Deep Brain Stimulation of Caudal Zona Incerta for Parkinson's Disease: One‐Year Follow‐Up and Electric Field Simulations

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objective To evaluate the effects of bilateral caudal zona incerta (cZi) deep brain stimulation (DBS) for Parkinson's disease (PD) one year after surgery and to create anatomical improvement maps based on patient‐specific simulation of the electric field.

Accelerated Detection of Viral Particles by Combining AC Electric Field Effects and Micro-Raman Spectroscopy

open access: yesSensors, 2015
A detection method that combines electric field-assisted virus capture on antibody-decorated surfaces with the “fingerprinting” capabilities of micro-Raman spectroscopy is demonstrated for the case of M13 virus in water.

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries

open access: yesAdvanced Science, EarlyView.
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

The Intraoperative Microlesion Effect Positively Correlates With the Short‐Term Clinical Effect of Deep Brain Stimulation in Parkinson's Disease

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objective During the surgical procedure of deep brain stimulation (DBS), insertion of an electrode in the subthalamic nucleus (STN) frequently causes a temporary improvement of motor symptoms, known as the microlesion effect (MLE). The objective of this study was to determine the correlation between the intraoperative MLE and the clinical ...

Batch-fabricated full glassy carbon fibers for real-time tonic and phasic dopamine detection

open access: yesFrontiers in Bioengineering and Biotechnology
Dopamine (DA) is a critical neurotransmitter that is key in regulating motor functions, motivation, and reward-related behavior. Measuring both tonic (baseline, steady-state) and phasic (rapid, burst-like) DA release is essential for elucidating the ...

Abstract Representation of Movement Parameters in Basal Ganglia Output

open access: yesAdvanced Science, EarlyView.
The basal ganglia output provides a scalable velocity/position signal across behavioral contexts, supporting the idea that these variables are represented in the brain as abstract entities rather than as fixed changes in joint angles or specific sets of body effectors.

A Review on AC-Dielectrophoresis of Nanoparticles

open access: yesMicromachines
Dielectrophoresis at the nanoscale has gained significant attention in recent years as a low-cost, rapid, efficient, and label-free technique. This method holds great promise for various interdisciplinary applications related to micro- and nanoscience ...

The reactivity of platinum microelectrodes

open access: yesPhysical Chemistry Chemical Physics, 2016
Platinum ultramicroelectrodes exhibit lower reactivity towards surface sensitive reactions than macroelectrodes, typically due to (trace) contamination, making electrochemical characterization very important for a proper comparison.

Adaptive Network Stabilization Despite Profound Structural Reorganization in Human Organotypic Cultures

open access: yesAdvanced Science, EarlyView.
Adult human organotypic cortical slices undergo marked neuronal loss, laminar disruption, and glial activation, yet their network activity progressively stabilizes after a variable period. Electrophysiology, longitudinal calcium imaging, and quantitative histology show that structurally remodeled human circuits show adaptive capacity resulting in ...

Direct visualization of microwires in hybrid depth electrodes using high‐resolution photon‐counting CT

open access: yesEpilepsia Open
Hybrid depth electrodes are increasingly being used for epilepsy monitoring and human neurophysiology research. Microwires extending from the tip of the Behnke‐Fried (BF) electrode into (sub)cortical areas allow to isolate single neurons and perform ...
