Electroencephalography (EEG) is one of the most commonly used measures in neuroscience and psychophysiology research for studying functional information of brain activity such as cognition and emotion. However, because of lack of convenient methods to measure EEG, it is difficult to use in everyday situations. The electrodermal potential (EDP) can be used to monitor brain activities. This study investigated the correlation between scalp acquired EEG and EDP from the body below the head, for two distinctive cognitive statuses of relaxation and attention. The results showed that theta power decreases while beta power increases in the attention state compared to relaxation from EDP. We also obtained 84.2 % of classification accuracy to discriminate attention-relaxation states using EDP signals, while obtaining 83.9~89.3 % of the classification accuracy using a single channel EEG.
