多巴胺等神经调节剂在认知障碍中发挥着核心作用。在过去的十年中，关于多巴胺功能的生物学发现已经融入了强化学习计算理论中的概念。这些更抽象的方法现在已被应用于描述我们形成价值判断和做出选择时大脑中发挥作用的生物算法。这种定量模型的应用开辟了新的领域，足以受到年轻的综合学家和理论家的攻击。
Neuromodulators such as dopamine have a central role in cognitive disorders. In the past decade, biological findings on dopamine function have been infused with concepts taken from computational theories of reinforcement learning. These more abstract approaches have now been applied to describe the biological algorithms at play in our brains when we form value judgements and make choices. The application of such quantitative models has opened up new fields, ripe for attack by young synthesizers and theoreticians.
