Others have reported that spinal cord transection non-uniformly affects the activities of the cardiac, renal and splenic nerves. We were unable to confirm this finding while recording the wide band (1-1000 Hz) discharges of these sympathetic nerves in baroreceptor-denervated, chloralose-anesthetized cats. Most of the power in nerve discharges was below 6 Hz. There was high coherence between the low frequency discharges of different nerves, and power below 15 Hz was essentially eliminated by spinal transection. Evidence is presented that the disparities between this and past studies are, in part, due to the use of a 30-Hz high-pass filter in the earlier studies.
其他人报告称，脊髓横断对心脏、肾脏和脾脏神经活动的影响并不均匀。在记录压力感受器去神经支配、水合氯醛麻醉猫的这些交感神经宽带（1-1000赫兹）放电时，我们无法证实这一发现。神经放电的大部分能量低于6赫兹。不同神经的低频放电之间具有高度相关性，脊髓横断基本消除了15赫兹以下的能量。有证据表明，本研究与以往研究之间的差异部分归因于早期研究中使用了30赫兹的高通滤波器。
