🚨 New preprint: Objective Quality Assessment for Precision fMRI
Precision functional mapping (PFM) enables individual-level brain network studies — but demands more, and better, data.
We introduce an objective framework to determine when a dataset truly supports interpretable, replicable PFM.
Such a fascinating paper! Less than 3 years after the discovery of the new motor network (SCAN) interleaved between effector motor regions, SCAN is proving highly relevant for Parkinson’s! It offers potential to improve treatment and reduce symptoms non-invasively.

Non-invasive brain surface stimulation targeting personalized SCAN alleviated symptoms in patients with Parkinson’s disease. See the videos below.(www.nature.com/articles/s41...)
Happy to share a short but super cool video that gives a quick overview of our Nature paper on the somato-cognitive action of netwokr in Parkinson's disease

I’m very excited about this new work describing the specific cortical-striatal circuits that are altered in Parkinson’s Disease and that should be targeted for optimal PD treatment.

Parkinson's disease affects over 10 million people worldwide. A new study led by WashU Medicine researchers is paving the way for more personalized, non-invasive treatment, tackling this neurological disorder at its root. @ndosenbach.bsky.social medicine.washu.edu/news/brain-n...
A recently discovered brain network that links cognition (thinking) and actions may have an important role in Parkinson’s disease and could improve its treatment, according to a study published in Nature: spklr.io/63320DMwOi

What if we've misunderstood how ADHD stimulants work? WashU Medicine brain imaging and child neurology teams joined forces to uncover where in the brain these drugs act — knowledge that could improve how attention disorders are treated. medicine.washu.edu/news/stimula...
Things are not obvious. And I have so many new questions now.
Envie de créer un kit d'enseignement des neurosciences pour mieux apprendre à destination des lycéens ?
Un énorme projet (1 an sur le nouveau design et 3-4 ans sur les vidéos tuto !) 😱
Rendez vous lundi soir !

Important consideration to better model neuroimaging data
That's going to be very useful !!

Mike felt joy for the first time in decades after we turned on his new brain pacemaker or PACE

This new Yeo Lab tool should immediately and permanently replace sample-size-only power calculations for functional MRI.

We have argued that the brain’s Action Mode Network controls functions required for goal-directed behavior. www.nature.com/articles/s41...
Now, in new work, we show that AMN contains distinct subnetworks for making decisions, implementing actions, and processing feedback. doi.org/10.1073/pnas...
Looking forward to talk about my latest research findings at the LOOPS webinar

“An Action Networks Model for Pain”
We propose a new model for chronic pain — and highlight two functionally connected cortical networks that could revolutionize how we treat it.

@roselynechauvin.bsky.social & team use daily fMRI to show that 2 weeks of arm disuse triggers spontaneous “disuse pulses” and boosts connectivity in motor cortex, thalamus and putamen.

My med school textbook says stimulants like Ritalin treat hyperactivity by “stimulating” the brain’s attention and cognitive control systems. We studied children taking stimulants in the ABCD Study, and the largest differences were actually in arousal and reward networks! Check out our preprint!
Had a great time speaking with Sydney about our most recent paper out now in @natcomms.nature.com @macwoodburn.bsky.social . Paper link here: rdcu.be/ehbOy
Happy to read @sydneywyatt.bsky.social’s piece on the recent study by @samkrimmelneuro.bsky.social
@ndosenbach.bsky.social @gordonneuro.bsky.social re: the human red nucleus
I was glad to discuss this great work with Sydney
