[Dynamics of electrodermal activity during changes in the hydration of the epidermis: theoretical model]

The presented theoretical model explains three ways of epidermal hydration changes. These ways are; water movement from both dermal layer and sweat gland ducts to the epidermis, and then, from the epidermis to the air. Epidermal hydration changes influenced electrodermal activity. It was revealed, that epidermal hydration changes impact both amplitudes and latencies of the electrodermal activity.
