brief introduction ：

The open source data set of human spatial memory research is a whole brain including the records of human subjects when they perform virtual reality games fMRI（ Functional magnetic resonance imaging ）、 cortex MEG（ MEG image ）、 Eye tracking data , And behavioral records of multimodal data sets . The experimental paradigm is based on Unity Virtual reality spatial memory task , The subjects completed scene recognition in turn from the first person perspective , Self orientation , And object location tasks . Data set containing 31 Adult human subjects , among 19 Participated in fMRI experiment ,12 Participated in MEG experiment （fMRI experiment ：12 Famous woman ,7 Men ;MEG experiment ：4 Famous woman ,8 Men ）. The average ages of the subjects were 24.9 year （MRI：18-30 year ） and 22.5 year （MEG：19-25 year ）.fMRI（BOLD and T1 Weighted images ） and MEG（ Brain magnetism and T1 Weighted images ） Through Siemens Prisma 3T Scanner （Siemens, Erlangen, Germany） and 275 passageway MEG System （CTF MEG,Canada） collection . With eye movement data , This data set can be used for human vision 、 Research on neural mechanism of spatial memory , And it can be used in the research of neural networks based on biological inspiration , It helps to improve the machine's visual space recognition and perception ability .
