abstract = {It is frequently hypothesized that cortical networks
operate close to a critical point. Advantages of criticality
include rich dynamics well-suited for computation and
critical slowing down, which may offer a mechanism for
dynamic memory. However, mean-field approximations, while
versatile and popular, inherently neglect the fluctuations
responsible for such critical dynamics. Thus, a renormalized
theory is necessary. We consider the
Sompolinsky-Crisanti-Sommers model which displays a well
studied chaotic as well as a magnetic transition. Based on
the analogue of a quantum effective action, we derive
self-consistency equations for the first two renormalized
Greens functions. Their self-consistent solution reveals a
coupling between the population level activity and single
neuron heterogeneity. The quantitative theory explains the
population autocorrelation function, the single-unit
autocorrelation function with its multiple temporal scales,
and cross correlations.},
