<font size=4><b>At the very core of our ability to interact in the
environment is our perception of spatial relationships. Spatial cognition
is distributed across several brain regions and takes on multiple forms
which can be defined by their frames of reference. In this talk, the
presentation of experimental work will contrast the allocentric or
‘world-centered’ mapping of spatial position observed for hippocampal
neurons with the ‘route-centered’ mapping of position observed in
parietal cortex. In considering spatial activity patterns for each of
these structures, special attention will be given to pattern overlap as
it occurs across behavioral and environmental contexts. The potential
impact of such overlap on the organization of episodic memory and
behavioral sequences will be discussed.</font></b></body>
