Galvanic skin conductance (GSC) increases prior to sweat reaching the skin surface , indicating pre-secretory sweat gland activity. Sweat travels through the duct and penetrates the stratum corneum (SC) causing epidermal hydration (HYD). Boucsein  claimed that SC hydrates first before sweat is released onto the skin surface. GSC is influenced by sweat within the glands, HYD and sweat on the skin surface . The aim of this experiment is to determine the extent to which these contribute to the value of GSC.
