在过去的十年里，我们对纹状体在行为中的作用的理解发生了巨大的变化。早期的观点强调纹状体在刺激-反应关联和动作序列的习惯性学习中的作用。人类神经影像学研究的最新进展表明纹状体在动机学习中具有更广泛的作用。新的研究结果表明，纹状体代表了多种学习信号，并强调了纹状体在许多认知领域和环境中的贡献。最近的发现也强调纹状体和其他专门的大脑学习系统之间的相互作用。总之，这些发现表明纹状体有助于一个分布式网络，该网络学习根据预测值选择行动，以优化行为。
The past decade has seen a dramatic change in our understanding of the role of the striatum in behavior. Early perspectives emphasized a role for the striatum in habitual learning of stimulus–response associations and sequences of actions. Recent advances from human neuroimaging research suggest a broader role for the striatum in motivated learning. New findings demonstrate that the striatum represents multiple learning signals and highlight the contribution of the striatum across many cognitive domains and contexts. Recent findings also emphasize interactions between the striatum and other specialized brain systems for learning. Together, these findings suggest that the striatum contributes to a distributed network that learns to select actions based on their predicted value in order to optimize behavior.
