Previous studies of PD patients and animal model indicate that neurotransmitters and receptors are changed in globus pallidus neurons,the balance between inhibition and excitation is broken in the output nuclei of basal ganglia,and globus pallidus neurons display bursting and oscillatory discharge,the synchronous tendency of neighboring neurons enhances. These neurophysiological changes are associated with PD symptoms,such as bradykinesia,rigidity and tremor,which reflects that globus pallidus plays an important role in the process of PD.
