Electrodermal Activity (EDA) Events Add-on

The Electrodermal Activity (EDA) Analysis add-on for the OpenSignals (r)evolution software is the ideal software extension for the biosignalsplux EDA sensor and the BITalino EDA sensor, also commonly known as Galvanic Skin Response (GSR) sensor.

Electrodermal responses are phasic changes of the electrical properties of the skin (e.g. conductance) caused by alterations in the sweat secretion and sweat gland activity as the result of changing sympathetic nervous system activation.
