Carne asada (y vegetales) del laboratorio

Very happy to host Dr. Flavia Venetucci from @sickkidsto.bsky.social last month and to the start of a great collaboration.

Can't ask for a better team #ISAR2025

La investigación de mi alumna @aleloc.bsky.social y del laboratorio: www.jornada.com.mx/noticia/2025...

🚨Preprint!🚨 So excited to share my 1st major study as a postdoc at @holmeslab-bhi.bsky.social!🤘 www.biorxiv.org/content/10.1... Using a transdiagnostic framework, we found that brain network dynamics were able to discriminate individualized psychiatric symptom profiles with high accuracy 🧵1/9👇

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

**FMRI/neuroimaging folks** Quick reminder @ the next AFNI Bootcamp: May 28-30, 2025. Learn through interactive data analysis! Day 1-2: data viz, single subject analysis and QC. Day 3: statistics, results reporting and group analysis. Details, registration and schedule: afni.nimh.nih.gov/bootcamp

Registrations are open for the 2nd International Symposium on Addiction Research (ISAR) 2025 in Querétaro, Mexico, from August 25-27. Come visit us and show your work! addictions.inb.unam.mx

PhD student from my lab, @dangeles.bsky.social just released our collaboration with @mariejosevantol.bsky.social . "First vs recurrent episode symptomatology in Major Depressive Disorder and its relation to brain function and structure: a network approach"

Awesome @afni-pt.bsky.social invited me to this and I think it's a great concept.

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

7 years ago, I received funding for a project on personality, incentivized prosocial behavior & social status in groups. Today, we've made the anonymized data publicly available. Researchers can now use it by citing the preprint/paper (no need to add anyone as a coauthor): doi.org/10.31234/osf...

People from my lab did a wonderful job on Brain Week teaching about the problems with substance use. A major effort on their part.

Beyond Mechanism—Extending Our Concepts of Causation in Neuroscience onlinelibrary.wiley.com/doi/10.1111/... - really pleased that this paper with Henry Potter is now published in the European Journal of Neuroscience 😊

New preprint from the lab: www.biorxiv.org/content/10.1... This was led by former Bachelor student Débora Elizarrarás and postdoc César Carranza. Here we wanted to study structural brain changes in opiod self-administration. Specifically if there was a link between MRI volume and neuroinflamation.

Scientists are called on more and more to respond to questions about their results. We tried to put down some ideas for the best ways to do that based on our years of observing these interactions. Engaging is better than not, especially when science is under attack. www.science.org/doi/10.1126/...

🚀 We’re officially on Bluesky! 💙 The Women in Network Science (WiNS) Society connects and supports network scientists who identify as underrepresented genders in the field. Follow us for updates on events, opportunities, and exciting research from our community! #NetworkScience #WiNS

Hey neuroscientists: were you, your lab or any of your ongoing projects caught up in any of the latest NIH firings? You can find me on Signal at avaskham.54 if you want to chat. 🧪 #neuroskyence

New paper led by Aurelie Bussy now out in Neurobiology of Ageing Here we use non-negative matrix decomposition using morphological and qMRI measures (T1, T2*) to understand the relationship between GM and microstructure across the Alzheimer's spectrum. www.sciencedirect.com/science/arti...

New work let by PhD student at the lab @jalilrt.bsky.social . Does chronic stress increases alcohol drinking in adolescent rats and how does that affect their behavior, brain structure and functional connectivity, and is there an effect of sex? www.biorxiv.org/content/10.1...

This is so cool!

We are organizing a Neuroimaging Summer School with the @cervo-ulaval.bsky.social in Quebec and @ibroorg.bsky.social. LATAM graduate students will have all expenses paid. More info at the site and here [email protected] Calls will close April 20. q2summerschool.com ibro.org/training-opp...

It’s out! 🎉 Check our paper “Disentangling the effect of sex from brain size on brain organization and cognitive functioning” 🧠, where we explored sex differences in the brain while removing the effect of brain size differences. 1/10 link.springer.com/article/10.1...

In biomedical sciences, there is a gap in understanding how sociodemographic factors affect biological and behavioral processes, in part due to inconsistent data collection. To address this, we're surveying researchers about their sociodemographic questionnaires: forms.gle/T8EiWHNJ4UoS...

ECT, TMS, and ketamine outperform other options for treatment resistant depression. Should we be offering these options to patients earlier in the course of illness? www.nature.com/articles/s41...

I was today years old when I found out that famous labs average multiple trials/blocks of fMRI data before running multiple linear regression/GLM 🤯 This breaks so many principles of statistics that one could write an entire book...

Maybe slightly odd timing, but we'd like to announce: A new AFNI Bootcamp for FMRI/MRI, Jan 29-31, 2025. This part will focus on group analysis, statistics, surface analyses, results reporting and more. This event will be virtual. Please see here: discuss.afni.nimh.nih.gov/t/afni-bootc...

New collab paper with my former PhD student Said Jimenez. in BPD, we found a remarkable interrelationship between three of the core nodes of the disorder: 1) feelings of emptiness, 2) identity instability (identity diffusion), and 3) anger dysregulation. www.sciencedirect.com/science/arti...
