Delayed M50/M100 evoked response component latency in minimally verbal/nonverbal children who have autism spectrum disorder

Molecular Autism, 2019
Abnormal auditory neuromagnetic M50 and M100 responses, reflecting primary/secondary auditory cortex processing, have been reported in children who have autism spectrum disorder (ASD).

Bayesian Opportunities for Brain–Computer Interfaces: Enhancement of the Existing Classification Algorithms and Out-of-Domain Detection

Algorithms, 2023
Bayesian neural networks (BNNs) are effective tools for a variety of tasks that allow for the estimation of the uncertainty of the model. As BNNs use prior constraints on parameters, they are better regularized and less prone to overfitting, which is a ...

Motor cortex activity predicts response alternation during sensorimotor decisions

Nature Communications, 2016
The motor cortex executes responses based on sensory choices, but it is unknown whether it also impacts response selection. Here, Pape and Siegel show that motor cortex activity present before decision making predicts responses and that this activity is ...

Epidemic models characterize seizure propagation and the effects of epilepsy surgery in individualized brain networks based on MEG and invasive EEG recordings

Scientific Reports, 2022
Epilepsy surgery is the treatment of choice for drug-resistant epilepsy patients. However, seizure-freedom is currently achieved in only 2/3 of the patients after surgery. In this study we have developed an individualized computational model based on MEG

Maturation of hemispheric specialization for face encoding during infancy and toddlerhood

Developmental Cognitive Neuroscience, 2021
Little is known about the neural processes associated with attending to social stimuli during infancy and toddlerhood. Using infant magnetoencephalography (MEG), fusiform gyrus (FFG) activity while processing Face and Non-Face stimuli was examined in 46 ...

Post-Processing for Spectral Coherence of Magnetoencephalogram Background Activity: Application to Alzheimer’s Disease [PDF]

, 2014
Estimating the connectivity between magnetoencephalogram (MEG) signals provides an excellent opportunity to analyze whole brain functional integration across a spectrum of conditions from health to disease.

The role of epidemic spreading in seizure dynamics and epilepsy surgery

Network Neuroscience, 2023
Epilepsy surgery is the treatment of choice for drug-resistant epilepsy patients, but only leads to seizure freedom for roughly two in three patients. To address this problem, we designed a patient-specific epilepsy surgery model combining large-scale ...

Present status of the MEG experiment at PSI

, 2011
We describe the present status of the MEG experiment, whose aim is to search for the lepton flavour violating (LFV) process μ +→e +γ with a sensitivity down to 10 -13. Recent theoretical calculations indicate a strong connection between LFV processes and

Ensemble de-noising of spatio-temporal EEG and MEG data [PDF]

, 1997
We present a de-noising method for spatio-temporal EEG# MEG data that incorporates prestimulus and spatial information to estimate the noise and signal energies and select a robust denoising threshold.

Activation of the left inferior frontal gyrus in the first 200 ms of reading: evidence from magnetoencephalography (MEG) [PDF]

, 2009
BACKGROUND: It is well established that the left inferior frontal gyrus plays a key role in the cerebral cortical network that supports reading and visual word recognition. Less clear is when in time this contribution begins.
