The neostriatum has a mosaic organization consisting of striosome and matrix compartments. It receives glutamatergic excitatory afferents from the cerebral cortex and thalamus. Recent behavioral studies in rats revealed a selectively active medial prefronto-striosomal circuit during cost-benefit decision-making. However, clarifying the input/output organization of striatal compartments has been difficult because of its complex structure. We recently demonstrated that the source of thalamostriatal projections are highly organized in striatal compartments. This finding indicated that the functional properties of striatal compartments are influenced by their cortical and thalamic afferents, presumably with different time latencies. In addition, these afferents likely support the unique dynamics of striosome and matrix compartments. In this manuscript, we review the anatomy of basal ganglia networks with regard to striosome/matrix structure. We place specific focus on thalamostriatal projections at the population and single neuron level.

丘脑上的突起和基质体基质区室。

新纹状体具有由核小体和基质区室组成的镶嵌组织。它从大脑皮层和丘脑接受谷氨酸能兴奋性传入。最近对大鼠进行的行为研究表明，在进行成本效益决策时，有选择性地激活了前额叶-纹状体内侧回路。但是，由于其复杂的结构，很难明确纹状体隔室的输入/输出组织。我们最近证明，在纹状体隔室中，丘脑垂体投射的来源高度组织。这一发现表明，纹状体隔室的功能特性受其皮质和丘脑传入传入的影响，可能具有不同的时间延迟。另外，这些传入分子可能支持核糖体和基质区室的独特动力学。在这份手稿中 我们回顾了关于纹状体/基质结构的基底神经节网络的解剖结构。我们特别关注人群和单个神经元水平的丘脑预测。
