人脑连接组计划首次发布脑磁图数据集
3月4日,华盛顿大学与明尼苏达大学作为人脑连接组计划(Human Connectome Project ,HCP)的联合参与者首次发布脑磁图(Magnetoencephalography ,MEG)数据集。MEG1(HCP MEG Initial)为14位(均为同卵双胞胎)健康成人被试在静息态(rMEG)及感觉、运动和认知测量3种任务下的10组完备的高质量数据(数据类型见正文下方)。
通过ConnectomeDB数据库可获取约300GB的MEG1数据,其中大部分HCP影像和行为数据注册后可供全球研究人员获取,下载地址:

HCP MEG专有分析软件“megconnectome software version 1.0”经注册可免费下载使用,

更多信息可通过HCP MEG1数据参考手册获得,

MEG1 包含如下数据类型:
• raw, unprocessed MEG data in 4D Neuroimaging format
• co-registration information (in the form of transformation matrices) that allow coordinate transformations between individual subject MEG coordinate systems and the MNI coordinate system
• volume conduction model of the head (in MATLAB format)
• regular 3-D source models (in MATLAB format)
• E-Prime log files (tab-delimited and as Excel spreadsheets)
• lists of bad channels and bad segments
• sets of independent components (each comprising the time course and the sensor map) together with the related classification output
• cleaned channel-level processed data aligned to stimulus and response onsets (for the task data) or segmented in short pieces (2 sec epochs for the resting state data)
• averaged event-related fields and time-frequency estimates of power (for the task data)
• averaged power spectra (for the resting state data)
