目前关于人类镜像神经元的存在有很多争论。为了识别人类额下回（IFG）中的镜像神经元，我们采用了重复抑制范式，同时使用功能磁共振成像测量神经活动。受试者执行或观察一系列动作。这里我们表明，在IFG中，当执行的动作之后是相同而不是不同的观察到的动作，以及当观察到的动作之后是相同而不是不同的执行动作时，反应都会被抑制。这种反应模式与镜像神经元预测的一致，是人类IFG中镜像神经元存在的证据。
There is much current debate about the existence of mirror neurons in humans. To identify mirror neurons in the inferior frontal gyrus (IFG) of humans we employed a repetition suppression paradigm while measuring neural activity with functional magnetic resonance imaging. Subjects either executed or observed a series of actions. Here we show that in the IFG, responses were suppressed both when an executed action was followed by the same rather than a different observed action and when an observed action was followed by the same rather than a different executed action. This pattern of responses is consistent with that predicted by mirror neurons and is evidence of mirror neurons in the human IFG.
