The effective stimulating sites were indentified by defensive cardiovascular response and other components of defence reaction evoked by 3 s trains of rectangular cathodal pulses (100Hz, 0.5ms pulse duration, 70 -150μA intensity for dPAG and 150-250μA for PF) delivered from a programmed multichannel constant current stimulator. The responses included an increase in blood pressure and heart rate, pupillodilation and an increase in the rate and depth of respiration. Currents of 1Hz, intensity of 100- 150μA for dPAG and 200-250μA for PF were used to observe the effect of the stimulation of them on RVLM neurones. The deep peroneal nerve and superfacial deep peroneal nerve were carefully separated, and put on a pair of stimulating electrode respectively, Both nerves were stimulated with constant rectangular pulses of 1Hz, 0.5ms duration and 300μA current intensity to see their effects on RVLM neurones. The baro-and chemo-receptors were activated by the intravenous injection of phenylephrine or 0.208 M NaH2PO4. The degree of convergent inputs to individual RVLM neurone was studied by the stimulation of the sites mentioned above. It was found that neurones about 61.4%(27/44) and 35.3%(6/17) received convergent inputs from three and four places respectively.
过去的研究主要集中于整体水平,利用电刺激或化学刺激RVLM神经元,观察对血压、心率及交感活动的影响,并对影响心血管交感活动的神经递质进行了广泛探讨,积累了大量资料;在神经元水平,主要研究刺激脑内核团、外周神经、化学感受器及压力感受器等对RVLM神经元放电的影响和某些神经递质影响神经元活动的机制、然而,对RVLM神经元如何整合不同信息、其可能突触机制等研究得较少,本互作拟采用在体细胞内、细胞外记录电活动与微电泳,结合中枢核团及外周神经电刺激等方法,对RVLM神经元在不同状态下的整合作用规律与可能机制进行初步探讨,为进一步了解这一复杂的整合过程提供新的理论依据。
