Abstract
Rodents have the ability to infer the spatial relationship between locations that cannot be directly perceived. Traditionally, the neural substrate of this ability has been considered to be place cells; hippocampal neurons which fire when the animal occupies a specific location. However, we propose that a second type of cell, the head direction (HD) cell, may be better suited as a basis for navigation between locations. The proposed project will assess the relationship between the firing direction of HD cells and the accuracy of an animals navigation, and will compare the responses of HD cells and place cells recorded simultaneously. The knowledge gained will extend our understanding of the neural bases of spatial cognition.
