这项研究的目的是确定咬人是否会改变大脑的情绪活动。我们利用功能磁共振成像(FMRI)分析了不同咬合压力下受试者几个脑区的激活情况。咬合压力通过连接到清洁固位体上的平面压力传感器进行监测,并通过视觉反馈给受试者。咬人激活了枕颞区、顶叶视觉联想区、初级和次级躯体感觉区以及初级运动区。我们发现,咬伤会抑制杏仁核的神经元活动。
英文摘要
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.
