In order to study the J-reflex, monosynaptic reflexes were recorded from L7 or S1 ventral root after stimulation of the posterior biceps, and semi-tendinosus nerve (PBST) from the lower limb in cats anaesthetized with Pentobarbitone sodium. Intratracheal CO2 (60 ml, 100%) depressed the monosynaptic reflexes, and the depression was comparable to the effects of right atrial phenyl diguanide injection. Bilateral vagotomy did not abolish the response showing that the afferent pathway of this depression does not travel via the vagus nerve. Thus it is concluded that CO2 cannot be used to study the J-reflex.
为了研究J反射，在用戊巴比妥钠麻醉的猫中，刺激后二头肌和半腱肌神经（PBST）后，记录L7或S1腹根的单突触反射。气管内注入二氧化碳（60毫升，100%）可抑制单突触反射，这种抑制作用与右心房注射苯基双胍的效果相当。双侧迷走神经切断术并未消除该反应，表明这种抑制的传入途径并非通过迷走神经。因此得出结论，二氧化碳不能用于研究J反射。
