基底神经节在认知中起着核心作用，并参与动作选择和强化学习等一般功能。在这里，我们提出了一个模型，探索假设基底神经节实现条件信息路由系统。该系统通过分别操纵信息传输的源和目的地的选择来指导皮层信号在成对区域之间的传输。我们认为，这种机制提供了一个帐户的几个认知功能的基底神经节。该模型还包含了一种可能的机制，通过这种机制，随后的信息传输控制多巴胺的释放。这个信号被用来产生新的刺激-反应协会通过内化转移皮层代表在纹状体。我们讨论该模型如何与生产系统和认知架构相关。一系列的模拟，以说明该模型可以执行简单的刺激反应任务，开发自动行为，并提供一个帐户的帕金森氏症和亨廷顿氏病的损害。
The basal ganglia play a central role in cognition and are involved in such general functions as action selection and reinforcement learning. Here, we present a model exploring the hypothesis that the basal ganglia implement a conditional information-routing system. The system directs the transmission of cortical signals between pairs of regions by manipulating separately the selection of sources and destinations of information transfers. We suggest that such a mechanism provides an account for several cognitive functions of the basal ganglia. The model also incorporates a possible mechanism by which subsequent transfers of information control the release of dopamine. This signal is used to produce novel stimulus–response associations by internalizing transferred cortical representations in the striatum. We discuss how the model is related to production systems and cognitive architectures. A series of simulations is presented to illustrate how the model can perform simple stimulus–response tasks, develop automatic behaviors, and provide an account of impairments in Parkinson’s and Huntington’s diseases.
