Simultaneous measurement of mental sweating dynamics by electrodermal activity and optical coherence tomography
Electrodermal activity (EDA) is reflecting the activity of the sympathetic nervous system. And Optical coherence tomography (OCT) have revealed sweating dynamics inside the stratum corneum on fingertips. By analyzing the OCT and EDA signals of the fingertip captured simultaneously, it was clarified that the EDA had a latency to detect mental sweating response. As a result, it is hypothesized that EDA has mainly captured the sweating which appears from the stratum corneum as the change of the conductance.
