Figure 5.

Comparison between pairwise correlations of pyramidal cells recorded during SWS before and SWS after a wheel-running session. Each data point in A corresponds to one cell pair. Pairs with high (>0.05) and low (<0.05) correlations in the awake state are shown by filled red circles and open triangles, respectively. (B) Mean cross-correlation (±50 msec) for neuron pairs during sleep before and after wheel running (awake). Data are shown separately for neuron pairs with high (red) and low (black) awake correlation. Neuron pairs with high and low awake correlations were significantly different in both sleep sessions (*, P < 0.01). The sleep before vs. sleep after comparison was also significant (+, P < 0.05) for cell pairs with high awake correlation.
