Identifying the sources of the pulse artefact in EEG recordings made inside an MR scanner (2013)
Journal Article
Mullinger, K. J., Havenhand, J., & Bowtell, R. W. (2013). Identifying the sources of the pulse artefact in EEG recordings made inside an MR scanner. NeuroImage, 71(1), https://doi.org/10.1016/j.neuroimage.2012.12.070

EEG recordings made during concurrent fMRI are confounded by the pulse artefact (PA), which although smaller than the gradient artefact is often more problematic because of its variability over multiple cardiac cycles. A better understanding of the P... Read More about Identifying the sources of the pulse artefact in EEG recordings made inside an MR scanner.

Regional structural differences across functionally parcellated Brodmann areas of human primary somatosensory cortex (2013)
Journal Article

Ultra-high-field (UHF) MRI is ideally suited for structural and functional imaging of the brain. High-resolution structural MRI can be used to map the anatomical boundaries between functional domains of the brain by identifying changes related to the...

Fiber orientation-dependent white matter contrast in gradient echo MRI (2012)
Journal Article
Wharton, S., & Bowtell, R. W. (2012). Fiber orientation-dependent white matter contrast in gradient echo MRI. Proceedings of the National Academy of Sciences, 109(45), https://doi.org/10.1073/pnas.1211075109

Recent studies have shown that there is a direct link between the orientation of the nerve fibers in white matter (WM) and the contrast observed in magnitude and phase images acquired using gradient echo MRI. Understanding the origin of this link is... Read More about Fiber orientation-dependent white matter contrast in gradient echo MRI.

Reducing the gradient artefact in simultaneous EEG-fMRI by adjusting the subject’s axial position (2011)
Journal Article
Mullinger, K. J., Yan, W. X., & Bowtell, R. W. (2011). Reducing the gradient artefact in simultaneous EEG-fMRI by adjusting the subject’s axial position. NeuroImage, 54(3), https://doi.org/10.1016/j.neuroimage.2010.09.079

Large artefacts which compromise EEG data quality are generated when electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) are carried out concurrently. The gradient artefact produced by the time-varying magnetic field gradien... Read More about Reducing the gradient artefact in simultaneous EEG-fMRI by adjusting the subject’s axial position.
