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.

Automatic Spatial Calibration of Ultra-Low-Field MRI for High-Accuracy Hybrid MEG--MRI
With a hybrid MEG--MRI device that uses the same sensors for both modalities, the co-registration of MRI and MEG data can be replaced by an automatic calibration step. Based on the highly accurate signal model of ultra-low-field (ULF) MRI, we introduce a

Network perspectives on epilepsy using EEG/MEG source connectivity [PDF]
The evolution of EEG/MEG source connectivity is both, a promising, and controversial advance in the characterization of epileptic brain activity. In this narrative review we elucidate the potential of this technology to provide an intuitive view of the ...

Fetal Pain Perception: Legislative Assertions and Developmental Neuroscience
ABSTRACT Background Pain perception is a conscious experience, but neither pain nor consciousness is defined in the developing human fetus. Emergent consciousness may be regarded as a phenomenon that ultimately arises from an essential minimum of functional neuronal connectivity. Proposed U.S.

Evidence for the role of magnetic source imaging in the presurgical evaluation of refractory epilepsy patients [PDF]
Magnetoencephalography (MEG) in the field of epilepsy has multiple advantages; just like electroencephalography (EEG), MEG is able to measure the epilepsy specific information (i.e., the brain activity reflecting seizures and/or interictal epileptiform ...

Attentional Enhancement of Auditory Mismatch Responses: a DCM/MEG Study. [PDF]
Despite similar behavioral effects, attention and expectation influence evoked responses differently: Attention typically enhances event-related responses, whereas expectation reduces them.

Abstract Objective Stereoelectroencephalography (sEEG) is commonly employed in the workup for epilepsy surgery in patients with focal drug‐resistant epilepsy (DRE). Intracranial hemorrhage is a known complication, with reported incidence rates ranging from .9% to 19.1%. Rarely, pseudoaneurysms have been reported in literature as a potential cause. This

Abstract High‐frequency oscillations (HFOs) were discovered more than 20 years ago, and since then they have been studied intensively in the context of epilepsy. HFOs encompass a broad spectrum of oscillations, typically ranging from 80 Hz to several kHz, that include both normal and pathological oscillations, documented in people with epilepsy and ...

Measuring Human Auditory Evoked Fields with a Flexible Multi-Channel OPM-Based MEG System
Background: Magnetoencephalography (MEG) is a non-invasive imaging technique for directly measuring the external magnetic field generated from synchronously activated pyramidal neurons in the brain.
