One current explanation of the view independent representation of space by the place-cells of the hippocampus is that they arise out of the summation of view dependent Gaussians. This proposal as- sumes that visual representations show bounded invariance. Here we investigate whether a recently proposed visual encoding scheme called the temporal population code can provide such representa- tions. Our analysis is based on the behavior of a simulated robot in a virtual environment containing speci(cid:12)c visual cues. Our re- sults show that the temporal population code provides a represen- tational substrate that can naturally account for the formation of place (cid:12)elds.
