EEG/MEG source imaging of deep brain activity within the maximum entropy on the mean framework: Simulations and validation in epilepsy

Human Brain Mapping, Volume 45, Issue 10, July 15, 2024.
We proposed depth‐weighted Maximum Entropy on the Mean (MEM) methods for EEG/MEG source imaging and evaluated using realistic EEG/MEG simulations and EEG/MEG recordings from patients with focal epilepsy. The proposed method improved localization for deep sources without worsening the superficial source reconstructions compared to standard MEM and depth

Effects of endogenous testosterone on oscillatory activity during verbal working memory in youth

Human Brain Mapping, Volume 45, Issue 10, July 15, 2024.
During puberty, endogenous testosterone levels rise. We examined whether these increases in testosterone are associated with developmental changes, controlling for age, in the neural oscillatory dynamics serving verbal working memory. Results showed that alpha and theta oscillatory responses were modulated by testosterone levels across multiple regions

SJÅ MEG, TRU MEG, HJELP MEG!

, 2016
Tittel: SJÅ MEG, TRU MEG, HJELP MEG! Bakgrunn: Myalgisk encefalopati oppsto i 1956 (Piro & Midsen, 1999) og er verdens medisinske mest omstridte sykdom hvor det er vanskelig å fastslå forekomsten av ME (Jelstad, 2011). Den rapporterte forekomsten ligger på til 0,2- 0,4% ved bruk av Canada- og Fukudakriteriene (se vedlegg 3).

Optimal gamma‐band entrainment of visual cortex

Human Brain Mapping, Volume 45, Issue 10, July 15, 2024.
Visual entrainment of primary visual cortex was robust across three different driving frequencies in the gamma‐band (32, 40, 48 Hz). This entrainment of primary visual cortex was strongest for the 32 and 40 Hz, relative to 48 Hz, driving frequencies.

Se meg, lytt til meg, anerkjenn meg

, 2021
Introduksjon Det sosiale samspillet er grunnleggende for barnets vekst og utvikling, og et viktig mål i nyfødtomsorgen. Faktorer relatert til barnet og foreldre selv, sykepleier og omgivelsene kan prege samspillet i den nye familien. Nå er Covid-19-pandemien en tilleggsfaktor som kan påvirke samspillet, herunder ved innføring av smittevernstiltak ...

Se meg, vær med meg og forstå meg

, 2020
Hensikt: Studiens hensikt er å belyse hvordan sykepleier i sykehjem kan bidra til å redusere bruk av tvang mot pasienter med demens som har utfordrende atferd. Metode: Det er brukt systematisk litteraturstudie som metode med innhenting av 8 fagfellevurderte forskningsartikler, hovedsakelig fra Skandinavia, men også fra USA og Storbritannia.

Disentangling High-Paced Alternating I/O in Gaze-Based Interaction

IEEE Access
Gaze-based input to machines utilizes the ability of eye-gaze to serve as a user’s “output.” However, gaze should also support information flow in the opposite direction, namely, “input” to the user’s visual ...

The MEG spectrometer at PSI [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2010
The MEG experiment is designed to search the Lepton Flavor Violating process $μ\to e^+γ$ \cite{mori-1999,meg2007-baldini}. This search requires a high intensity muon beam stopping in a thin target with the maximum rate compatible with the background from combinatorial events.

Magnetoencephalography Atlas Viewer for Dipole Localization and Viewing

Journal of Imaging
Magnetoencephalography (MEG) is a noninvasive neuroimaging technique widely recognized for epilepsy and tumor mapping. MEG clinical reporting requires a multidisciplinary team, including expert input regarding each dipole’s anatomic localization.

Magnetoencephalographic study of hand and foot sensorimotor organization in 325 consecutive patients evaluated for tumor or epilepsy surgery

NeuroImage: Clinical, 2016
Objectives: The presence of intracranial lesions or epilepsy may lead to functional reorganization and hemispheric lateralization. We applied a clinical magnetoencephalography (MEG) protocol for the localization of the contralateral and ipsilateral S1 ...
