Bistable switching between downstates and upstates occurs robustly in the rewired ring-lattice network.

<p>This figure shows histograms of the lengths and geometric means of upstates and downstates in the rewired ring-lattice network, with and , from a simulation of overall duration 500 seconds. A total of 411 switches from down to up and up to down were detected during this time. Plots in the left column show histograms of the durations of the up and downstates, while those in the right column show histograms of the mean LFP during each up and downstate. Given that the longest up and downstates are less than 4.5 seconds, the network clearly robustly switches between up and downstates over a long time period. The mean duration of the downstates was 0.60 seconds, and the mean duration of the upstates was 0.62 seconds, and thus the mean frequency of the bistable state is of the order of one hertz.
