The spatial extent of anatomical connections within the thalamus varies across the cortical hierarchy in humans and macaques (2024)
Preprint / Working Paper
Howell, A. M., Warrington, S., Fonteneau, C., Cho, Y. T., Sotiropoulos, S. N., Murray, J. D., & Anticevic, A. The spatial extent of anatomical connections within the thalamus varies across the cortical hierarchy in humans and macaques

Each cortical area has a distinct pattern of anatomical connections within the thalamus, a central subcortical structure composed of functionally and structurally distinct nuclei. Previous studies have suggested that certain cortical areas may have m...

Non-human primates are extensively used in neuroscience research as models of the human brain, with the rhesus macaque being a prominent example. We have previously introduced a set of tractography protocols (XTRACT) for reconstructing 42 correspondi...

On the stability of canonical correlation analysis and partial least squares with application to brain-behavior associations (2024)
Journal Article

On the stability of canonical correlation analysis and partial least squares with application to brain-behavior associations. Communications Biology, 7(1), Article 217. https://doi.org/10.1038/s42003-024-05869-4

Associations between datasets can be discovered through multivariate methods like Canonical Correlation Analysis (CCA) or Partial Least Squares (PLS). A requisite property for interpretability and generalizability of CCA/PLS associations is stability...

A resource for development and comparison of multimodal brain 3T MRI harmonisation approaches (2023)
Journal Article
Warrington, S., Ntata, A., Mougin, O., Campbell, J., Torchi, A., Craig, M., …Sotiropoulos, S. N. (2023). A resource for development and comparison of multimodal brain 3T MRI harmonisation approaches. Imaging Neuroscience, 1(2023), 1-27. https://doi.org/10.1162/imag_a_00042

Despite the huge potential of magnetic resonance imaging (MRI) in mapping and exploring the brain, MRI measures can often be limited in their consistency, reproducibility and accuracy which subsequently restricts their quantifiability. Nuisance nonbi... Read More about A resource for development and comparison of multimodal brain 3T MRI harmonisation approaches.

Concurrent mapping of brain ontogeny and phylogeny within a common space: standardised tractography and applications (2022)
Journal Article
Warrington, S., Thompson, E., Bastiani, M., Dubois, J., Baxter, L., Slater, R., …Sotiropoulos, S. N. (2022). Concurrent mapping of brain ontogeny and phylogeny within a common space: standardised tractography and applications. Science Advances, 8(42), Article eabq2. https://doi.org/10.1126/sciadv.abq2022

Developmental and evolutionary effects on brain organization are complex, yet linked, as evidenced by the correspondence in cortical area expansion across these vastly different time scales. However, it is still not possible to study concurrently the... Read More about Concurrent mapping of brain ontogeny and phylogeny within a common space: standardised tractography and applications.

Predicting time-resolved electrophysiological brain networks from structural eigenmodes (2022)
Journal Article

How temporal modulations in functional interactions are shaped by the underlying anatomical connections remains an open question. Here, we analyse the role of structural eigenmodes, in the formation and dissolution of temporally evolving functional b...

White matter bundle segmentation using diffusion MRI fiber tractography has become the method of choice to identify white matter fiber pathways in vivo in human brains. However, like other analyses of complex data, there is considerable variability i...
