Looking for Emotions on a Single EEG Signal

Abstract: This work aims at demonstrating that it is possible to detect emotions using a single EEG channel with an accuracy that is comparable to that obtained in studies carried out with devices that have a high number of channels. In this article the Neurosky Maindwave device, which only a single electrode at the FP1 position, the MatLab and the IBM SPSS Modeler were used to acquire, process and classify the signals respectively. It is remarkable the accuracy achieved in relation to the inexpensive hardware employed … Show more

“…Namely, stress produces an increase in the electrical activity of the sympathetic nervous system (SNS), that along with the inhibition of the parasympathetic nervous system (PSNS), makes changes in heart rate (HR), breathing rate (BR), electrodermal activity (EDA), and skin temperature (ST). Several papers have directly analyzed emotions through EEG [49][50][51][52][53] or studied their effects on variables such as HR [54,55], EDA [55,56], BR [57], or ST [56]. Combining several of these signals in a multimodal approach may benefit detection accuracy [58].…”

“…We applied the algorithm published in [ 45 ] for the detection of single blinks. It is based on obtaining two main features from the raw EEG signal: (1) the difference between the maximum and minimum value in the epoch and (2) the energy of the ’blink-free’ EEG signal resulting from removing the baseline obtained by applying a Savitzky–Golay low-pass filter (order 2 and length 35) to the EEG epoch.…”
