The article Principles for consciousness in integrated cognitive control by Ricardo Sanz, Ignacio López, Manuel Rodríguez and Carlos Hernández has been published in the journal Neural Networks

In this paper we will argue that given certain conditions for the evolution of biological controllers, they will necessarily evolve in the direction of incorporating consciousness capabilities. We will also see what are the necessary mechanics for the provision of these capabilities and extrapolate this vision to the world of artificial systems.
