Probability tree of all possible transitions in a network of size $N=3$. Simulations start from a state with no active neurons: $N_0=0$. The diagram shows the possible transitions at each step, along with the probability of making that transition. The probabilities are as defined in the main text with $q_i$ being the probability of a neuron switching from the active to the quiescent state given i initially active neurons. Dotted lines indicate transitions that are already shown elsewhere in the tree and so the tree shown here completely describes all possible transitions in a network of this size
