Very cool - and useful for generating predictions/simulations based on pilot data (if you think the pilot data is representative)

Fantastic #AAIC session on Language as a Lens chaired by Dr. Marco Calabria and Dr. Boon Lead Tee. This was such an exciting session & I love the integration of new technology and tools for assessing language and its relation to dementia and cognition.

I wonder if #AI will close academic discourse even further as people mistrust people they don’t already know. We were already being flooded with papers pre-A.I., now we need a way to verify quality in an era when the internet is being hit with a tsunami of content. #academia

Would it be possible to have ONE sign on for all journals? It would be absolutely glorious to have a single place to submit, track your review assignments etc. Going through the dance of what's your password for Elsevier/Cambridge/Sage etc journal X, reset, login every time is getting old. #academia

Integrating SAMER Retrospective Motion Correction into 3D Deep Learning Image Reconstruction for High-Quality, Fast, and Robust Brain MRI by Daniel Polak (Siemens Healthineers, Erlangen, Germany), et al. Patient motion is one of the most common sources of image degradation in clinical neuroimaging, manifesting as blurring, ringing, or in severe cases ghosting/folding artifacts. Radiologists are often forced to either interpret images despite these artifacts – risking missed or misinterpreted pathologies – or to request costly and time-consuming repeat scans. In pediatric patients, motion is typically more severe, often necessitating anesthesia, which increases both procedural risks and costs. Motion artifacts also reduce the reliability of automated quantitative clinical tools, such as those used for brain morphometry and the identification or segmentation of hemorrhages, edema, and tumors. Such tools are increasingly important in the screening, monitoring, and treatment of neurodegenerative diseases such as Alzheimer’s. Scout Accelerated Motion Estimation and Reduction (SAMER) is a retrospective motion correction technique for brain imaging that enables fast motion estimation and artifact correction without the need for external tracking hardware. Clinically evaluated in both adult and pediatric patient populations, SAMER has significantly reduced the number of non-diagnostic motion cases. More recently, SAMER has been integrated into a deep learning-based image reconstruction framework to support highly accelerated, motion-robust 3D brain imaging. In this article, the authors review the combined DL-SAMER technique and demonstrate its effectiveness in vivo using MPRAGE and SPACE acquisitions at R = 6 acceleration.

Every year I get to write an annual report. Inevitably I start tackling this only grudgingly, but then, as I start to fill this out, I see the incredible work the team has accomplished over the past year which is humbling and inspiring. This year was great, I can’t wait for next year!

🧠 New preprint alert!
@carleton-cogsci.bsky.social PhD student Salah Aziz and our fantastic team tracked hippocampal changes over time in >1,300 individuals using surface-based morphometry (SBM).
Here's what we found—and why it matters for Alzheimer’s research 🧵

🚨New Preprint Alert!🚨
We just dropped a new paper on medRxiv that uses machine learning to rethink how we diagnose cognitive decline — and the results are 🔥.
Let’s talk about brain data, hidden clusters, and how we might catch dementia before it’s diagnosed.

📢 Join us this Wednesday, April 2, 15:00-16:00EST to learn about "Multilingualism at the intersection of psychology, neuroscience, & education" with Dr. Gigi Luk

Everyone is welcome! Join on campus (DT2203) and via Zoom carleton-ca.zoom.us/j/94196446262
promo Multilingualism is an interactional experience between an individual and her environment through multiple languages. Research in multilingualism involves multiple disciplines. In this presentation, I will present an overview of my research program in psychology, neuroscience, and education focusing on the development and learning aspects intersecting with multilingualism. I consider development as an ambient process in response to the environment, whereas learning being an active process involving explicit instructions. These two processes were not mutually exclusive and should be considered when examining multilingualism. Finally, I will share how research in multilingualism can benefit from a transdisciplinary perspective by integrating ecologically grounded questions and laboratory-based research approaches. Gigi Luk obtained her Ph.D. in Cognitive Psychology from York University, Canada. She then completed a postdoctoral fellowship at the Rotman Research Institute at the Baycrest Center before joining the Harvard Graduate School of Education. In January 2019, she joined the Department of Educational and Counselling Psychology at McGill University where she is currently a full professor. Luk’s research on the cognitive and neural consequences of multilingualism extends across the lifespan. She leads a research program that examines how diverse language experiences shape development and learning using neuroimaging methods, behavioral methods, and educational data. Her research has received funding from agencies in Canada and the U.S. She has served as associate editor for Bilingualism: Language and Cognition and is currently an associate editor for Child Development.
