MRS and DTI evidence of progressive posterior cingulate cortex and corpus callosum injury in the hyper-acute phase after Traumatic Brain Injury (2019)
Journal Article

The posterior cingulate cortex (PCC) and corpus callosum (CC) are susceptible to trauma, but injury often evades detection. PCC Metabolic disruption may predict CC white matter tract injury and the secondary cascade responsible for progression. While...

Hierarchical heterogeneity across human cortex shapes large-scale neural dynamics (2019)
Journal Article

The large-scale organization of dynamical neural activity across cortex emerges through long-range interactions among local circuits. We hypothesized that large-scale dynamics are also shaped by heterogeneity of intrinsic local properties across cort...

How do spatially distinct frequency specific MEG networks emerge from one underlying structural connectome? The role of the structural eigenmodes (2018)
Journal Article

Functional networks obtained from magnetoencephalography (MEG) from different frequency bands show distinct spatial patterns. It remains to be elucidated how distinct spatial patterns in MEG networks emerge given a single underlying structural networ...

Automated quality control for within and between studies diffusion MRI data using a non-parametric framework for movement and distortion correction (2018)
Journal Article

Diffusion MRI data can be affected by hardware and subject-related artefacts that can adversely affect downstream analyses. Therefore, automated quality control (QC) is of great importance, especially in large population studies where visual QC is no...

Automated processing pipeline for neonatal diffusion MRI in the developing Human Connectome Project (2018)
Journal Article

The developing Human Connectome Project is set to create and make available to the scientific community a 4-dimensional map of functional and structural cerebral connectivity from 20 to 44 weeks post-menstrual age, to allow exploration of the genetic...

Whole brain comparative anatomy using connectivity blueprints (2018)
Journal Article

Comparing the brains of related species faces the challenges of establishing homologies whilst accommodating evolutionary specializations. Here we propose a general framework for understanding similarities and differences between the brains of primat... Read More about Whole brain comparative anatomy using connectivity blueprints.

Bayesian optimization of large-scale biophysical networks (2018)
Journal Article

The relationship between structure and function in the human brain is well established, but not yet well characterised. Large-scale biophysical models allow us to investigate this relationship, by leveraging structural information (e.g. derived from...

Image processing and Quality Control for the first 10,000 brain imaging datasets from UK Biobank (2017)
Journal Article

UK Biobank is a large-scale prospective epidemiological study with all data accessible to researchers worldwide. It is currently in the process of bringing back 100,000 of the original participants for brain, heart and body MRI, carotid ultrasound an...

The heritability of multi-modal connectivity in human brain activity (2017)
Journal Article

Patterns of intrinsic human brain activity exhibit a profile of functional connectivity that is associated with behaviour and cognitive performance, and deteriorates with disease. This paper investigates the relative importance of genetic factors and... Read More about The heritability of multi-modal connectivity in human brain activity.

Estimation of white matter fiber parameters from compressed multiresolution diffusion MRI using sparse Bayesian learning (2017)
Journal Article

We present a sparse Bayesian unmixing algorithm BusineX: Bayesian Unmixing for Sparse Inference-based Estimation of Fiber Crossings (X), for estimation of white matter fiber parameters from compressed (under-sampled) diffusion MRI (dMRI) data. Busine... Read More about Estimation of white matter fiber parameters from compressed multiresolution diffusion MRI using sparse Bayesian learning.

Improved tractography using asymmetric fibre orientation distributions (2017)
Journal Article

Diffusion MRI allows us to make inferences on the structural organisation of the brain by mapping water diffusion to white matter microstructure. However, such a mapping is generally ill-defined; for instance, diffusion measurements are antipodally s... Read More about Improved tractography using asymmetric fibre orientation distributions.

Building connectomes using diffusion MRI: why, how and but (2017)
Journal Article

Why has diffusion MRI become a principal modality for mapping connectomes in vivo? How do different image acquisition parameters, fiber tracking algorithms and other methodological choices affect connectome estimation? What are the main factors that...

Time-efficient and flexible design of optimized multishell HARDI diffusion (2017)
Journal Article

Purpose: Advanced diffusion magnetic resonance imaging benefits from collecting as much data as is feasible but is highly sensitive to subject motion and the risk of data loss increases with longer acquisition times. Our purpose was to create a maxim... Read More about Time-efficient and flexible design of optimized multishell HARDI diffusion.

Image quality transfer and applications in diffusion MRI (2017)
Journal Article

This paper introduces a new computational imaging technique called image quality transfer (IQT). IQT uses machine learning to transfer the rich information available from one-off experimental medical imaging devices to the abundant but lower-quality...

Studying neuroanatomy using MRI (2017)
Journal Article

The study of neuroanatomy using imaging enables key insights into how our brains function, are shaped by genes and environment, and change with development, aging, and disease. Developments in MRI acquisition, image processing, and data modelling hav... Read More about Studying neuroanatomy using MRI.
