Electrodermal activity (EDA) is a sensitive measure of sympathetic nervous system activity. It is used to describe changes in the skin electrical properties. This review aimed to show advantages of simultaneously recordings EDA parameters at the same skin site over other recordings. The literature databases Science Web, Google Scholar was searched using terms ‘electrodermal activity’, ‘sequentially recording’, ‘simultaneously recording’, ‘skin conductance’, ‘skin potential’, and ‘skin susceptance’. Articles that include sequentially and/or simultaneously recording EDA parameters were analyzed. The review presents a description of the oldest and current methods used for recording EDA parameters and an explanation of the newest techniques used in EDA researches. Although sequentially recordings are predominant and wide spread, much effort have been made to simultaneously record skin conductance (SC) and skin potential (SP), and recently researchers realized capability of simultaneously recording SC, SP, and skin susceptance (SS) at the same skin site. The advantage of simultaneous over the sequence measurements is that the latter must be manually time realigned when measured by different instruments which means time consuming. Although the simultaneous measurements are used exclusively for research purposes at this stage, this may open horizons in the modern trends of psychophysiology applications in the near future.
