Information filtering by coincidence detection of synchronous population output: analytical approaches to the coherence function of a two-stage neural system.

abstract：:It has been suggested that the mammalian memory system has both familiarity and recollection components. Recently, a high-capacity network to store familiarity has been proposed. Here we derive analytically the optimal learning rule for such a familiarity memory using a signal- to-noise ratio analysis. We find that in...
