TI  - From Grids to Places
Y1  - 2006/08//
N2  - Hafting et al. (2005) described grid cells in the dorsocaudal region of the medial enthorinal cortex (dMEC). These cells show a strikingly regular grid-like firing-pattern as a function of the position of a rat in an enclosure. Since the dMEC projects to the hippocampal areas
containing the well-known place cells, the question arises whether and how the localized responses of the latter can emerge based on the output of grid cells.
Here, we show that, starting with simulated grid-cells,
a simple linear transformation maximizing sparseness
leads to a localized representation similar to place
fields.
