場所法記憶の想起時における脳活動の等価電流双極子による推定(一般講演4A)

We measured electroencephalogram (EEGs) in recalling long term memories (Method of Loci) consolidated by mnemonics. We analyzed brain activities using the equivalent current dipole localization (ECDL). ECDs were localized to the left supramarginal gyrus (SMG), to the middle temporal gyrus (MTG) called Wernicke's area, and to the left middle frontal gyrus (MFG) called Broca's area. After the Broca's area, ECDs were localized to the prefrontal area (PFA), and then to the MFG and the inferior frontal gyrus (IFG) of both hemispheres. In comparison with the previous fMRI studies by Ichihashi et al., some ECDs were localized to the same areas. Furthermore, we clarified the transition of brain activities by the time series in recalling task by the Method of Loci from the presented sentence.
