Topological mapping of space in bat hippocampus

Understand

Mammalian hippocampus plays a key role in spatial learning and memory, but the exact nature of the hippocampal representation of space is still being explored.

• Recently, there has been a fair amount of success in modeling hippocampal spatial maps in rats, assuming a topological perspective on spatial information processing.
• In this paper, we use the topological model to study $3D$ learning in bats, which produces several insights into neurophysiological mechanisms of the hippocampal spatial mapping.
• First, we demonstrate functional importance of the cell assemblies for producing accurate maps of the $3D$ environments.
