对50例正常老年人的前额叶皮层与小脑-小脑功能的关系进行了研究。通过字母流畅性测试和数字取消测试（D-CAT，一种用于评估注意力的测试）来测量前额叶皮层的功能。两个指标的姿势震颤所测量的稳定器被用来指示小脑-丘脑-皮质回路功能。由稳定指数测量结果高于或低于正常平均值的参与者组成的组的结果与他们的D-CAT和字母流畅性测试表现进行了比较。结果表明，小脑-丘脑-皮层回路功能的2项指标与注意功能有关，而与语言功能的相关性较弱，行为测量结果表明，前额叶皮层和小脑-丘脑-皮层回路功能之间存在相互联系，并有力地支持了人脑是一个包括新皮层、皮层下和小脑的系统的观点。
The relation between prefrontal cortex and cerebro-cerebellar functions of 50 normal healthy elderly people was examined. The function of the prefrontal cortex was measured by means of a letter fluency test and the Digit Cancellation Test (D-CAT, a test for the assessment of attention). Two indexes of postural tremor measured by the stabilometer were employed for the indication of cerebello-thalamo-cortical circuit functions. The results of groups consisting of participants showing higher or lower scores than the mean of the norm on the stabilometer index measurements were compared with their D-CAT and letter fluency test performances. The results showed that 2 indexes of cerebello-thalamo-cortical circuit functions related to the attention function while the relation to the language function was rather weak.The results of the behavioral measures demonstrated a mutual relation between prefrontal cortex and cerebello-thalamo-cortical circuit functions and strongly suggest the notion that the human brain functions as a system, which includes neocortex, subcortex, and cerebellum.
