Inhomogeneous pattern sizes lead to dynamic instability during sequence replay. In all graphs, we show the fraction $m_t/M_t$ of hits (blue) at time step t and the fraction $n_t/(N-M_t)$ of false alarms (red) during the replay of a sequence of length $Q=100$, using the mean field model of equations (9) and following. Left to right: increasing inhomogeneity ${\sigma }_{\varphi }$. Bottom to top: increasing firing thresholds θ. Other parameters were $N={10}^5$, $c_m=0.1$, $c=0.05$ and ${\varphi }_0=0.01$
