Can a brain injury make someone lose their imagination?
We describe rare cases of acquired aphantasia, people who lost the ability to visually imagine after a stroke or other brain injury. Now published in Cortex 🧠 @braincircuits.bsky.social

Agreed! Which is why choosing appropriate control cohorts and comparison groups is such an important step to do before declaring that any finding a specific to your “syndrome/symptom” of interest.
8️⃣ Shout-out to our first author Juliana Wall, whose outstanding work brings clarity and rigor to complex neuroimaging data! 👏
9️⃣ We’re grateful to our colleagues, the many patients we partner with, and the Child Neurology Society community—advancing research together to develop new therapies!
7️⃣ So what’s next?
We're looking for clues in how stimulant medications used in ADHD alter brain networks in individual patients to generate new focused neuromodulatory therapies!
6️⃣ Yet, amidst uncertainty, the Anterior Cingulate Cortex (ACC) robustly stood out as a region implicated beyond chance and converging with parallel evidence of anatomical changes. This may hint at a critical neural target.
5️⃣ BUT—crucially—our analyses also found this network pattern was similar to that seen across psychiatric disorders, and that these patterns are similar to what you’d see with randomly chosen brain coordinates!
Meaning: Caution is needed before concluding specificity in coordinate mapping studies.
4️⃣ Indeed, we found scattered locations consistently mapped onto brain networks associated with reward processing and cognitive control (Cingulo-Opercular network).
3️⃣ Using Coordinate Network Mapping, we asked a new question: could these scattered brain locations converge on common brain networks—even if exact coordinates differ?
2️⃣ Why this study?
Do brain imaging studies on anatomical changes in ADHD consistently identify the same brain regions? Surprisingly, our meta-analysis of 38 studies found minimal spatial agreement across studies.
Thrilled our ADHD network mapping work is now out in Annals of the Child Neurology Society, and honored to be featured on the cover!

Aligning Research to Impact Autism (ARIA) aims to speed up the route from basic research to treatments for profound autism. Scientific director Matthew State shared more about the initiative’s goals and upcoming RFAs in a Q&A with @lauschenk.bsky.social.

Reduced function or injury to the frontal pole may increase creativity by disengaging the self-monitoring & cognitive control actions of the frontal pole to allow novelty seeking & creativity to be unleashed. @braincircuits.bsky.social @foxmdphd.bsky.social @julianneumann.bsky.social
How can a brain disease increase creativity? We derive a brain circuit from creative tasks demonstrating they share reduced activity in the right frontal pole. Then we show that brain lesions & neurodegeneration that increase creativity are connected to this location

Great article on how methods ALWAYS frame the question more than you think…
🗣️ Language is widely distributed throughout the brain 🧠
In a recent correspondence in @natrevneurosci.bsky.social, we suggest that there is no 'language network' in the brain. What appears as such is an inevitable illusion created in part by the methods we use.

Excellent resource!!!
I would have titled this: “Shining a light on the black hole: Look you can see activations in orbitofrontal cortex now!”
Completely agree.
This is wild! What a cool idea and set of approaches.

I think there is a way to do exploratory research very rigorously. Just use full transparency. Publish the entire github history for the analysis chain, nits, zits, and all. And of course, focus more on the strength of evidence than posthoc narrative building.
The work incorporating optimisation to guide experiment design/analysis is also a way to do rigorous exploratory research. E.g.,

Students don't need a perfect teacher. Students need a happy teacher, who's gonna make them excited to come to school and grow a love for learning.
Great book!
Recruiting diverse talent is insufficient; we need retention. And we can do better.
Here’s hoping this highly practical paper is helping guide change in academia.
