‼️NEW PREPRINT‼️

What if you could take a normal 3T T1w MRI and make it look like it was acquired from a 7T scanner?

That's exactly what we do using AI in our new preprint!

This cures my FOMO about missing #OHBM2025 ... somewhat 🧠

Imaging cortical layers to understand brain as network organ This spatial scale, bridging cells and brain areas, has been overlooked in human brain research. But advances in fMRI technology are changing that.

ICYMI: In this essay for our Future of fMRI series, Laurentius Huber @layerfmri.bsky.social explains how new advances in functional MRI could help to connect cells and brain areas at the mesoscopic scale.

fMRI can do more than you think Advances in brain imaging technology provide new and different information about the brain.

Taking full advantage of new advances in brain imaging technology will require more collaboration between engineers and neuroscientists, writes @lauradata.bsky.social in the latest for our human neurotechnology series.

Huge congratulations Audrey!! This is very important work. It's nice to see how robust these developmental gradients are across datasets - underscoring the need to look beyond tract-averaged measures 😊

Head Motion in Diffusion Magnetic Resonance Imaging: Quantification, Mitigation, and Structural Associations in Large, Cross‐Sectional Datasets Across the Lifespan We characterized motion during diffusion MRI scans across 16,995 image sessions and find that (1) modern preprocessing pipelines effectively mitigate motion to the point where biases are not detectab....

It's hard to overstate what a big deal this paper is: onlinelibrary.wiley.com/doi/10.1002/.... Head motion in dMRI is NOT like head motion in BOLD.

This is figure 1, which shows the relationship between sleep and circadian dysfunction in neurodevelopmental disorders.

Considering the interconnected nature of social identities in neuroimaging research - Nature Neuroscience Individual variability in behavior is influenced by social identities. Here, Dhamala et al. discuss the need to incorporate social identities in neuroimaging studies of behavior and explore how to fos...

Recent executive orders targeting marginalized communities underscore the urgent need for inclusive biomedical research.

Our latest work, now out in print, explores how interconnected social identities impact brain biology and mental health, providing a roadmap for more equitable research.

Transdiagnostic thinking could accelerate autism science Our tendency to focus on one condition at a time likely silos expertise and services—and obscures critical connections across diagnostic categories.

Congratulations again Kathryn!! So happy for you! :) Can't wait to hear about all of the exciting work you'll be doing at SickKids!

Our new commentary is out now, and we think you'll agree with us! @catherinealebel.bsky.social

Visual highlighting how sociodemographic identities influence brain, behavior, and brain-behavior relationships. Figure caption: key goal of research in the brain sciences is to capture relationships between the brain and behavior. When studying these brain–behavior relationships, it is crucial to recognize that sociodemographic factors, such as sex, gender, race, ethnicity, education, religion, spirituality, health, language, environment, age and socioeconomic status (among others), can independently and interdependently influence these reciprocal associations.

Thrilled to share our latest work on the importance of considering social identities in brain imaging research, now out in @natureneuro.bsky.social.

How much is ‘enough’? Considerations for functional connectivity reliability in pediatric naturalistic fMRI functional connectivity (FC) measurements are important for robust and reproducible findings, yet pediatric functional magnetic resonance imaging (fMRI) faces unique challenges due to head motion and ...

Just a shout-out to say that the positivity of BlueSky 🦋 is so much more refreshing than the dumpster-fire that is the other place. Also, being able to curate specific feeds allows for more engagement with posts/users that you are actually interested in seeing 🧠

Middle childhood is a time of major biological change (puberty) and contextual change (elementary to middle school)--could this be an important timepoint for understanding important changes in the individual and perhaps an intervention point? Find out here: onlinelibrary.wiley.com/share/SSWWK7...

Developmental patterns of inhibition and fronto‐basal‐ganglia white matter organisation in healthy children and children with attention‐deficit/hyperactivity disorder The development of response inhibition and fronto-basal-ganglia white matter was investigated longitudinally in a sample of ADHD and non-ADHD children. Using the novel parametric race model, children....

Excited to share that my final PhD paper is out now in HBM! Here, we applied advanced cognitive modelling techniques and DWI analysis to probe the neural correlates of response inhibition development in children with and without ADHD:

So looking forward to trying out Neurodesk as an open source, end-to-end, containerised alternative to my currently messy jungle of locally installed software! This looks to be a true game changer. Congrats on the publication! 🧠💻📈
