最近的研究表明，辅助运动区可分为参与高级加工的吻侧前运动区和参与运动执行的尾侧辅助运动区。由于外科手术对内侧额叶的损伤可能导致不同的神经功能缺失，并且对SMA的结构-功能关系存在不完全的了解，我们试图确定是否可以使用功能MRI来建立共同的功能部位。结果显示，在同时完成运动和语言任务的情况下，这两个区域之间有一个共同的激活区域。与使用单独任务的人相比，测量到的信号变化百分比更高。结果有助于对SMA的结构和功能的了解，并可能区分永久性和一过性SMA综合征。
Recent research showed that the supplementary motor area (SMA) can be divided into a rostral pre-SMA, involved in higher-level processing and a caudal SMA proper, involved with motor execution. As surgical insults to the medial frontal lobes may cause variable neurological deficits and an incomplete understanding of structure–function relationships of the SMA exists, we sought to determine whether a common locus of functionality can be established using functional MRI. Results reveal a commonly activated region between these two areas, using simultaneous motor and language tasks. A higher percentage signal change was measured in comparison with those found using individual tasks. Results contribute to the structural and functional knowledge of the SMA and may enable distinction between permanent and transient SMA syndromes.
