Journal Article
Balla, D. Z., Sánchez-Panchuelo, R., Wharton, S. J., Hagberg, G. E., Scheffler, K., Francis, S. T., & Bowtell, R. (2014). Functional quantitative susceptibility mapping (fQSM). NeuroImage, 100, 112-124. https://doi.org/10.1016/j.neuroimage.2014.06.011

Blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) is a powerful technique, typically based on the statistical analysis of the magnitude component of the complex time-series. Here, we additionally interrogated the p... Read More about Functional quantitative susceptibility mapping (fQSM).

A Randomized, Controlled, Double-Blind Crossover Study on the Effects of 1-L Infusions of 6% Hydroxyethyl Starch Suspended in 0.9% Saline (Voluven) and a Balanced Solution (Plasma Volume Redibag) on Blood Volume, Renal Blood Flow Velocity, and Renal Cortical Tissue Perfusion in Healthy Volunteers (2014)

Objective: We compared the effects of intravenous administration of 6% hydroxyethyl starch (maize-derived) in 0.9% saline (Voluven; Fresenius Kabi, Runcorn, United Kingdom) and a “balanced” preparation of 6% hydroxyethyl starch (potato-derived) [Plas...

Evidence that the negative BOLD response is neuronal in origin: a simultaneous EEG–BOLD–CBF study in humans (2014)
Journal Article
Mullinger, K. J., Mayhew, S. D., Bagshaw, A. P., Bowtell, R. W., & Francis, S. T. (2014). Evidence that the negative BOLD response is neuronal in origin: a simultaneous EEG–BOLD–CBF study in humans. NeuroImage, 94, https://doi.org/10.1016/j.neuroimage.2014.02.029

Unambiguous interpretation of changes in the BOLD signal is challenging because of the complex neurovascular coupling that translates changes in neuronal activity into the subsequent haemodynamic response. In particular, the neurophysiological origin... Read More about Evidence that the negative BOLD response is neuronal in origin: a simultaneous EEG–BOLD–CBF study in humans.
