The cortical activity was investigated using spectral analysis of electroencephalogram (EEG) to clarify the cortical activation accompanying mastication, swallowing, and motor imagery of mastication and swallowing. The EEG was recorded using a 19-channel EEG system (SYNAFIT 2500, NEC Co).1. Cortical activation accompanying mastication : brain activation by mastication could be expressed as the relaxed wakefulness with some intense mental activity from the topographical aspects of EEG spectrum, also food intake could be related to the mental intense for the preparation of masticatory performance.2. Cortical activation accompanying masticatory duration : brain activation could be affected by the duration of mastication based on the topographical aspects of EEG spectra, such as the appearance of theta and/or delta waves.3. Cortical activation accompanying food hardness on mastication : cortical activation could be affected by food textures such as hardness, which is expressed by the appea … More rances of alpha and beta waves and disappearance of theta and/or delta wave.4. Cortical activation accompanying masticatory imagery : brain activation shown by masticatory imagery could be described as typical relaxed wakefulness without intense mental activity in the frontal cortex area based on EEG spectra.5. Cortical activation accompanying swallowing : in comparing spectral wave factors of EEG between pre- and post- swallowing, the beta 1, the beta 2, and delta waves were significantly increased in the post-swallowing phase. Therefore, it is assumed that cortical activation by swallowing could be described as intense mental activity based on the topographical aspects of EEG spectra.6. Cortical activation accompanying swallowing imagery : brain activation in accordance with swallowing imagery could be described as typical of relaxed wakefulness without intense mental activity based on the topographical aspects of EEG spectra.7. The effect of mastication to cortical activation in TMDs : TMDs lack the cortical activation shown by the increases in alpha and beta wave factors and decrease in theta wave factor which presented in the frontal area of normal subjects. This may be related to modification of masticatory motor behaviors.From the above results, it is concluded that EEG spectra could be indicated peculiar topographical findings according to the aspects of mastication, swallowing and motor imagery of mastication and swallowing, and further modification of EEG spectra could be indicated in TMDs.

使用脑电图（EEG）的光谱分析研究了皮质活性，以阐明皮质激活涉及咀嚼，吞咽和咀嚼和吞咽的运动成像。使用19通道EEG系统（SYNAFIT 2500，NEC CO）记录EEG。1。皮质激活参与咀嚼：通过咀嚼的大脑激活可以表示为放松的觉醒，从脑电图的地形方面进行了一些激烈的心理活动，而食物摄入也可能与制备咀嚼性能的精神强度有关。2。皮质激活涉及咀嚼持续时间：基于EEG光谱的地形方面（例如Theta和/或Delta Waves的出现），大脑激活可能会受到咀嚼持续时间的影响。3。皮质激活参与咀嚼的食物硬度：皮质激活可能会受到诸如硬度之类的食物质地的影响，这些食物是由外观表达的……alpha和β波的更多rances rance and theta和theta和/或Delta Wave的消失。4。皮质激活涉及咀嚼图像：咀嚼图像所示的大脑激活可以描述为典型的松弛觉醒，而基于脑电图光谱5。皮质激活涉及吞咽：在比较吞咽前和吞咽后的EEG的光谱波因子时，β1，β2和三角波在碎片后阶段显着增加。因此，假定吞咽的皮质激活可以被描述为基于脑电图的地形方面的激烈的心理活动。6。皮质激活涉及吞咽图像：根据吞咽图像的大脑激活可以描述为典型的放松觉醒，而无需基于EEG光谱的地形方面强烈的心理活动。7。 TMDS中咀嚼对皮质激活的影响缺乏由α和β波因子的增加所示的皮质激活以及在正常受试者额叶区域中呈现的Theta波因子的降低。这可能与咀嚼运动行为的修饰有关。从上述结果，可以得出结论，可以根据咀嚼，咀嚼和吞咽的吞咽和运动成像的各个方面表明脑电图的特殊形式发现，并且可以在TMD中进行进一步的EEG光谱。较少的
