最近的研究假设辅助运动区在运动抑制中起作用。为了研究这种可能的作用，我们使用功能性MRI研究来比较需要不同水平的运动模式抑制的条件。17名健康参与者在执行时进行扫描-主动或被动-右手有节奏的打开/关闭动作，有和没有一致的视觉信息。在视觉引导条件下的对比被动>主动运动，其需要抑制以便“不”执行运动，产生通常涉及抑制性脑回路的区域的显著激活，其中，值得注意的是，控制侧辅助运动区。NeuroReport 20：1351-1355（C）2009 Wolters Kluwer Health竖条Lippincott威廉姆斯& Wilkins.
Recent studies have hypothesized that the supplementary motor area plays a role in motor inhibition. To study this possible role, we used functional MRI study to compare conditions, which require various level of inhibition of motor patterns. Seventeen healthy participants were scanned while executing - actively or passively - rhythmic opening/closing movements of their right hand, with and without congruent visual information. The contrast passive>active movement in the visual guidance condition which requires inhibition in order 'not' to perform the movement, yields to significant activation of areas commonly involved in the inhibitory brain circuitry among which, notably, controlateral supplementary motor area.
