Thanks to its milli-second order temporal resolution, it is employed by various studies. However, the measuring cost of a conventional device using SQUID-type sensors is expensive due to a liquid helium requirement, and it is the primary bottleneck. Recently, the optically pumped magnetometer (OPM) device has been under the global spotlight. It enables a cerebral magnetic field measuring system without any expensive medium.<\/p>\n\n\n\n<p>As a part of NICT-itaku project (#209), we are building the OPM measurement system. We validated our system by comparing the SQUID-MEG and the OPM-MEG using multi-task experiments with several subjects. We observed well-known waveforms for both OPM-MEG and SQUID-MEG recordings for each task in accordance with the previous SQUID-MEG studies. As a result of the current source reconstruction, sources were localized at places consistent with the conventional knowledge of each task for both devices. These results confirm that our OPM-MEG system records the cerebral magnetic field with low-cost and sufficient quality.<\/p>\n","protected":false},"featured_media":0,"template":"","acf":[],"_links":{"self":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/japanese\/wp-json\/wp\/v2\/event\/1887"}],"collection":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/japanese\/wp-json\/wp\/v2\/event"}],"about":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/japanese\/wp-json\/wp\/v2\/types\/event"}],"wp:attachment":[{"href":"http:\/\/cinetjp-static3.nict.go.jp\/japanese\/wp-json\/wp\/v2\/media?parent=1887"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
