AbstractEmotion can be regarded as a special brain status and it can be captured by Electroencephalography (EEG) via deploying number of channels all over the scalp. To find out the characteristics of emotional responses, the scalp level connectivity is one of the interests that considered. Nevertheless, to distinguish the significant EEG channels, which can imply the special regions at scalp level, has not yet been studied well. Therefore, in this work, we aim to identify the representative channels towards different emotional status by considering the connectivity derived from the values of coherence and correlation. In this purpose, DEAP, an online database has been investigated. Certainly, the emotional status can be evaluated on the valence-arousal (V-A) space and here, four groups contain HVHA, HVLA, LVHA, and LVLA have been studied. The results from 16 subjects show that the EEG channels AF3, F7, P7 and O1 have higher percentages in term of the connectivity and they could be considered as the representative channels in this case. Such findings could be useful to understand the scalp responses in emotional status.
