Impact of learning during rest/sleep with SPW/R-like replay events. The feedforward substructure is first learned in an exploration phase (for 5, 10, and 15 runs along the tracks in A–C, respectively; the network is the same as in Fig. 10). The networks continue to learn in the subsequent simulated rest/sleep phase, where SPW/R-like events are initiated by stimulating a random subset of g₀ = 50 excitatory neurons every 400 ms. Different colors show the mean connection strength as a function of the distance between the place-field centers of the postsynaptic and the presynaptic neuron after 0, 500, 1000, and 4000 events. The feedforward structure is attenuated.
