这些活动都伴有心血管活动的变化。边缘前脑内很多升、降压区参与这些活动。

All these activities are accompanied with changes of cardiovascular activities, and many pressor and depressor areas in the limbic forebrain are involved in regulating these activities.

实验分别采用颈动脉窦灌流及电刺激减压神经的方法，测定在产生减压效应时，家兔部分脑区及血浆内神经降压素含量的改变。

The neurotensin immunoreactive (NTIR) in plasma and some brain areas was measured when baroreceptor was excited by depressor nerve stimulation and carotid sinus perfusion.

结果及结论：该系统能对大鼠颈动脉窦区进行均匀斜坡升压，阶梯升压降压灌流，并己用于压力感受器反射效应研究中。

Results and Conclusions: This system was able to provide ramp and stepwise up down perfusion pattern and has been used in the research of baroreflex.
