Outline of Final Research Achievements

In order to elucidate the human brain mechanism, we developed a multimodality neuronal activity measurement system for simultaneous measurement of magnetoencephalography (MEG) and electroencepalography (EEG) using optically pumped atomic magnetometers (OPAM). It was confirmed that visual evoked responses with OPAM-MEG and EEG can be measured simultaneously in our constructed environment. In addition, we have developed a simultaneous measurement system by multi-channel OPAM and EEG, head mount, multimodal data analysis flow, and connectivity analysis tool, which can contribute to a future multimodal neuroimaging system without any large-scale cooling devices.
