Fig. 5.

Simulated activity during postrefinement sleep. A: 10 s of EEG, showing smaller slow waves. B: mean synaptic currents of the populations in the supragranular layer with different POs, plotted individually. Populations are much less synchronous in their activity, as well as more variable in the timing of their UP states, than in the prerefinement model (compare with Fig. 3B). C: mean membrane potential of the thalamic matrix cells. D: snapshots of the supragranular membrane potential of 20 × 20 populations over 1 s, with an image captured every 50 ms from the 4 populations with different POs. E: postrefinement model shows a decrease in SWA. F: the lower frequency power spectrum of the pre- and postrefinement conditions averaged across sleep epochs. G and H: amplitude (G) and slope (H) of the slow waves have decreased postrefinement. Error bars denote SE.
