46% of preadolescent girls had "misaligned" biological sex and gender?

Hormonal milieu influences whole-brain structural dynamics across the menstrual cycle using dense sampling in multiple individuals - Nature Neuroscience Heller et al. showed dense longitudinal imaging in four females, including one with endometriosis and one using oral contraceptives, and the finding that different hormonal milieus influence widespread brain volume changes linked to progesterone or estradiol.

"no garbage"

I guess this is a different conversation but we are assuming here that score is tightly related to quality. I am less confident of this each time I sit on study section

kind of a bold claim

Factor 3: Expertise and Resources

I just got an "Additional expertise needed" because one consultant is off-site. in the year of our lord 2025. no other comments. :)

the link takes me to the wrong place! do you have another?

Why menstrual cycle irregularities belong in brain research - Nature Medicine The menstrual cycle requires tight orchestration between the brain and body, and irregularities can be both the cause and the consequence of wide-ranging health issues. Embracing this complexity, inst...

We wrote a piece for @naturemedicine.bsky.social 🧠

Menstrual cycle irregularities can be both cause and consequence of wide-ranging health issues.
Embracing this complexity could reveal novel brain–body interactions and advance neuroscience.

we are entering a whole new era of brain imaging analytics 🤩🧠

really cool!!! love to see the convergence across PET / genes / fMRI. please please consider making the .niis / statistical maps from figs 3-5 downloadable!! curious to see how closely the activation pattern you report overlaps with other CUD studies 😁

high-dose stimulants lead to psychosis -- basically, if you keep turning up the "salience" volume eventually everything seems salient and the brain scrambles to explain it?

this paper was such a joy to read. in addition to the very thorough treatment of the data I love how densely-referenced the intro is; I think I learned something from every sentence! one passing thought about the salience boost -- I wonder if that's the mechanism by which (cont)

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!

I'm curious if some journals are already implementing this. I have 1 paper under re-review and got 3 reviews. R3 was clearly written by AI, but I assumed someone got invited to review and used AI. I checked the researchsquare timeline and only 2 reviewers ever agreed.

thank you, I just dipped my toe in (louvain) and will be taking it back out. sbm = stochastic block model?

A network correspondence toolbox for quantitative evaluation of novel neuroimaging results - Nature Communications Here, the authors present the Network Correspondence Toolbox, which enables researchers to examine and report spatial correspondence between their neuroimaging results and widely used brain atlases.

It's finally here! Use the Network Correspondence Toolbox to help contextualize your neuroimaging findings 🧠

Mapping dopaminergic projections in the human brain with resting-state fMRI A functional connectivity gradient in striatum is obtained that maps onto DaT SPECT-derived dopaminergic projections and thereby likely provides a new biomarker for investigating dopaminergic (dys)fun...

super cool -- thought this might be of interest if you hadn't seen it already: elifesciences.org/articles/71846

thank you!! reassuring that this is business as usual!

Congrats, very cool finding and wow, what an effort!! I bet we could use tms + fmri to test this circuit in humans 🧐

Caio is having a good day. Another preprint on which he's first author -- this time, describing pathways through the connectome for indirectly stimulating subgenual cingulate cortex in the context of depression.

New landmark TMS trial dropped by Jonathan Downar's team, which will revolutionize care for depression even more than the SAINT trial did – extensive (10 hour!) sessions of TMS in a single day, enhanced by single dose of cycloserine. 90% response, 70% remission!

I guess I'm a little surprised by the intransigence of journals. on social media, we are all! about! high! rigor! studies! null and "boring" results are welcome as long as the study was conducted well! but those same studies get desk rejected from "high impact" journals every day.

this is the content I'm here for! when you're ~15ish applications into that streak it's hard to know if you should keep going or jump ship.

New paper out in @ScienceMagazine! In 8 studies (multiple platforms, methods, time periods) we find: misinformation evokes more outrage than trustworthy news, when it does it's shared more + ppl are less likely to read before sharing. w/ @killianmcl1 @Klonick @mollycrockett 🧵👇

sure, everyone agrees on that. easier said than done! and blaming right wing mis/disinformation overlooks that scientists have -- without those bad actors -- burned a lot of credibility via genuine bad behavior. not all scientific mistrust is misplaced, and that's a different kind of problem

not just transparency. rigor + transparency
