Activity driven sleep dynamics: A conceptual modeling study
Fig 5
Averaged activity of an ensemble.
An ensemble include of 100 sleep units as a function of the parameters knet and PSDinputs, which specify the strength of excitatory connections within the ensemble and the percentage of units receiving an external PSD signal, respectively. (A) Sketch of the diagram showing the regions of the main modes. (B) and (C) The change of mode along the dashed lines B and C in panel A, respectively. (D) A similar signal obtained by replacing the ensemble with a single sleep unit equipped with positive feedback. For further details see the text.
