a Slow-wave peak-triggered average population firing-rate in PL5 (in 3 ms bins, n = 8 rats). Slow-waves were separated into tertiles based on their amplitudes within each rat, and the firing rates were normalised to the mean in periods of [−2,000 ms, −1500 ms] and [+1500 ms, +2000 ms] from the slow-wave peaks. The mean PL5 LFP waveforms are presented on the top. The troughs of the firing rates precede the peaks of the cortical slow-waves, as observed previously32,36. b Slow-wave peak-triggered average of HFO and SWR occurrence rates. The lines and shaded areas indicate the mean and SEM, respectively (n = 15 and 14 rats for HFOs and SWRs, respectively). c Slow-wave peak-triggered average BLA–PL5 and vCA1–PL5 coactivation strength. Normalised coactivation strength was obtained as a z-score of the results in periods of ± 2000 ms range. The numbers of pairs analysed are summarised in Supplementary Table 4.
