Optically pumped magnetoencephalography in epilepsy
Annals of Clinical and Translational Neurology, 2020 We demonstrate the first use of Optically Pumped Magnetoencephalography (OP‐MEG) in an epilepsy patient with unrestricted head movement. Current clinical MEG uses a traditional SQUID system, where sensors are cryogenically cooled and housed in a helmet ...

A two-way regularization method for MEG source reconstruction [PDF]
, 2012 The MEG inverse problem refers to the reconstruction of the neural activity of the brain from magnetoencephalography (MEG) measurements. We propose a two-way regularization (TWR) method to solve the MEG inverse problem under the assumptions that only a ...

MEG Source Localization via Deep Learning
Sensors, 2021 We present a deep learning solution to the problem of localization of magnetoencephalography (MEG) brain signals. The proposed deep model architectures are tuned to single and multiple time point MEG data, and can estimate varying numbers of dipole ...

A tool for functional brain imaging with lifespan compliance
Nature Communications, 2019 Magnetoencephalography (MEG) recordings are sensitive to movement and therefore are especially challenging with young participants. Here the authors develop a wearable MEG system based on a modified bicycle helmet, which enables reliable recordings in ...

Independent component approach to the analysis of EEG and MEG recordings [PDF]
, 2000 Multichannel recordings of the electromagnetic fields emerging from neural currents in the brain generate large amounts of data. Suitable feature extraction methods are, therefore, useful to facilitate the representation and interpretation of the data ...

Cortical locations of maximal spindle activity: magnetoencephalography (MEG) study [PDF]
Journal of Sleep Research, 2009 SummaryThe aim of this study was to determine the main cortical regions related to maximal spindle activity of sleep stage 2 in healthy individual subjects during a brief morning nap using magnetoencephalography (MEG). Eight volunteers (mean age: 26.1 ± 8.7, six women) all right handed, free of any medical psychiatric or sleep disorders were studied ...

Detection of temporal-lobe epilepsy with the physiological responses to fear and anxiety [PDF]
, 2020 Epilepsy is a neurological disease caused by an abnormal neuronal activity on a region of the brain, which provokes seizures and the loss of consciousness to its patients. Epilepsy can be very disabling, since patients do not know when crisis or seizures
