Features of hippocampal population activity during sharp wave-ripple states. Parameters of the model are given in column HP of Table 1A recent intracellular study (English et al., 2014) recording from CA1 neurons in awake mice found parameters similar to our previous estimates. Using the parameters found in that study – $r^{+}=12.8$ Hz, $r^{-}=2.85$ Hz (Table 1 of English et al., 2014), $2\overline{u}=5$ mV and ${\overline{\mathrm{\Sigma }}}_{ii}=4$ mV${}^2$ (Figure 3A of English et al., 2014) yielding $g=5$ Hz and $\beta =0.3$ mV${}^{-1}$ – did not influence our results (not shown).
