This application note explains how to record electrodermal activity (EDA/GSR) and observe electrodermal response (EDR) changes with the EDA100C Electrodermal Activity amplifier, GSR100C Galvanic Skin Response amplifier, or TEL100C telemetry module of the MP System (with MP100 or MP150). The MP System can measure both subtle and sudden changes in electrodermal activity, based on your protocols.
BIOPAC recommends the following paper as an excellent reference for guidelines for EDA, GSR, EDR, SCL, and SCR:

StimTracker Duo. StimTracker Quad MARK. SYNC. AUDIT. StimTracker Duo and Quad autonomously detect the onset of events to avoid operating system delays. The Quad adds direct TTL output, support for vocal response onset (voice key), more light sensors, and the option to install a Raspberry Pi board. Onset of Auditory Stimuli – Pass the audio via StimTracker, set […]
Science Night at Adams Elementary (Santa Barbara, CA) encourages students to discover, play, explore and learn about the importance of science and engineering in daily life. BIOPAC set up a BioNomadix Wireless Smart Center to allow students to record their heart rate. Electrodes were placed on students and leads were connected to a wireless transmitter that sent data […]
Recent developments regarding electric stimulation and mental processing have lead to interesting developments in psychophysiology and physiological sciences. The following studies look at developments in how we potentially care for and understand solutions to issues with mental health, as well as new ways to monitor electrical stimulus on participants. The ventromedial prefrontal cortex (vmPFC) is […]
