1/🧵 Research on ADHD neurobiology has made leaps, yet remains elusive. Dive into our latest paper in @NatRevNeurosci as we examine progress, tackle past hurdles & explore emerging frameworks to unlock ADHD’s complex neurobiological underpinnings. twtr.to/3gOgE
I didn't tweet all the findings, but @bart_larsen gave a beautiful talk on E/I balance and the brain, using pharmacological-fMRI and cutting edge computational modeling... My mind is still spinning @FluxSociety #flux #flux2024 (especially this paper pnas.org/doi/full/10.10…!)

Very happy with how this one turned out! This started as a curiosity, that built into a side project, and eventually into a very cool paper! This was also super fun to work on with @ArielleKeller! Check out her thread below and the preprint here: osf.io/preprints/ps...
☀️ New preprint! ☀️ Cognitive tests from 23,000+ participants in 4 datasets show cyclical fluctuations across the calendar year, including a small but replicable “summer slide” where youth show worst performance after school vacation. t.ly/OMzgl thread below! 👇 /1
Important paper for anyone who does group comparisons (based on age, or anything else) in fMRI. Suggests that some group/age effects in fMRI might be vascular rather than neural? onlinelibrary.wiley.com/doi/full/10.10…
“What happens in November determines whether this line of research continues or whether we are up against the strongest headwinds ever," says @emilyjacobs.
The U.S. election will make or break efforts to refocus medical research to make it more accurate for women. “It’s either going to enter its heyday or it’s going to be gutted,” says neuroscientist Emily Jacobs. @maggiemfox for @FullerProject & @MsMagazine bit.ly/3YycRhe
Check out this article that spotlights on the truly incredible work that @HellerCarina has done to understand how the brain changes over the menstrual cycle and on oral contraceptives! Congrats @HellerCarina! We are so happy you joined the lab to continue this work!
Exciting news!🎉 A big thank you to @maxdkozlov for covering the research I have been pursuing over the past few years! The article is incredibly well-written and captures the essence of our work. 🤩🙌 #WomensHealth
On the road to Minneapolis, excited to dig into reward & brain tissue iron in a post-doc with @bart_larsen at @UMN_MIDB!!!
Ever wondered if the *dynamic* organization of brain networks is conserved across mammals? We too! Our latest work @NatureComm details what we found by comparing fMRI patterns in humans👨macaques 🐒 and mice🐁 nature.com/articles/s4146… Mini 🧵 @IITalk
Likely a technique that is going to change dMRI arxiv.org/abs/2409.07375 My two cents: 1. Performance on high-b and high-field scanners is the key (not shown in the work) 2. No need for TOPUP/EDDY in the future. by @berkin_bilgic @Yogi_Spoke @nastasiayendiki @SusieHuangMDPhD
When I think about the status of women’s health it’s easy to get angry. But there is so much to be hopeful about. Follow @Bowers_WBHI for updates on our new initiative to advance women's brain health through deeply collaborative science. We need all of you behind this. 💫
Women's health can't wait. So take a look, join us, and then let's get to work. 👇🏽 youtu.be/tX5uczeISOQ?si…
"The need for #iron especially increases during pregnancy, when people are even more vulnerable to anemia," #MIDB Co-Director Dr. Michael Georgieff tells @TheAtlantic theatlantic.com/health/archive… @UMNPeds | #irondeficiency | #pregnancy | #anemia
Planning to host an online DSI Studio workshop. Looking for suggestions on key features or applications to cover. Any suggestions?
My lab, part of @UMN_MIDB, is a hiring a senior coordinator/lab manager! Ideal candidate will have experience managing research and an interest in precision brain imaging + clinical trial research. R/t share! D/m, email with questions. Job id: 362340 hr.myu.umn.edu/psc/hrprd/EMPL…
This is now out in Biochemical and Biophysical Research Communications (@BBRCME)!! 🥳 sciencedirect.com/science/articl…
The brain is a physical computer, so it cares about the same things that our laptops do: energy, space, and material. What lies between computational dynamics and biophysical constraints in neural networks? A perspective with @LindenParkes @bart_larsen arxiv.org/abs/2311.15572
Huge congratulations to my dear friend @AshCParr for her awesome talk at #OHBM2024 on brain-iron development and mechanisms of critical period plasticity! H/t our fellow @LNCD_Pitt alum @bart_larsen for co-chairing the session!
We will be hosting an awesome symposium at #OHBM2024 on studies of the role brain iron in cognition, health, and brain function across the lifespan! Check it out Thursday at 9am!

Absolutely phenomenal work by @valerieJsydnor! From the creation of a curated thalamus tractography atlas, to identifying devel. and environmental effects, to replicating across three datasets, and integrating with other neurobio measures, the contributions are many!!

Out now in PNAS! Check out our work using biophysical modeling of the E/I ratio to provide evidence that E/I decreases in the human brain during adolescence and supports cognitive ability! Work co-led by me and @ZShaoshi with @sattertt @bttyeo.
Milestone achieved! Our paper on biophysical modelling and E/I ratio estimation is now out on PNAS! pnas.org/doi/10.1073/pn… Check out our short summary on Kudos link.growkudos.com/1e9chg5dekgand and the thread below 🧵👇 @bart_larsen @valerieJsydnor @sattertt @bttyeo
