Dynamical properties of the circuits without plasticity. (a, b) Raster plot of the spiking time of 200 stimulated neurons (extra stimulation onset at for . (a) Highly synchronous state with . (b) Asynchronous state, (c–e) Circuit properties with respect to synaptic strength during extra stimulus. The cases of different values are plotted in different colors, and the values corresponding to different colors are shown in the bar. (c) Network firing rate. (d) Synchrony index. (e) Gamma power.
