    "abstract": "The hippocampus has the capacity for reactivating recently acquired memories\n[1-3] and it is hypothesized that one of the functions of sleep reactivation is\nthe facilitation of consolidation of novel memory traces [4-11]. The dynamic\nand network processes underlying such a reactivation remain, however, unknown.\nWe show that such a reactivation characterized by local, self-sustained\nactivity of a network region may be an inherent property of the recurrent\nexcitatory-inhibitory network with a heterogeneous structure. The entry into\nthe reactivation phase is mediated through a physiologically feasible\nregulation of global excitability and external input sources, while the\nreactivated component of the network is formed through induced network\nheterogeneities during learning. We show that structural changes needed for\nrobust reactivation of a given network region are well within known\nphysiological parameters [12,13].",
