In vivo and in vitro avalanche-size distributions <i>p</i>(<i>S</i>) from LFP depend on time-bin size Δ<i>t</i>.

Experimental LFP results are reproduced by many dynamics states of coarse-sampled simulations. A: Experimental in vivo results (LFP, human) from an array of 60 electrodes, adapted from [43]. B: Experimental in vitro results (LFP, culture) from an array with 60 electrodes, adapted from [1]. C–F: Simulation results from an array of 64 virtual electrodes and varying dynamic states, with time-bin sizes between 2 ms ≤ Δt ≤ 16 ms, γ = 1 and dE = 400 μm. Subcritical, reverberating and critical dynamics produce approximate power-law distributions with bin-size-dependent exponents α. Insets: Log-Log plot, distributions are fitted to p(S) ∼ S−α, fit range S ≤ 50. The magnitude of α decreases as Δt−β with −β indicated next to the insets, cf. Table 2.
