Discrimination of a Pleasant and an Unpleasant State by Linear Complexity of EEG

뇌전위의 Linear Complexity 분석에 의한 쾌, 불쾌상태의 구분

Liner complexity(LC), which could quantify the modal structure, were calculated from electroencephalograms(EEGs) in four states such as a pleasant and relaxed, a pleasant and aroused, an unpleasant and relaxed, and an unpleasant and aroused state. Each state was evoke by visual stimuli of relaxed or aroused state, LC could discriminate statistically state(t-test; p<0.01). LCs in pleasant states were larger than those in unpleasant ones.
