DESCRIPTION:Mammalian grid cells discharge when an animal crosses the poin
 ts of an imaginary hexagonal grid tessellating the environment. In this ta
 lk\, I will show how animals can use this code by reading out the grid-cel
 l population activity across multiple spatial scales. The theory explains 
 key experimental results\, makes testable predictions for future physiolog
 ical and behavioral studies\, and provides a mathematical foundation for t
 he concept of a "neural metric" for space. For goal-directed navigation\, 
 the proposed allocentric grid-cell representation can be readily transform
 ed into the egocentric goal coordinates needed for planning movements. The
 se results show that the grid-cell code provides a powerful and highly fle
 xible neural substrate for spatial cognition.\n\n
