Think local, act global: How do fragmented representations of space allow seamless navigation?
Paul A. Dudchenko, Emma R. Wood, Roddy M. Grieves · Behavioral and Brain Sciences · 2013
In this commentary, we highlight a difficulty for metric navigation arising from recent data with grid and place cells: the integration of piecemeal representations of space in environments with repeated boundaries. Put simply, it is unclear how place and grid cells might provide a global representation of distance when their fields appear to represent repeated boundaries within an environment. One implication of this is that the capacity for spatial inferences may be limited.
