摘要

观察了RVLM区神经元电活动对电刺激中脑防御反应区的诱发反应,以及对压力感受性反射的反应。并用FFT对RVLM区神经元自发单位放电和血压波进行频域的相干性分析,以判断是否具有心节律。还分析了RVLM区单位放电变异性与心率变异性的相干性。

Abstract

The analyze the coherence between neuronal discharges (ND) in the rostral ventrolateral medulla (RVLM) and the cardiovascular activity, we observed the neuronal discharge in RVLM responding to electric stimulation of the defense area of the midbrain. Fast Fourier transform (FFT) was performed to analyze the coherence between the signals of ND and blood pressure to determine if the ND were cardiac rhythmic. The coherence between ND variability (NDV) and heart rate variability (HRV) was also analyzed.

Key words: Neuronal activity;Arterial blood pressure;Rostral ventrolateral medulla;Heart rate variability;Coherence analysis
