Cognition, Action Selection, and Inner Rehearsal

Murray Shanahan


This paper presents a large-scale model of the ar-chitecture of the mammalian brain, the core circuit of which carries out inner rehearsal of interaction with the environment to realise a form of cognitively mediated action selection. As it alternates between broadcast to and competition between its component neural assemblies, the core circuit ex-hibits an episodic dynamics suggestive of cortical processing in discrete frames. The implemented ar-chitecture is used to control a simulated robot, and a classic experimental paradigm in which rats per-formed apparently goal-directed action selection is emulated.
