Top: Average k of all neurons ignited at each time step t from one particular realization of the simulation. Bottom: Times of ignition for all 500,000 individual neurons. It is evident that highly connected neurons are the first-to-fire. For clarity we plot time only from t = 1 and do not show the  ∼ 1,000 neurons that were initially ignited at t = 0. We used here f = 0.0033 and p_k which for k < k_tail is a Gaussian centered on $k=75$ with width σ = 31 and is a power law p_k ∼ k⁻² for k > k_tail. We checked that a simple Gaussian p_k gives the same qualitative results.
