In chloralose anaesthetized and paralyzed normotensive (Wistar, Wistar--Kyoto) and spontaneously hypertensive rats (SHR), a somatosympathetic reflex in the cervical sympathetic trunk elicited by a single electrical shock to forelimb afferent fibres in the median nerve was recorded. It has been shown that the elicited response of SHR is similar to the response of normotensive rats. Amplitude of somatosympathetic reflex in SHR is larger than that of somatosympathetic reflex in normotensive animals. It is supposed that somatosympathetic reflex in hypertensive and normotensive rats is formed in the same way. However, reflex excitability of sympathetic nervous system in SHR is greater.
在水合氯醛麻醉并麻痹的正常血压（Wistar、Wistar - Kyoto）和自发性高血压大鼠（SHR）中，记录了通过对正中神经的前肢传入纤维进行单次电击在颈交感干中引发的躯体交感反射。结果表明，SHR引发的反应与正常血压大鼠的反应相似。SHR中躯体交感反射的幅度大于正常血压动物中躯体交感反射的幅度。据推测，高血压大鼠和正常血压大鼠的躯体交感反射以相同方式形成。然而，SHR中交感神经系统的反射兴奋性更高。
