Forward and reverse temporal sequences during ripples reflect distance representations of place cells on the track. (a) Cross-correlograms (CCGs) of forward (preplay) and reverse (replay) events with CA1 sharp-wave ripple events. (b) Temporal offsets between spikes of neuron pairs during significant forward (+) and reverse (o) events were correlated with distance representations between place-field peaks on the track. (c) Temporal offsets of cell pairs were related between track running (‘theta-scale time compression’9) and forward (preplay) and reverse (replay) events.
