We present a systematic study on the effects of electropolymerization parameters of polypyrrole-dodecylbenzenesulfonate (PPy(DBS)) surfaces on the flattening behaviors of organic droplets during reduction and oxidation (redox). PPy(DBS) surfaces were fabricated under varying electropolymerization conditions, including voltage, surface charge density, and dopant electrolyte (DBS-) concentration....

Deep-brain stimulation (DBS) is a clinical intervention that has provided remarkable therapeutic benefits for otherwise treatment-resistant movement and affective disorders. The resulting direct causal manipulation of both local and distributed brain networks is not only clinically helpful but can also help to provide novel fundamental insights into brain function. In particular, DBS can be use...

BACKGROUND Parkinson's disease (PD) is a common neurodegenerative disorder that affects many people every year. Deep brain stimulation (DBS) is an effective nonpharmacological method to treat PD motor symptoms. This meta-analysis was conducted to evaluate the efficacy of subthalamic nucleus (STN)-DBS versus globus pallidus internus (GPi)-DBS in treating advanced PD. METHODS Controlled clinica...

In addition to motor symptoms, patients with Parkinson's disease (PD) show deficits in sensory processing. These deficits are thought to result from deficient gating of sensory information due to basal ganglia dysfunction in PD. Deep brain stimulation of the subthalamic nucleus (STN-DBS) has been shown to improve sensory deficits in PD, e.g. STN-DBS normalizes the perception of urinary bladder ...

BACKGROUND Deep-brain stimulation (DBS) is an established treatment for medically refractory essential tremor (ET). This article reviews the current evidence supporting the efficacy and safety of DBS targets, including the ventral intermediate (VIM) nucleus and posterior subthalamic area (PSA) in treatment of ET. METHODS A structured PubMed search was performed through December 2012 with keyw...

BACKGROUND Some patients with deep brain stimulation (DBS), where removal of implants is indicated due to hardware related infections, are not candidates for later re-implantation. In these patients a rescue lesion through the DBS electrode has been suggested as an option. In this case report we present a patient where a pallidotomy was performed using the DBS electrode. CASE DESCRIPTION An e...

Deep brain stimulation (DBS) is an important effective treatment for pharmacoresistant epilepsy, but its mechanism is still not clear. In clinical application, the possible effects and mechanisms DBS in treatment of epilepsy are different according to different stimulation parameters. We reviewed the mechanisms of DBS in different frequencies including high frequency and low frequency in the tr...

Deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) is a novel therapy developed to treat Parkinson's disease. We report a patient who underwent bilateral DBS of the PPN and subthalamic nucleus (STN). He suffered from freezing of gait (FOG), bradykinesia, rigidity and mild tremors. The patient underwent bilateral DBS of the PPN and STN. We compared the benefits of PPN-DBS and STN...

The electronic g-tensor calculations are performed for dangling bonds (DBs) introduced into nanodiamonds (NDs) with four different functional groups on their surfaces. For hydrogenated and fluorinated NDs, it is found that g-shifts of the latter vary in a much wider range, same also true total energy differences between highest lowest DBs. In addition, shown shape NDs significantly impacts ener...

High-frequency stimulation is known to entrain spike activity downstream and upstream of several clinical deep brain stimulation (DBS) targets, including the cerebellar-receiving area of thalamus (VPLo), subthalamic nucleus (STN), and globus pallidus (GP). Less understood are the fidelity of entrainment to each stimulus pulse, whether entrainment patterns are stationary over time, and how respo...
