Interrater reliability in visual identification of interictal high-frequency oscillations on electrocorticography and scalp EEG. [PDF]

, 2018
High-frequency oscillations (HFOs), including ripples (Rs) and fast ripples (FRs), are promising biomarkers of epileptogenesis, but their clinical utility is limited by the lack of a standardized approach to identification.

Multi‐Scale Modeling of a 3D Soft Magnetoelectric Patch for Wireless Nerve Stimulation

Advanced Materials Interfaces, EarlyView.
Core‐shell, magnetoelectric nanoparticles (MENPs) can serve as wireless electric nano‐sources, thanks to their ability to generate high levels of electricity, when stimulated by a human‐safe external magnetic field. By combining MENPs with soft, biocompatible polymeric matrices and optimizing its composite configuration and electrical behavior via ...

Trichilemmal Carcinoma of the Scalp

Online Journal of Health & Allied Sciences, 2020
Trichilemmal carcinoma is a rare hair follicle tumour which develops from the outer root sheath of the hair follicle. It is thought to occur from a malignant transformation of a benign Trichilemmoma and is usually found on sun-exposed areas such face ...

Volume Conduction Influences Scalp-Based Connectivity Estimates

Frontiers in Computational Neuroscience, 2016
Electroencephalographic (EEG) signals recorded from the scalp surface are generally highly correlated. Each channel is a linear mixture of concurrently active brain and non-brain electrical sources whose activities are volume conducted to the scalp ...

Upconversion‐Based Remote Deep Brain Modulation for Therapeutic Dissection of Parkinson's Disease

Advanced Therapeutics, EarlyView.
An upconversion‐based wireless optogenetic strategy enables an all‐optical deep brain modulation solution for treating Parkinson's disease in rodent animals without using electronics or any tethered cables, providing experimental evidence supporting a therapeutic mechanism of STN‐DBS by disruption of anterograde signal transmission along the indirect ...

Sampling theory for spatial field sensing: Application to electro- and magnetoencephalography [PDF]

arXiv, 2019
We present a theoretical framework for analyzing spatial sampling of fields in three-dimensional space. The framework bridges Shannon's sampling and information theory to Bayesian probabilistic inference and experimental design. Based on the theory, we present an approach for optimal sampling on curved surfaces and analyze spatial sampling of EEG as ...

Prediction of Memory Retrieval Performance Using Ear-EEG Signals [PDF]

arXiv, 2020
Many studies have explored brain signals during the performance of a memory task to predict later remembered items. However, prediction methods are still poorly used in real life and are not practical due to the use of electroencephalography (EEG) recorded from the scalp.

The inferior occipital gyrus is a major cortical source of the face‐evoked N170: Evidence from simultaneous scalp and intracerebral human recordings

Human Brain Mapping, 2018
The sudden onset of a face image leads to a prominent face‐selective response in human scalp electroencephalographic (EEG) recordings, peaking 170 ms after stimulus onset at occipito–temporal (OT) scalp sites: the N170 (or M170 in magnetoencephalography).

Lecithin Alleviates Memory Deficits and Muscle Attenuation in Chinese Older Adults and SAMP8 Mice

Advanced Science, EarlyView.
This study opens a new avenue for safeguarding cognition and muscle health, averting disability in older age, and treating age‐related pathologies through lecithin supplementation. It serves as a promising nonpharmacological intervention for the crosstalk of muscle and cognition.
