The skin is an amazing and versatile organ. It’s not only smooth and often nice to look at, but also helps to regulate many functions of the body. It acts as a barrier against environmental threats, contains nerve cells that detect changes such as temperature and pressure, can heal itself, and (ideally) keeps your body […]

What Can Electrodermal Activity Measurements Tell You?

Electricity is everywhere. It’s in the air, it’s deep inside the earth, and it’s even in our bodies. Our cells conduct electrical currents, and electricity is needed for the body and the brain to communicate.   The skin also conducts electricity in the body. Thanks to scientific advancements, variations in the electrical characteristics of the […]

4 Ways to Measure Galvanic Skin Response (GSR)

Galvanic skin response, or GSR, is a form of biofeedback that measures changes in the electrical resistance of the skin. The process of measuring GSR involves introducing external items such as images, sounds, questions, foods, or products and then observing how skin resistance changes in comparison to a baseline reading.   GSR measurement has a […]

Galvanic Skin Response Studies Reveal Distinct Correlation Patterns
