Thank you @avaskham.bsky.social @thetransmitter.bsky.social for covering the ongoing discussion re lesion network mapping. It is commendable when a news publication covers both sides of an issue, and a great example of unbiased and responsible reporting.

A wave of new papers discuss the merits and limitations of lesion network mapping. #neuroskyence By @avaskham.bsky.social www.thetransmitter.org/brain-imagin...

When clinicians and researchers work together toward the goal of improving lives for those with #bipolardisorder, collaboration shifts how research progresses. Hear from Tracy Young-Pearse, PhD, on BD²'s integrated approach in the latest #InvestigatorInsights. 🧠

Congratulations @shansiddiqi.bsky.social and Joe Taylor @braincircuits.bsky.social on their paper In Mol Psych demonstrating the translational power of LNM and brain circuit therapeutics. It has already changed clinical TMS practice @massgeneralbrigham.bsky.social @harvardmed.bsky.social.

New paper in Molecular Psychiatry: In patients with anxiety + depression, targeting a novel “anxiosomatic” circuit (dmPFC) outperforms standard dlPFC for anxiety—and is equally effective for depression. Free link: rdcu.be/faL22 Full link: lnkd.in/e4WZTncu But the bigger story is the pipeline 1/n

Should doctors be certified to deliver brain stimulation? @shansiddiqi.bsky.social @braincircuits.bsky.social says yes - kicking off the brain stimulation subspecialty summit (BraSS).

Many good points, one more: We empirically demonstrate that spatial bias does not contribute to real-world LNM findings when using appropriate specificity-testing: doi.org/10.64898/202...

🧠 Resting-state fMRI is often treated as the gold standard for studying the brain’s intrinsic organization. But is it actually the best way to estimate functional architecture? We tested this directly. 🧵1/8

What’s the difference between a neurological vs psychiatric disorder? @braincircuits.bsky.social , it’s only the circuit impacted. Honored to become one of the first full Professors of both Psychiatry and Neurology @harvardmed.bsky.social Excited to help bridge this divide.

We don't think it invalidates the approach. We looked into this in our data and replicated the key result showing convergence to non-specific connectome structure. However, our results also suggest there is a practical fix that is already implemented in some LNM studies. bsky.app/profile/pete...

This is a robust response. I particularly liked this figure - clarifying why the original critique showed what it did, and what was missing @foxmdphd.bsky.social

A recent @natneuro.nature.com paper analyzed lesion network mapping and raised concerns about the validity of the method. See below 👇 for our response. www.biorxiv.org/content/10.6...

A recent paper in @natureportfolio.nature.com raised concerns about the lesion network mapping method. Our team of 16 coauthors analyzed >1000 lesions and 34 symptoms and found that "The methodological foundations of lesion network mapping remain sound" www.biorxiv.org/content/10.6...

Thanks to The Transmitter for reaching out to me for comments on this methodological challenge to lesion network mapping. Scientific debate is critical to methodological advancement - so let the debate begin! www.thetransmitter.org/brain-imagin...

Are connectome-based network mapping methods and the >200 papers that have used it invalid? New paper out in @NatureNeuro says YES. nature.com/articles/s41... I have concerns about this new paper's methods and conclusions, but am biased. What do others think?

New pre-print out now from Dr Daniel Corp, @jjoutsa.bsky.social and @foxmdphd.bsky.social ‘Mapping the neuroanatomy of dystonia using causal brain lesions’ !! www.medrxiv.org/content/10.6... We map networks for the different dystonias, showing significant differences, somatotopy...and much more!!

Very interesting findings! Gliomas selectively locate within in the Action-mode Network, using glioma network mapping derived from lesion network mapping @foxmdphd.bsky.social

Check out our new work on the relationship between glioma and system-level functional networks! We identify that nearly all gliomas localize within a common brain functional network, Action-Mode Network (AMN) . biorxiv.org/content/10.64898/2026.01.05.697608v1

Excited to share that our new review, "Depression as a disease of white matter network disruption: Learning from Multiple Sclerosis," is out now in Biological Psychiatry! We propose MS as a powerful model for studying how white matter network changes contribute to depression.

What is the burden in the US of Parkinson's, Alzheimer's and other diseases? Spoiler alert: there are surges beyond the pure numbers and we need to raise awareness for the increases in both disability and burden. Parkinson disease has shown the largest growth in burden on society. cutt.ly/xtyUtS0D

Mongay-Ochoa et al. review advanced methods for mapping brain connections and identify common topographical patterns of pathology spread across different neurological disorders, including MS, AD and PD. tinyurl.com/3sz8ayup

Pruckner et al. show that the structural effects of neurosurgery extend beyond the resected tissue into connected networks through transneuronal degeneration. They were able to reliably predict these changes from preoperative MRI. tinyurl.com/a6rxvbey

Fantastic talk by Joe Taylor on the „philosophers scan“ and how imaging can help neuromodulation at the Brainclinics TMS Masterclass in Nijmegen!

Could the Parkinson’s drug levodopa prime the brain to respond better to intensive rehabilitation following a stroke or injury? Enter the idea: Let’s give dopamine pills after a stroke? Spoiler alert: This new large, randomized trial published in JAMA revealed no added benefit in recovery.

Honored to moderate a panel on noninvasive mapping of human brain circuits at MGB Neuroscience Day. Great insights from @anastasiayendiki.bsky.social @mghmartinos.bsky.social, @fredschaper.bsky.social @braincircuits.bsky.social, Alex Golby and Pravan Nanda @mgbneurosurgres.bsky.social.

Boom: The results of the ADAPT-PD personalized brain stimulation trial showed promise for treating Parkinson’s. First longer-term results for adaptive DBS in PD. Adaptive stimulation automatically adjusts in real time to a person’s brain signals. @parkinsondotorg.bsky.social

What is the update for skin biopsies to differentiate Parkinson's vs. MSA? Spoiler alert: under confocal microscope, skin biopsies look different in PD vs MSA. Donadio and colleagues describe in a new paper in Brain the uses of intraneural phosphorylated α-synuclein. @parkinsondotorg.bsky.social

In #DeepBrainStimulation the two major developments across the last decade have been 1. Adaptive DBS and 2. Connectomic DBS In a @natrevneurol.nature.com article with @julianneumann.bsky.social, we ask: Could the two be united into a common framework? www.nature.com/articles/s41... A 🧵

Can connectomic DBS go beyond where to stimulate to inform who and when? Great discussion @dbsthinktank.bsky.social with @rolstonjohn.bsky.social @julianneumann.bsky.social suggest yes! @braincircuits.bsky.social
