While the primary goal of the eccrine sweat glands is of course thermoregulation, the eccrine glands on the hand and feet have been theorized to function mainly as an aid for grasping. The eccrine glands, on the other hand, cover most of the body, are most dense on the palms of your hands and the soles of your feet, and have been well studied and documented in various studies of GSR. Furthermore, very little is currently known about the GSR responsiveness of these glands. Apocrine glands, which are relatively unstudied, are focused around hair follicles, and are primarily located in the armpits and genital areas. ItвЂ™s important to note that there are two different types of sweat glands on the skin: eccrine and apocrine glands.

As a result, the skin is constantly receiving signals from the brain and the rest of the body, which is one of the reasons why the skin can function as a helpful indicator of various states of the body. The authors point out that the skin is the largest organ of the body and accomplishes a wide range of dynamic functions.

While we often think about galvanic skin response, or electrodermal activity, as being principally associated with lie detector tests, the authors of a chapter in the Handbook of Psychophysiology point out that вЂњmeasures have been applied to a wide variety of questions-ranging from basic research examining attention, information processing, and emotion to more applied clinical research examining predictors and/or correlates of normal and abnormal behavior.вЂќ 1ДЄlthough this chapter focuses almost exclusively on a variety of experiments that look at GSR in the context of physical responses to psychological states, a few studies are reviewed and discussed that are important to understanding ZYTO biocommunication technology and services.
