Journal ArticleDOI
Moving magnetoencephalography towards real-world applications with a wearable system.
Elena Boto,Niall Holmes,James Leggett,Gillian Roberts,Vishal Shah,Sofie S. Meyer,Sofie S. Meyer,Leonardo Duque Muñoz,Karen J. Mullinger,Karen J. Mullinger,Tim M. Tierney,Sven Bestmann,Gareth R. Barnes,Richard Bowtell,Matthew J. Brookes +14 more
TL;DR: A magnetoencephalography system that can be worn like a helmet, allowing free and natural movement during scanning, with myriad applications such as characterization of the neurodevelopmental connectome, imaging subjects moving naturally in a virtual environment and investigating the pathophysiology of movement disorders.
Journal ArticleDOI
Properties of the ballistocardiogram artefact as revealed by EEG recordings at 1.5, 3 and 7 T static magnetic field strength.
TL;DR: The results confirm that the amplitude of the BCG artefact is a function of the static magnetic field strength and that typical independent components could be more easily identified when ICA was applied after channel-wise BCG correction.
Journal ArticleDOI
Evidence that the negative BOLD response is neuronal in origin: A simultaneous EEG–BOLD–CBF study in humans
Karen J. Mullinger,Karen J. Mullinger,Stephen D. Mayhew,Andrew P. Bagshaw,Richard Bowtell,Susan T. Francis +5 more
TL;DR: The results suggest that a neuronal mechanism underlies the negative BOLD response, but that the NBR may originate from a different neurovascular coupling mechanism to the PBR, suggesting that caution should be taken in assuming the N BR simply represents the neurophysiological inverse of the P BR.
Journal ArticleDOI
Poststimulus undershoots in cerebral blood flow and BOLD fMRI responses are modulated by poststimulus neuronal activity
TL;DR: In this paper, the authors used simultaneous recordings of EEG with BOLD and cerebral blood flow (CBF) fMRI during unilateral median nerve stimulation to show that the post-stimulus fMRI signal is neuronally modulated.
Journal ArticleDOI
Alpha/beta power decreases track the fidelity of stimulus-specific information
Benjamin J. Griffiths,Stephen D. Mayhew,Karen J. Mullinger,Karen J. Mullinger,João Jorge,Ian Charest,Maria Wimber,Simon Hanslmayr +7 more
TL;DR: In this paper, the authors quantified the amount of stimulus-specific information represented within the BOLD signal on every trial, and found a significant negative correlation which indicated that as post-stimulus alpha/beta power decreased, stimulus specific information increased.
