1. Any food or drink containing theobromine is forbidden. Chocolate, cocoa, coffee, and tea contain theobromine, which can cause over excitability, cardiopathy, and death. 任何含有可可碱的食物或饮料都是被禁止的，巧克力、咖啡和茶都含有可可碱，这些能引起过度兴奋、心脏病和死亡。
2. Furthermore, the effects of Rhein on the neural excitability transmission were analyzed, which showed that the wavelet entropy of EPSP was significantly decreased by Rhein. 进而分析了大黄酸对中枢兴奋性传递的作用，发现神经元在灌流大黄酸前后小波熵参数数值变化显著。
3. It has been found that NaSal significantly suppresses the functional activity of GABA neurons, suggesting that NalSal raises excitability in the central auditory system to induce tinnitus. 我们发现该药物显著地压制GABA神经元的自发活动水平，提示水杨酸钠通过提高中枢听觉系统的兴奋性诱导耳鸣。
