Many object-related actions can be recognized both by their sound and by their vision. Here we describe a population of neurons in the ventral premotor cortex of the monkey that discharge both when the animal performs a specific action and when it hears or sees the same action performed by another individual. These 'audiovisual mirror neurons' therefore represent actions independently of whether these actions are performed, heard or seen. The magnitude of auditory and visual responses did not differ significantly in half the neurons. A neurometric analysis revealed that based on the response of these neurons, two actions could be discriminated with 97% accuracy.
许多与物体相关的动作既可以通过声音识别，也可以通过视觉识别。在这里，我们描述了猴子腹侧运动前皮层中的一群神经元，当动物执行特定动作时，以及当它听到或看到另一个个体执行相同动作时，这些神经元都会放电。因此，这些“视听镜像神经元”代表动作，而与这些动作是被执行、被听到还是被看到无关。在一半的神经元中，听觉和视觉反应的强度没有显著差异。神经测量分析表明，基于这些神经元的反应，可以以97%的准确率区分两种动作。
