  bibo_abstract:
  - Memories are thought to be stored in neural ensembles known as engrams that are
    specifically reactivated during memory recall. Recent studies have found that
    memory engrams of two events that happened close in time tend to overlap in the
    hippocampus and the amygdala, and these overlaps have been shown to support memory
    linking. It has been hypothesized that engram overlaps arise from the mechanisms
    that regulate memory allocation itself, involving neural excitability, but the
    exact process remains unclear. Indeed, most theoretical studies focus on synaptic
    plasticity and little is known about the role of intrinsic plasticity, which could
    be mediated by neural excitability and serve as a complementary mechanism for
    forming memory engrams. Here, we developed a rate-based recurrent neural network
    that includes both synaptic plasticity and neural excitability. We obtained structural
    and functional overlap of memory engrams for contexts that are presented close
    in time, consistent with experimental and computational studies. We then investigated
    the role of excitability in memory allocation at the network level and unveiled
    competitive mechanisms driven by inhibition. This work suggests mechanisms underlying
    the role of intrinsic excitability in memory allocation and linking, and yields
    predictions regarding the formation and the overlap of memory engrams.@eng
