Place field sizes, and predicted uncertainty, on a circular track with objects.

<p>The blue lines show the smoothed place field sizes (10-point moving average), normalized to a mean of 0 and variance of 1, and the red lines show the location uncertainty predicted by the Bayesian model. The minima of the red lines correspond to the black squares marking the positions of the objects on the track, since the location uncertainty is lowest near to an object and highest when the rat is far from the objects. Pearson's correlation coefficient between the recorded place field sizes and the predicted uncertainty was for rat 1 and for rat 2. The proportions of explained variance were for rat 1 and for rat 2.
