    • Conditions favoring independence are sparse connectivity, a random distribution of synaptic efficacies which can compensate for sparsness when connectivity is high or, in general, a suitable source of quenched randomness affecting the communication among the neurons

    • We remark that in deriving the above Fokker-Planck equation in the general case (2.2) of a multiplicative noise, the condition (Formula presented) plays a crucial role, since if the latter condition is not fulfilled, a further, “noise-induced” drift appears in the A coefficient of the Fokker-Planck equation

    • While the stability condition (Formula presented) appears superficially consistent with general and standard arguments, it applies to a special case (see below for other examples). Besides, we argue in Sec. IV that simple arguments appropriate for a first-order dynamics lead to wrong conclusions in the case under study

    • A pole near one of the eigenvalues of L, driving the instability of the network for small (Formula presented) (which our analysis proves to be a special, large (Formula presented) effect) had been predicted in Ref. 22 to be a general property, on the basis of what appears as an unwarranted condition imposed on the poles near (Formula presented)

    • We mention for completeness that in the small-(Formula presented) limit, in the drift-dominated regime the eigenvalues (therefore, in most conditions, the diffusion poles) have a real part (Formula presented) such that as (Formula presented) the diffusion poles bring about a marginal stability. See also 6 and 22 for a discussion of the eigenvalues of L in the limit of small (Formula presented)

    • For example, for the extreme case of full connectivity, with all synapses chosen as random variables drawn from the same probability distribution, the afferent currents to two generic neurons are determined by the convolution of the same realization of a stochastic point process (the common sequence of afferent spikes) with two independent realizations of the process generating the synaptic couplings
