    Mapping and understanding of correlated electroencephalogram (EEG) responses to the newsvendor problem by Nghi Cong Dung Truong, Xinlong Wang, Hashini Wanniarachchi, Yan Lang, Sridhar Nerur, Kay-Yut Chen, Hanli Liu

    Published 2022-08-01
    “…Finally, the CorrCA forward models, which represent the scalp projections of the brain activities by the maximally correlated components, were further translated into source distributions of underlying cortical activity using the exact Low Resolution Electromagnetic Tomography Algorithm (eLORETA). Our results revealed strong and significant correlations in EEG signals among multiple subjects and trials during the more difficult decision-making task than the easier one. …”
