Addressing challenges of high spatial resolution UHF fMRI for group analysis of higher‐order cognitive tasks: An inter‐sensory task directing attention between visual and somatosensory domains. Human Brain Mapping, 40(4), 1298-1316. https://doi.org/10.1002/hbm.24450

Functional MRI at ultra-high field (UHF, ?7T) provides significant increases in BOLD contrast-to-noise ratio (CNR) compared with conventional field strength (3T), and has been exploited for reduced field-of-view, high spatial resolution mapping of pr...

Exploring the relative efficacy of motion artefact correction techniques for EEG data acquired during simultaneous fMRI (2018)
Journal Article
Alexander, D. J., Smith, J. A., Spencer, G. S., Jorge, J., Bowtell, R., & Mullinger, K. J. (2019). Exploring the relative efficacy of motion artefact correction techniques for EEG data acquired during simultaneous fMRI. Human Brain Mapping, 40(2), 578-596. https://doi.org/10.1002/hbm.24396

Simultaneous EEG-fMRI allows multi-parametric characterisation of brain function, in principle enabling a more complete understanding of brain responses; unfortunately the hostile MRI environment severely reduces EEG data quality. Simply eliminating... Read More about Exploring the relative efficacy of motion artefact correction techniques for EEG data acquired during simultaneous fMRI.

Changes in electrophysiological markers of cognitive control after administration of galantamine (2018)
Journal Article
Robson, S. E., Gascoyne, L. E., Mullinger, K. J., Robson, S., Kumar, J., O'Neill, G. C., …Liddle, P. F. (2018). Changes in electrophysiological markers of cognitive control after administration of galantamine. NeuroImage: Clinical, 20, 228-235. https://doi.org/10.1016/j.nicl.2018.07.019

© 2018 The healthy brain is able to maintain a stable balance between bottom-up sensory processing and top-down cognitive control. The neurotransmitter acetylcholine plays a substantial role in this. Disruption of this balance could contribute to sym... Read More about Changes in electrophysiological markers of cognitive control after administration of galantamine.

Relationships Between Neuronal Oscillatory Amplitude and Dynamic Functional Connectivity (2018)
Journal Article
Tewarie, P., Hunt, B. A. E., O'Neill, G. C., Byrne, A., Aquino, K., Bauer, M., …Brookes, M. J. (2018). Relationships Between Neuronal Oscillatory Amplitude and Dynamic Functional Connectivity. Cerebral Cortex, 29(6), 2668-2681. https://doi.org/10.1093/cercor/bhy136

Event related fluctuations of neural oscillatory amplitude are reported widely in the context of cognitive processing and are typically interpreted as a marker of brain ‘activity’. However, the precise nature of these effects remains unclear; in part... Read More about Relationships Between Neuronal Oscillatory Amplitude and Dynamic Functional Connectivity.

Moving magnetoencephalography towards real-world applications with a wearable system (2018)
Journal Article
Boto, E., Holmes, N., Leggett, J., Roberts, G., Shah, V., Meyer, S. S., …Brookes, M. J. (2018). Moving magnetoencephalography towards real-world applications with a wearable system. Nature, 555, 657-661. https://doi.org/10.1038/nature26147

Imaging human brain function with techniques such as magnetoencephalography1 (MEG) typically requires a subject to perform tasks whilst their head remains still within a restrictive scanner. This artificial environment makes the technique inaccessibl... Read More about Moving magnetoencephalography towards real-world applications with a wearable system.

Exploring the origins of EEG motion artefacts during simultaneous fMRI acquisition: implications for motion artefact correction (2018)
Journal Article
Spencer, G. S., Smith, J. A., Chowdhury, M. E., Bowtell, R. W., & Mullinger, K. J. (in press). Exploring the origins of EEG motion artefacts during simultaneous fMRI acquisition: implications for motion artefact correction. NeuroImage, 173, https://doi.org/10.1016/j.neuroimage.2018.02.034

Motion artefacts (MAs) are induced within EEG data collected simultaneously with fMRI when the subject’s head rotates relative to the magnetic field. The effects of these artefacts have generally been ameliorated by removing periods of data during wh...

Exploring the advantages of multiband fMRI with simultaneous EEG to investigate coupling between gamma frequency neural activity and the BOLD response in humans (2018)
Journal Article

Exploring the advantages of multiband fMRI with simultaneous EEG to investigate coupling between gamma frequency neural activity and the BOLD response in humans. Human Brain Mapping, 39(4), 1673-1687. https://doi.org/10.1002/hbm.23943

We established an optimal combination of EEG recording during sparse multiband (MB) fMRI that preserves high resolution, whole brain fMRI coverage whilst enabling broad-band EEG recordings which are uncorrupted by MRI gradient artefacts (GAs). We fir... Read More about Exploring the advantages of multiband fMRI with simultaneous EEG to investigate coupling between gamma frequency neural activity and the BOLD response in humans.
