正电子发射断层扫描（PET）被用来识别在句子的“内部手势”过程中激活的大脑区域，这些受试者是深度耳聋，通常使用手语进行交流。虽然这似乎涉及手和手臂在空间中运动的内部表征，但它激活了左下额叶皮层，而不是视觉空间区域。被激活的区域对应于听力受试者在句子的无声发音过程中所参与的区域。这表明，“内部手语”是由类似的区域内部语言，是一致的神经心理学数据暗示在手语的产生左半球。
POSITRON emission tomography (PET) was used to identify the brain regions activated during the 'inner signing' of sentences in subjects who were profoundly deaf and normally communicated using sign language. Although this appeared to involve the internal representation of hand and arm movements in space, it activated the left inferior frontal cortex rather than visuo-spatial areas. The activated region corresponds to that engaged during the silent articulation of sentences in hearing subjects. This suggests that 'inner signing' is mediated by similar regions to inner speech, and is consistent with neuropsychological data implicating the left hemisphere in the generation of sign language.
