Data in Brief
|July 5, 2022
Summary
This study presents a novel dataset of brain imaging and behavioral data to explore how humans create and use cognitive maps in virtual environments. The data aids in understanding spatial memory and neural network functions.
Area of Science:
- Neuroscience
- Cognitive Science
- Computer Science
Background:
- Understanding the neural basis of spatial cognition is crucial for both human and artificial intelligence.
- Previous research has explored cognitive maps, but integrated neuroimaging and behavioral data are limited.
Purpose of the Study:
- To investigate the neural representation and dynamics of cognitive maps using fMRI and MEG data.
- To examine neural networks involved in representing targets within and outside the visual field.
- To provide a dataset for developing bioinspired deep neural networks for spatial processing.
Main Methods:
- Collected whole-brain fMRI and MEG data, eye-tracking, and behavioral records from healthy adults in a virtual spatial-memory task.
- Acquired fMRI BOLD and T1-weighted images using a 3T Siemens Prisma scanner.
- Acquired MEG data using a 275-channel MEG system.
Main Results:
- The dataset captures neural representations of object spatial relationships and self-location.
- It reveals neural dynamics during shifts in spatial task demands (localization to memory).
- The data allows for the study of neural networks for visual field representation.
Conclusions:
- This dataset offers a valuable resource for studying human spatial cognition.
- It can advance the development of AI systems with enhanced spatial processing capabilities.
- Further research can leverage this data to explore diverse neural mechanisms.
