Is EDA the same as GSR?

GSR (short for either Galvanic Skin Response, Galvanic Skin Reaction, or Galvanic Skin Reflex) is an old and often misleading term that has been used to refer to a variety of electrodermal phenomena. GSR can refer to either resistance, conductance, phasic responses, general electrodermal phenomena, or to other things. Over the years, the skin has been shown to be much more complex than a “galvanic element”. Given the potential for confusion the use of the term has declined in favor of more descriptive terms like EDA.
