Effects of various food ingredients on gall bladder emptying (2013)
Journal Article
Marciani, L., Cox, E., Hoad, C., Totman, J. J., Costigan, C., Singh, G., …Spiller, R. C. (2013). Effects of various food ingredients on gall bladder emptying. European Journal of Clinical Nutrition, 67(11), https://doi.org/10.1038/ejcn.2013.168

Background/objectives: The emptying of the gall bladder in response to feeding is pivotal for the digestion of fat, but the role of various food ingredients in contracting the gall bladder postprandially is not well understood. We hypothesized that d... Read More about Effects of various food ingredients on gall bladder emptying.

Calibrated BOLD using direct measurement of changes in venous oxygenation (2012)
Journal Article
Driver, I. D., Hall, E. L., Wharton, S. J., Pritchard, S. E., Francis, S. T., & Gowland, P. A. (2012). Calibrated BOLD using direct measurement of changes in venous oxygenation. NeuroImage, 63(3), https://doi.org/10.1016/j.neuroimage.2012.08.045

Calibration of the BOLD signal is potentially of great value in providing a closer measure of the underlying changes in brain function related to neuronal activity than the BOLD signal alone, but current approaches rely on an assumed relationship bet...

Motion-related artefacts in EEG predict neuronally plausible patterns of activation in fMRI data (2012)
Journal Article
Jansen, M., White, T. P., Mullinger, K. J., Liddle, E. B., Gowland, P. A., Francis, S. T., …Liddle, P. F. (2012). Motion-related artefacts in EEG predict neuronally plausible patterns of activation in fMRI data. NeuroImage, 59(1), https://doi.org/10.1016/j.neuroimage.2011.06.094

The simultaneous acquisition and subsequent analysis of EEG and fMRI data is challenging owing to increased noise levels in the EEG data. A common method to integrate data from these two modalities is to use aspects of the EEG data, such as the ampli...

The change in cerebrovascular reactivity between 3T and 7T measured using graded hypercapnia (2010)
Journal Article
Driver, I., Blockley, N., Fisher, J., Francis, S., & Gowland, P. A. (2010). The change in cerebrovascular reactivity between 3T and 7T measured using graded hypercapnia. NeuroImage, 51(1), https://doi.org/10.1016/j.neuroimage.2009.12.113

Mapping cerebrovascular reactivity (CVR) to hypercapnia is important both clinically and for improved understanding of the haemodynamic properties of the BOLD effect. In this work BOLD/R2* CVR was investigated by using a device which provided small,... Read More about The change in cerebrovascular reactivity between 3T and 7T measured using graded hypercapnia.
