postbehavioral

First, we assessed reactivation of neuronal patterns using an explained variance (EV) method based on the spike correlations of cell pairs across all simultaneously recorded neurons Sparse hippocampal and ventral striatal ensemble firing patterns during track running and postbehavioral rest.

Cross-correlogram analysis revealed that joint reactivation is not restricted to neuronal pairs that exhibit overlapping firing fields; peaks that were separated by up to about 4.5 s during behavior were found to recur during postbehavioral rest.

This quantity is expressed in the EV measure: in which R1 and R2 represent the pre - and postbehavioral rest episodes, respectively, and for example, rTrack, R2 equals the matrix correlation coefficient between the Track and Rest 2 pattern.

The relative time offsets of peaks were preserved from track running to postbehavioral rest.

In the topmost example, a secondary peak during track running is recurring in postbehavioral rest (indicated by the asterisk [*]).

Accordingly, the strength of coactivation of a place cell and a reward-related VS cell, expressed in the Pearson correlation coefficient, was positively correlated to the degree of spatial overlap of the firing fields on the track during task performance and postbehavioral sleep, but not during prebehavioral rest (prebehavioral rest: n.s.; track running:

Figure 3C), the preservation of firing order suggests that replay should be dominated by activity patterns in which HC firing largely precedes VS firing, both during track running and postbehavioral rest.

The peak offsets during track running were correlated to the peak-offsets during postbehavioral rest (one rest episode were included in analysis.

Second, the timing of the peaks during track running and postbehavioral rest was correlated in the cross-correlogram analysis (
