Fig 11. Sequence replay dynamics and speed.

Autonomous replay of the sequences {A, D, B, E} (A) and {F, D, B, C} (B), initiated by stimulating the subpopulations “A” and “F”, respectively. Red dots and blue lines mark somatic spikes and dAP plateaus, respectively, for a fraction of neurons (30%) within each subpopulation. During learning, the inter-stimulus interval ΔT is set to 40 ms. C) Dependence of the sequence replay duration on the inter-stimulus interval ΔT during learning. Replay duration is measured as the difference between the mean firing times of the populations representing the first and last elements in a given sequence. Gray areas mark regions with low prediction performance (see Dependence of prediction performance on the sequence speed). Error bands represent the mean ± standard deviation of the prediction error across 5 different network realizations. Same network and training set as in Fig 8.
