Investigating the neuronal basis of homing based on path integration

Presented by: Kevin Allen
Path integration refers to the ability of an animal to keep track of its position by integrating self-motion cues. Studies in rodents and humans point to an essential role of the hippocampal and parahippocampal areas in this process. These brain areas contain numerous types of spatially selective neurons, including place and grid cells. How these cells contribute to navigation based on path integration has remained unclear, as these cells are usually not recorded in animals navigating using path integration. I will present a new homing task for mice that we developed to characterize the activity of spatially selective neurons in mice navigating using path integration. I will describe how the activity of hippocampal place cells might contribute to homing based on path integration.
