本文提出了一个新的假设，边缘系统可能有助于运动学习。边缘系统和感觉运动相关系统的相互作用是学习在运动任务中做什么（适当的，相关的行为）以及如何做得最好（运动技能）的必要条件。边缘调制的感觉运动相关的神经中心的设想，导致在不同的神经中心的收敛输入相关敏感的杏仁核和推论，皮质调制的收件人杏仁核信息的比较。这种相对的“原始”边缘系统输入和它们的“加工”的推论形式的比较可以通过类似于小脑的侧环方式来实现。这种“边缘系统比较器”假说是由运动学习的研究提出的，这些研究表明，猴子只有在洞察到适当的、与任务相关的行为之后才能发展技能，而在过渡到洞察状态的过程中，不适当的行为会产生来自前扣带皮层的“错误”信号。已知的边缘系统的预测，可以服务于推论比较的网站进行检查方面的动机，适当的，任务相关的行为和运动技能的可能影响。在感觉运动相关的神经中枢的收敛和比较的解剖和功能测试的建议，以刺激调查的边缘比较假说。
This paper offers a new hypothesis about how the limbic system might assist motor learning. It is proposed that interactions of limbic and sensorimotor-related systems are essential learning what to do in a motor task (appropriate, relevant behavior) and how to do it best (motor skill). Limbic modulations of sensorimotor-related neural centers are envisaged to result from comparisons in various neural centers of converging inputs from the relevance-sensitive amygdala and from corollary, cortically-modulated recipients of amygdaloid information. Such comparisons of relative ''raw'' limbic inputs and their ''processed'', corollary forms could be achieved in a side-loop manner resembling that in the cerebellum. This ''limbic comparator'' hypothesis was prompted by studies of motor learning that show how monkeys develop skill only after gaining insight into appropriate, task-related behavior, and that inappropriate behavior during transition into the insightful state produces ''error'' signals from the anterior cingulate cortex. Known sites of limbic projections that could serve corollary comparisons are examined with regard to their possible influence on motivation, appropriate, task-related behavior and motor skill. Anatomical and functional tests of convergence and comparison in sensorimotor-related neural centers are suggested in order to stimulate investigations of the limbic comparator hypothesis.
