Effect of High-Frequency Stimulation in the Pedunculopontine Nucleus on Neuronal Activity and Neurotransmitters in the Globus Pallidus Internus of Rats
Objective To study the effect of high frequency stimulation (HFS) in pedunculopontine nucleus (PPN) on the neuronal activities of globus pallidus internus (Gpi) in Parkinson ’ s disease (PD) model rats, and the mechanisms there of. Methods Seventy male Sprague-Dawley rats were divided into two groups, control group ( n =30) and PD model group ( n = 40). PD rat model was established by the injection of 6-OHDA into substantia nigra pars compacta (SNc) on the right side of the brain with stereotactic technique...

帕金森病(PD)是以中脑黑质多巴胺能神经元变性缺失为主要病理变化的渐进性神经系统退行性疾病。高频电刺激(high frequency stimulation,HFS)丘脑底核(subthalamic nucleus,STN)、苍白球内侧部(GPi)等基底神经节核团是功能外科治疗PD的首选方法[1],但是该方法对步态障碍、静止?
