Figure 3: Representative network simulations (I)–(IX): raster plot sections (top) with corresponding firing rates (middle, last 1.5 s of simulation time), and ISI probability density distributions (bottom, semilogarithmic plots with a zoom-in with linear axes). In the raster plots, gray dots represent inh. spikes, and black dots represent exc. spike times while the other two plots do not distinguish between exc. and inh. neurons. The plots are ordered and numbered according to their occurrence in the phase space: On the top left synchronous regular firing dominates due to low inhibition (small g) and high input rates. On the bottom right, there is asynchronous irregular firing due to a higher inhibition (large g) and lower input rates.
