A connectionist model of cortico-striato-thalamic loops unifying ring learning and action selection is proposed. The aim in proposing the connectionist model is to develop a simple model revealing the mechanisms behind the cognitive process of goal directed behaviour rather than merely obtaining a model of neural Structures. In the proposed connectionist model, the action selection is realized by a non-linear dynamical system, while learning that modifies the action selection is realized similar to actor-critic model of reinforcement learning. The task of sequence learning is solved with the proposed model to make clear how the model can be implemented.
