Early Interventions and Stereotactic Lesioning
During the 1950s and 1960s, stereotactic surgery lesioning the globus pallidus internus (GPi) (pallidotomy) or the ventralis intermedius (Vim) nucleus of the thalamus (thalamotomy) was the primary surgical treatment of PD.8 These procedures were applied as treatment of symptoms in refractory cases and little was available in the way of medical management for motor complications in patients with advanced PD. Stereotactic ablations focused on the pallidothalamic pathway, including the globous
Ongoing procedural enhancements
Iterative technological advances have resulted in ongoing improvements in both patient customized target identification as well as novel surgical approaches for electrode placement. These ongoing technological improvements have allowed new working paradigms to emerge. Recent advances in microelectrode recording (MER)-based targeting techniques and imaging-based targeting techniques are reviewed. Direct comparisons between various methodological approaches are sparse. Excellent results have been
Selected advances in deep brain stimulation hardware and programming
The advent of DBS for PD has led to improved quality of life for many patients. Nonetheless, significant opportunities remain for improvement in this therapy.74 Patients who have elevated energy requirements to obtain effective therapy may require frequent battery changes. Furthermore, many patients have optimal settings that are task-specific, necessitating a manual change in programming in preparation for a specific activity. The concept of closed-loop DBS holds promise to improve therapy
Summary
Since FDA approval in 1997, DBS has revolutionized the treatment of PD. Within the past decade, the technology has seen an explosion of ideas in both surgical targeting and more nuanced stimulation delivery with new devices. The ability to use intraoperative imaging, as well as DTI, has made it possible to target deep nuclei more accurately, perhaps without the need for MER. DTI targeting also may allow for electrode placement that incorporates or avoids specific fiber tracts. Furthermore,

Effects of deep brain stimulation target on the activation and suppression of action impulses
2022, Clinical NeurophysiologyCitation Excerpt :Parkinson’s Disease (PD) is a neurodegenerative disease associated with abnormal processing in the cortico-striatal motor loops (DeLong and Wichmann, 2015). Modulating the activity of this circuit through deep brain stimulation (DBS) is an established and effective treatment of PD motor symptoms (Fang and Tolleson, 2017; Kogan et al. (2019). Motor regions of the subthalamic nucleus (STN) and globus pallidus internus (GPi) are the most common targets for stimulation, demonstrating similar results in reducing bradykinesia, tremor, and rigidity, as well as producing similar global neuropsychological outcomes (Cernera et al., 2019; Peng et al., 2018; Okun et al., 2009; Dietz and Neimat, 2019).

2020, Analytica Chimica ActaCitation Excerpt :Parkinson’s disease (PD) is the prevalent neurodegenerative disorder, affecting 1% of the world population, especially with people at the older ages [1,2]. PD occurs when neuron or nerve cells in the brain area die or impaired, in particular it affects the region ‘substantia nigra’, which is known as the dopamine-producing neurons [3] (Fig. 1a). PD has also been found with severe physiological illnesses such as, spinal cord injury, multiple sclerosis, stroke, neoplastic disorders and neuronal degeneration.
