Removal of Type II–I synapses abolished network bursting. No bursting was obtained when > 15% of the Type II–I synapses were removed. (A–E) Raster plots (A, top panel), network firing rates (A, bottom panel) and bursting metrics (B–E, boxplots as in Fig. 2) for an excitatory heterogeneous network with 25% of synapses removed (A) or with 5% of synapses successively removed (B–E); all removed synapses were Type II–I.
