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.
最近的研究推测，辅助运动区在运动抑制中发挥作用。为了研究这一可能的作用，我们使用功能磁共振成像研究来比较需要对运动模式进行不同程度抑制的条件。17名健康参与者在执行右手有节奏的开合运动时（主动或被动），在有和没有一致视觉信息的情况下接受扫描。在视觉引导条件下，被动>主动运动这种需要抑制以便“不”执行运动的对比，导致通常参与抑制性脑回路的区域显著激活，其中特别值得注意的是对侧辅助运动区。
