. We investigate the three-dimensional dynamical system occurring in the network regulatory systems theory for specific choices of regulatory matrix {{0, 1, 1}{1, 0, 1}{1, 1, 0}} and sigmoidal regulatory function f(z) = 1/(1 + e−μz), where z = ∑ Wijxj − θ. The description of attracting sets is provided. The attracting sets consist of respectively one, two or three critical points. This depends on whether the parameters (μ, θ) belong to a setΩ or to the complement ofΩ or to the boundary of Ω, where Ω is fully defined set.
