Galvanic skin conductance (GSC) increases prior to sweat reaching the skin surface [1], indicating
pre-secretory sweat gland activity. Sweat travels through the duct and penetrates the stratum
corneum (SC) causing epidermal hydration (HYD). Boucsein [2] 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 [3]. The aim of this experiment is to determine the extent to which
these contribute to the value of GSC.
