Refining Detection of Subclinical Epileptiform Activity in Alzheimer's Disease: A Case–Control Study and Call for a Consensus

Annals of Neurology, Volume 99, Issue 4, Page 1046-1058, April 2026.
[Color figure can be viewed at www.annalsofneurology.org] Objective Sleep‐predominant network hyperexcitability is increasingly recognized as a potential disease‐accelerating comorbidity in Alzheimer's disease (AD). However, its prevalence and risk‐factors remain debated, largely due to cohort‐specific and methodological differences across studies.

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

Microfabricated Optically-Pumped Magnetometers for Biomagnetic Applications

Journal of Physics: Conference Series, 2016
We report on the progress in developing microfabricated optically-pumped magnetometer arrays for imaging applications. We have improved our sensitivities by several orders of magnitude in the last ten years. Now, our zero-field magnetometers reach noise values below 15 fT/Hz1/2.

Tailorable Curie Temperature in Zinc Ferrite Nanoparticles With Finely Tunable Induction Heating Profiles Between Room Temperature and 250°C

Small, Volume 22, Issue 21, 13 April 2026.
A spray‐drying‐based synthesis enables the formation of zinc ferrite nanoparticles with customizable induction heating from room temperature to 250°C by varying the zinc content and postsynthesis annealing temperatures. The aqueous dispersions are colloidally stable and heat up to biologically relevant thresholds. Hence, this approach offers a scalable

Revolutionizing Pediatric Neurophysiology With Magnetoencephalography

Psychophysiology, Volume 63, Issue 4, April 2026.
ABSTRACT This paper considers the current and future use of magnetoencephalography (MEG) for assessing neural activity in children (birth to 18 years old), including the well‐established use of SQUID (Superconducting QUantum Interference Device) MEG technology as well as the very rapidly developing Optically Pumped Magnetometry (OPM) technology.

Optically pumped alkali magnetometers for biomedical applications [PDF]

Europhysics News, 2012
20 Optically pumped atomic magnetometers measure the Larmor frequency νL at which the bulk magnetization of a spin-polarized alkali metal vapour in a glass cell precesses around the field of interest B → 0. The precession frequency is related to the modulus of the magnetic field by νL=(γ/2π)|B → 0|, where γ/2π≈3.5Hz/nT for 133Cs, so that the magnetic ...
