Extended Data Fig. 8: Low activity cells with increased burst spiking following CPP exhibited stronger place field coherence and spatial information content.

a,b, Cumming estimation plots showing for low (blue colours) and high (red colours) activity cells the effect size in changes of place field coherence (a) and spatial mutual information (b) between exposure and re-exposure in the CPP task. The most burst spiking cells of both subpopulation (top 40% of bursting index distribution) in the re-exposure session are considered. Note that low, but not high, activity cells have significantly higher spatial coherence (a) and mutual information (b) during re-exposure after CPP. c-h, Similarly, the place field coherence (c,e,g) and the spatial mutual information (d,f,h) of low and high activity principal cells is shown for the other tasks including exposure and re-exposure sessions. Low and high activity cells selected in the same way as in the CPP task dataset (a,b) to allow for comparison. For all Cumming estimation plots: black-dot, median (for skewed distributions) or mean (for normal distributions) as indicated; black-ticks, 95% confidence interval; filled-curve: bootstrapped sampling-error distribution.
