心率变异性(HRV)分析是非侵入性评估自主神经功能的常用方法 .在许多研究中,低频变异性(LF,如通过快速傅立叶变换产生的功率谱中所示的0.15 Hz)作为副交感神经功能的指标.通过对15位心-身锻练习练者和20位非习练者的对照研究,我们发现以下是影响HRV的重要因素.第一,呼吸周期的频率反映在由呼吸性窦性心律不齐(RS A)产生的功率谱中的峰值频率中.在涉及年轻受试者的情况下,即使以单一速率严格控制他们的呼吸,也能在功率谱中看到多个峰;第二,由RSA产生的HRV峰的大小取决于每次呼吸的潮气量和受试者的姿势;第三,在相同条件下,与年龄较大的受试者(年龄在50~70岁)相比,年轻受试者(年龄在20~25岁)通常显示更大的RSA峰值.这种效应常常掩盖了基于其他因素的差异,例如多年的心-身锻练.总之,这项研究表明了HRV分析用于评估自主神经功能的心-身研究可以作为一个有用的工具,但需注意必须采取措施控制所有上述因素.

The globus pallidus plays a pivotal role in the basal ganglia circuit. Parkinson's disease is characterized by degeneration of dopamine-producing cells in the substantia nigra, which leads to dopamine deficiency in the brain that subsequently manifests as various motor and non-motor symptoms. This review aims to summarize the involvement of the globus pallidus in both motor and non-motor manifestations of Parkinson's disease. The firing activities of parvalbumin neurons in the medial globus pallidus, including both the firing rate and pattern, exhibit strong correlations with the bradykinesia and rigidity associated with Parkinson's disease. Increased beta oscillations, which are highly correlated with bradykinesia and rigidity, are regulated by the lateral globus pallidus. Furthermore,bradykinesia and rigidity are strongly linked to the loss of dopaminergic projections within the cortical-basal ganglia-thalamocortical loop. Resting tremors are attributed to the transmission of pathological signals from the basal ganglia through the motor cortex to the cerebellum-ventral intermediate nucleus circuit. The cortico–striato–pallidal loop is responsible for mediating pallidi-associated sleep disorders. Medication and deep brain stimulation are the primary therapeutic strategies addressing the globus pallidus in Parkinson's disease. Medication is the primary treatment for motor symptoms in the early stages of Parkinson's disease, while deep brain stimulation has been clinically proven to be effective in alleviating symptoms in patients with advanced Parkinson's disease,particularly for the movement disorders caused by levodopa. Deep brain stimulation targeting the globus pallidus internus can improve motor function in patients with tremordominant and non-tremor-dominant Parkinson's disease, while deep brain stimulation targeting the globus pallidus externus can alter the temporal pattern of neural activity throughout the basal ganglia–thalamus network. Therefore, the comp
