    "title": "Lateral Inhibition Overcomes Limits of Temporal Difference Learning",
    "subtitle": null,
    "abstract": "There is growing support for Temporal Difference (TD) Learning\nas a formal account of the role of the midbrain dopamine\nsystem and the basal ganglia in learning from reinforcement.\nThis account is challenged, however, by the fact that realistic\nimplementations of TD Learning have been shown to fail on\nsome fairly simple learning tasks — tasks well within the capabilities\nof humans and non-human animals. We hypothesize\nthat such failures do not arise from natural learning systems\nbecause of the ubiquitous appearance of lateral inhibition in\nthe cortex, producing sparse conjunctive internal representations\nthat support the learning of predictions of future reward.\nWe provide support for this conjecture through computational\nsimulations that compare TD Learning systems with and without\nlateral inhibition, demonstrating the benefits of sparse conjunctive\ncodes for reinforcement learning.",
