We analyze the effect of such a regulation on the dynamics of a network with excitatory and inhibitory neurons and uniform connectivity within and across the two populations. We show that, under broad conditions, the system converges to a critical state lying at the common boundary of three regions in parameter space; these correspond to three modes of behavior: high activity, low activity, oscillation.35 pages, 8 figuresNeural and Evolutionary ComputingArtificial IntelligenceAdaptation and Self-Organizing SystemsQuantitative BiologyI.2.6text
