用玻璃微电极记录下丘脑后核（ＰＨＮ）内神经元单位放电，大豆皂甙（Ｔｓ）注入侧脑室引起与血压反应有关神经元放电频率增加，减压反射时ＰＨＮ内放电减少的有关神经元放电增加，这可能是Ｔｓ引起升压反应的原因，因为ＰＨＮ兴奋可以引起血压升高。
The use of glass microelectrodes to record the unit discharge of neurons in the hypothalamic nuclei (PHN) and the infusion of soy saponin (Ts) into the lateral ventricle caused an increase in the firing frequency of neurons associated with the blood pressure response and a decrease in the discharge of neurons in the PHN during decompression reflexes Increased, this may be the reason that Ts caused a boosting response, because PHN stimulation can cause blood pressure to rise.
