Fig 5. Modulation of damping rate of δ–activity subjected to excitatory and inhibitory synaptic time constants.

(A) The δ–peak damping rate slightly decreases by the increase in β_e, whereas (C) it considerably decreases as β_i increases. (B, D) Damping rate of δ–activity remains constant with respect to parameters α_e and α_i. In all panels, unchanged parameters are taken from Table 1.
