有证据表明，小脑参与了复杂的面部表情处理网络。为了评估小脑在识别面部表情中的作用，我们在小脑和前额叶皮层上进行了经颅直流电刺激（tDCS）。在小脑tDCS之前和之后，对21名健康受试者进行面部情绪识别任务;我们还测试了受试者的视觉注意力任务和视觉模拟量表（VAS）的情绪。阳极和阴极小脑tDCS都显著增强了对负面面部表情的感觉处理（阳极tDCS，p=0.0021;阴极tDCS，p= 0.018），但保持积极情绪和中性面部表情不变（p>0.05）。右侧前额叶皮层上的tDCS使消极和积极情绪的面部表情保持不变。这些发现表明，小脑特别参与处理负面情绪的面部表情。
Some evidence suggests that the cerebellum participates in the complex network processing emotional facial expression. To evaluate the role of the cerebellum in recognizing facial expressions we delivered transcranial direct current stimulation (tDCS) over the cerebellum and prefrontal cortex. A facial emotion recognition task was administered to 21 healthy subjects before and after cerebellar tDCS; we also tested subjects with a visual attention task and a visual analogue scale (VAS) for mood. Anodal and cathodal cerebellar tDCS both significantly enhanced sensory processing in response to negative facial expressions (anodal tDCS, p=0.0021; cathodal tDCS, p= 0.018), but left positive emotion and neutral facial expressions unchanged (p>0.05). tDCS over the right prefrontal cortex left facial expressions of both negative and positive emotion unchanged. These findings suggest that the cerebellum is specifically involved in processing facial expressions of negative emotion.
