Also, still looking for a motivated research assistant to come work with me and Yasharz at the Douglas Research Centre McGill University on our exciting post-mortem data collection and imaging project studying aging and neurodegeneration!

Great work by roqa moqadam and first preprint from the lab is out now! in collaboration Mahsa Dadar "Investigating the impact of motion in the scanner on brain age predictions" biorxiv.org/content/10.110…

We found a significant impact of motion on brain age estimation, using motion-free as well as motion-induced data from the same participants.

🎉 🎉 🎉 Congratulations to Corina Nagy and Mahsa Dadar, who were named 2022 Future Leaders in Canadian Brain Research by Brain Canada. We look forward to witnessing their future contributions to neuroscience and mental health! douglas.research.mcgill.ca/news/drs-corin…

🎉 Congratulations to @mallarchkvrty1 and Dr Marie-Claude Geoffroy, who were both admitted to the Royal Society of Canada's College of New Scholars, Artists, and Scientists for 2023!

First paper from the lab is out in Imaging Neuroscience : "Investigating the impact of motion in the scanner on brain age predictions" with roqa moqadam Mahsa Dadar direct.mit.edu/imag/article/d…

We investigated the effect of motion in T1-weighted images on brain age prediction using cortical thickness (FreeSurfer) as well as VBM, based on visual and automated ratings of the images (Euler number) and found an increase in estimated brain age in subject with higher motion

We also found that normalized Euler number closely reflects the motion in T1-weighted images and in absence of visual rating can be used as a proxy covariate for the motion signal in the age prediction model (or any other measure affected by motion, e.g. cortical thickness)

Finally I wanted to thank Nárai et al. for making the MR-ART dataset (nature.com/articles/s4159…) publicly available without which this study wouldn’t have been possible

We did a thing! Our first results from "The Douglas Bell Canada Brain Bank Post-mortem Brain Imaging Protocol" biorxiv.org/content/10.110… Yasharz Liana Guerra Jérémie Fouquet roqa moqadam Zaki Alasmar Mallar Chakravarty Douglas Research Centre
