Software and Datasets


    Estimate and visualize brain activities from MEG and/or EEG data. It can use various prior information on brain activities to improve their estimation accuracy. It can also visualize signal flows across brain regions.
  • Sparase Estimation Toolbox
    Build a classification or regression model by automatically discarding non-relevant brain activities.


  • OPM-MEG, SQUID-MEG, and EEG (OSE) dataset
    The “OPM-MEG, SQUID-MEG, and EEG (OSE)” dataset aims to disseminate a new type of magnetoencephalography (MEG) device, an optically pumped magnetometer (OPM), which enables a wearable MEG measurement system. This dataset provides OPM-MEG, SQUID-MEG, and electroencephalography (EEG) data. Using this dataset, you can test the source imaging from the OPM-MEG data and compare the results with those from the conventional SQUID-MEG and EEG data.
    – 5 subjects
    – Measurements: OPM-MEG, SQUID-MEG, EEG, and T1-weighted image (T1)
    – Tasks: Motor, Auditory, Somatosensory, and Resting-state
