The ineligible role of the caudate nucleus in sleep has been implicated. Previous literature showed that the caudate volume is associated with longer habitual sleep duration in older adults. However, the association between sleep duration and caudate volume remains unknown in the younger population. In this study, we examined the caudate volume in youth to older adults (10 to 85 years old) with a greater sample size (N = 464). The volumetric size of the caudate nucleus showed significantly positive association with habitual sleep duration, especially in younger population. Sleep duration showed a significant association with executive function performance. However, caudate volume did not significantly predict executive function. Our results suggested that sleep duration is associated with the caudate volume and executive function. It is also suggested that there are some external mechanisms that modulate executive function which prevent the caudate-sleep relation's effect on executive function.
尾状核在睡眠中不合适的作用已被提及。先前的文献表明，尾状核体积与老年人较长的习惯性睡眠时间有关。然而，在较年轻人群中，睡眠时间与尾状核体积之间的关联仍不明确。在本研究中，我们以更大的样本量（N = 464）对10至85岁的青年至老年人的尾状核体积进行了检查。尾状核的体积大小与习惯性睡眠时间呈显著正相关，尤其是在较年轻人群中。睡眠时间与执行功能表现呈显著相关。然而，尾状核体积并未显著预测执行功能。我们的结果表明，睡眠时间与尾状核体积及执行功能有关。还表明存在一些调节执行功能的外部机制，这些机制阻止了尾状核 - 睡眠关系对执行功能的影响。
