Abstract: Electroencephalography (EEG) has received much attention because it provides comprehensive information of human perception and is relatively space- and cost-effective compared with the other functional brain imaging methods. In this paper, we present an approach to model undirected and directed cross-regional dependence of EEG signals with convolutional neural networks (CNNs). It considers the brain connectivity that measures simultaneous activation of different brain regions. Furthermore, the spatial arrangement of EEG electrodes is examined. We verify the effectiveness of the method for EEG-based emotion recognition.

TL;DR: We design connectivity matrix to model cross-regional dependence of EEG signals with CNNs.
