N-Methyl-D-aspartate receptor blockade by MK-801 produced changes in the baroreceptor related component of pre-ganglionic sympathetic discharges in kittens. Spectral analyses carried out on sympathetic and blood pressure signals demonstrated: (a) a marked reduction in amplitude of peaks, 2-6 Hz range, in sympathetic autopower spectra and (b) a substantial decrease of coherence between sympathetic and blood pressure signals in the 2-6 Hz range.
MK-801对N-甲基-D-天冬氨酸受体的阻断作用使小猫节前交感神经放电的压力感受器相关成分发生了变化。对交感神经和血压信号进行的频谱分析表明：（a）交感神经自功率谱中2-6赫兹范围内峰值的幅度显著降低，以及（b）2-6赫兹范围内交感神经和血压信号之间的相干性大幅下降。
