Zhu S, Huszar I, Cottaar M, Daubney G, Eichert N, Hanayik T, et al.
Med Image Anal
. 2025 Mar;
102:103498.
PMID: 40086183
Mapping how neurons are structurally wired into whole-brain networks can be challenging, particularly in larger brains where 3D microscopy is not available. Multi-modal datasets combining MRI and microscopy provide a...

. 2024 Jan;
91(6):2229-2246.
PMID: 38265152
Purpose: Dynamic (2D) MRS is a collection of techniques where acquisitions of spectra are repeated under varying experimental or physiological conditions. Dynamic MRS comprises a rich set of contrasts, including...

PMID: 37468455
Understanding brain structure and function often requires combining data across different modalities and scales to link microscale cellular structures to macroscale features of whole brain organisation. Here we introduce the...

Neuroimage
. 2022 Aug;
262:119535.
PMID: 35931306
To estimate microstructure-related parameters from diffusion MRI data, biophysical models make strong, simplifying assumptions about the underlying tissue. The extent to which many of these assumptions are valid remains an...

Nat Commun
. 2022 Jul;
13(1):4253.
PMID: 35869067
Myelination has been increasingly implicated in the function and dysfunction of the adult human brain. Although it is known that axon myelination shapes axon physiology in animal models, it is...

. 2022 Jul;
260:119452.
PMID: 35803473
Biophysical models that attempt to infer real-world quantities from data usually have many free parameters. This over-parameterisation can result in degeneracies in model inversion and render parameter estimation ill-posed. However,...

Cell Rep
. 2022 Jun;
39(11):110951.
PMID: 35705046
Synaptic plasticity is required for learning and follows Hebb's rule, the computational principle underpinning associative learning. In recent years, a complementary type of brain plasticity has been identified in myelinated...

. 2021 Nov;
145:187-200.
PMID: 34742100
Several studies have established specific relationships between White Matter (WM) and behaviour. However, these studies have typically focussed on fractional anisotropy (FA), a neuroimaging metric that is sensitive to multiple...

Quantifying myelin in crossing fibers using diffusion-prepared phase imaging: Theory and simulations
Cottaar M, Wu W, Tendler B, Nagy Z, Miller K, Jbabdi S
Magn Reson Med
. 2021 Jul;
86(5):2618-2634.
PMID: 34254349
Purpose: Myelin has long been the target of neuroimaging research. However, most available techniques can only provide a voxel-averaged estimate of myelin content. In the human brain, white matter fiber...

PMID: 33436528
The World Health Organization promotes physical exercise and a healthy lifestyle as means to improve youth development. However, relationships between physical lifestyle and human brain development are not fully understood....
