The aim of this study is to identify if the emotional brain activity is modified by biting. We analyzed activation of several brain regions ob human subjects by using functional magnetic resonance imaging (fMRI) under different biting pressure. The biting pressure was monitored using a flat pressure sensor attached to clear retainer and was visually feed-backed to the subjects. Biting activated the occipito-temporal visual areas, the parietal visual association areas, the primary and secondary somatosensory areas, and the primary motor area. We found that the neuronal activity of amygdala was suppressed by biting.

这项研究的目的是确定是否通过咬人来改变情绪大脑活动。我们通过在不同的咬合压力下使用功能磁共振成像（fMRI）分析了几个大脑区域OB人类受试者的激活。使用连接到清除固定器的扁平压力传感器对咬合压力进行监测，并在视觉上添加给受试者。咬咬激活了枕叶视觉区域，顶壁视觉关联区域，初级和次要体感区域以及主要运动区域。我们发现杏仁核的神经元活性被咬伤抑制了。
