Journal Article
Hernandez-Fernandez, M., Reguly, I., Jbabdi, S., Giles, M., Smith, S., & Sotiropoulos, S. N. (2019). Using GPUs to accelerate computational diffusion MRI: from microstructure estimation to tractography and connectomes. NeuroImage, 188, 598-615. https://doi.org/10.1016/j.neuroimage.2018.12.015

The great potential of computational diffusion MRI (dMRI) relies on indirect inference of tissue microstructure and brain connections, since modelling and tractography frameworks map diffusion measurements to neuroanatomical features. This mapping ho... Read More about Using GPUs to accelerate computational diffusion MRI: from microstructure estimation to tractography and connectomes.

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.

The Noise Exposure Structured Interview (NESI): an instrument for the comprehensive estimation of lifetime noise exposure (2018)
Journal Article

Lifetime noise exposure is generally quantified by self report. The accuracy of retrospective self report is limited by respondent recall, but is also bound to be influenced by reporting procedures. Such procedures are of variable quality in current... Read More about The Noise Exposure Structured Interview (NESI): an instrument for the comprehensive estimation of lifetime noise exposure.
