Electrodermal Activity
Ferhan ESEN*
*Yrd.Doç.Dr., Osmangazi Üniversitesi Tıp Fakültesi Biyofizik AD, ESKİŞEHİR Electrodermal activity (EDA) is defined as an electrical phenomena which originates from the sweat gland, epidermal and dermal layers in the skin and can be recorded with the electrodes placed on the special skin site.
Eccrin sweat gland which is important for the electrodermal activity is innervated by the sympathetic cholinergic fibers and the activation of these fibers increases the sweat secretion. As a result of this activation, skin resistance changes. Experimental evidence concerning the central nervous system elicitation of EDA points to the existence of two different origins: a limbic-hypothalamic source labelled EDA-1 and a premotor-basal ganglia source labelled EDA-2. Therefore, it is suggested that EDA can be indirectly used for the assesment of sympathetic nervous system activity. Furthermore, it is also expressed that bioelectrical activity on the skin can be used as an indicator of the central nervous system activation.Keywords: Electrodermal activity (EDA),
