Representation of Spatiotemporal Information in Human Episodic Memory and Navigation

Summary

Neural diseases such as stroke can have distinct effects on the ability to navigate and orient compared to remembering daily events like when one last took medicine. This proposal seeks test rival hypotheses regarding the neural mechanisms underlying commonalities and differences in navigation and event-related memory, particularly as they relate to pre-existing knowledge. Such mechanistic insight could help inspire therapies that could be used to bolster intact brain function in a compensatory manner following strokes or other neural insults.
