- 소개/요약Though it is plausible that meditation and attention training technique (ATT) re-quire similar attention control, empirical research on the similarities and differences between these methods is limited and further required. As a rst step toward llingthis research gap, we investigated the brain activity of experienced meditators while they engaged in ATT and compared the results with those of previous research. Eight healthy right-handed persons with considerable experience in meditation participatedin this study. Electroencephalograms (EEG) of all participants were recorded during the three conditions included in ATT, as well as in an eyes-closed resting state. Us-ing sLORETA (standardized low-resolution electromagnetic tomography) software to computesignal source location, we investigated brain activity during each condition of ATT. During the attention switching condition and divided attention condition, when compared with the rest, signi cant increases of gamma frequency, known to be closely correlated with brain activation, were observed in the right dorsolateral prefrontal cortex (DLPFC). This result is consistent with that of the previous neuroscienti c study of meditation, and this activation may reect maintenance of sustained attention. Larger meditator group and continuing the investigation that compares ATT and meditation are needed.
