･This study aimed to show that some EEG activities are reflective of a depressed mood and to use this finding to develop practical biomarkers for early depression detection.
･As a first step, we conducted a pilot study to investigate the generality of the preliminary results, mainly in healthy participants. We found that indicators of depressed mood were correlated with the occurrence frequency of EEG phase resetting.
･The results may contribute to a better understanding and treatment of depression.
