Brain Connectivity in Dystonia: Evidence from Magnetoencephalography : MEG and Dystonia

, 2023
Magnetoencephalography (MEG) detects synchronized activity within a neuronal network by measuring the magnetic field changes generated by intracellular current flow.

Detection of interictal epileptiform discharges using multiple bilateral insertions of a newly developed microcatheter‐compatible endovascular electroencephalogram electrode: A clinical feasibility trial

Epilepsia Open, EarlyView.
Abstract Objective To assess the feasibility, technical performance, and safety of a novel endovascular electroencephalogram (eEEG) electrode, EP‐01, designed for minimally invasive seizure localization in patients with drug‐resistant epilepsy. Methods This single‐center, prospective, exploratory trial enrolled five patients with drug‐resistant ...

Inter-Trial Consistency in Sensorimotor Cortex During Finger-Tapping Movements

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Optically-pumped magnetometer magnetoencephalography (OPM-MEG) is a new technology to detect neural electrophysiological signals. Inter-trial consistency (ITC) is an important indicator to characterize functional connectivity. It also provides a reliable

Representation of probabilistic outcomes during risky decision-making

Nature Communications, 2020
Goal directed behavior requires the sequential retrieval and evaluation of the multiple choices for action and their deterministic outcomes. Here, the authors report sequential, decodable probabilistic outcome representations in magnetoencephalography ...

Cortical locations of maximal spindle activity: magnetoencephalography (MEG) study [PDF]

Journal of Sleep Research, 2009
SummaryThe aim of this study was to determine the main cortical regions related to maximal spindle activity of sleep stage 2 in healthy individual subjects during a brief morning nap using magnetoencephalography (MEG). Eight volunteers (mean age: 26.1 ± 8.7, six women) all right handed, free of any medical psychiatric or sleep disorders were studied ...

Characteristics and long‐term outcomes of children with confirmed focal cortical dysplasia type 1 after epilepsy surgery: A population‐based study

Epilepsia Open, EarlyView.
Abstract Objective Focal cortical dysplasia type 1 (FCD1) is a rare and heterogeneous cause of drug‐resistant epilepsy (DRE) in children. Its clinical characteristics remain poorly understood, and surgical outcomes may be less favorable than in FCD2. We conducted a population‐based study to characterize the clinical presentation and long‐term seizure ...

Brain–Computer Interfaces: The Dawn of a New Era in Disease Treatment

Exploration, EarlyView.
This study investigates the potential of brain–computer interface (BCI) technology in treating neuropsychiatric disorders, such as movement and communication barriers. Our review examines the history, signal paradigms, and diverse applications of BCI while also discussing ongoing research into novel materials and emerging technologies that offer ...

Dynamical Mean Field approximation of a canonical cortical model for studying inter-population synchrony

, 2011
The goal of this paper is twofold. We propose and explore a model to study the synchronization among populations in the canonical model of the neocortex proposed previously by (R.J. Douglas, K.A.C. Martin, A functional microcircuit for cat visual cortex.

Somatosensory Disturbance and Long‐Term Exposure to Methylmercury: A Comprehensive Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chronic exposure to methylmercury remains a significant public health concern, particularly in populations with high fish consumption. Somatosensory disturbances are among the most frequently reported neurological manifestations, even at exposure levels below internationally established safety thresholds. This review aims to synthesize current
