A dataset of human fMRI/MEG experiments with eye tracking for spatial memory research using virtual reality
Cross modal based on virtual reality scene ( magnetic resonance 、 Magnetoencephalogram 、 Eye movement ) Open source data set for human spatial memory research
Bo Zhang( Zhang Bo , Postdoctoral researcher of Zhiyuan Research Institute ),Yuji Naya( Najia Yongzhi , Professor of Peking University )
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 .
chart 1: Introduction to experimental paradigm .a, The task scenario consists of 3 It's made of two objects , Form a specific spatial relationship . The subjects recognize the scene from the first person perspective .b, Experimental paradigm , Subjects complete scene recognition in turn (Walking period), Self orientation (Facing period), And object positioning (Targeting period) Mission .c, Schematic diagram of object spatial relationship and subject motion direction .d, Aerial view diagram in the task of locating objects .
