Headmodels

The HeadModel folder contains the headmodels after the coregistration of T1 images and the MEG data for 39 participants. For 3 participants who do not have T1 images, the MNI template brain (Montreal, Quebec, Canada) was used. The headmodel was obtained by using a fieldtrip function ft_prepare_headmodel.m with cfg.method = 'singleshell' (https://www.fieldtriptoolbox.org/reference/ft_prepare_headmodel/).HeadModel文件夹包含了39名被试的T1图像与脑磁图（MEG）数据经共配准（coregistration）后得到的头模型。针对3名无T1图像的被试，采用了位于加拿大魁北克省蒙特利尔的MNI标准脑模板。所有头模型均通过FieldTrip工具箱的ft_prepare_headmodel.m函数生成，配置参数cfg.method设为'singleshell'（单壳层），具体参考文档见https://www.fieldtriptoolbox.org/reference/ft_prepare_headmodel/。
