyze respiration activity in physiological experimentation. Here are a few notable studies in monitoring respiration and cardiovascular activity. The coupling between peripheral microcirculation and slow breathing: The purpose of this study was to investigate the coupling of breathing movements and microcirculatory blood […]
