p596fig16.30 Data (top row) and simulations (bottom row) of spatial phases of learned grid and place cells.<BR>||  Spatial phases of learned grid and place cells (Hafting etal 2005).  Data: Cross-correlogram of rate maps of two grid cells;  Distribution of phase difference: distance from origin to nearest peak in cross-correlogram.  Simulations: Grid cell histogram of spatial correlation coefficients;  Place cell histogram of spatial correlation coefficients.
