it is - but now you also have a pair of Bluetooth headphones that can take phone calls! I still take mine out sometimes, but stick with it - you’ll find you’re less tired in the evening from active listening all day

Definitely had a few, but not quite that many all at once. Block and report them

This is such cool work Hunter - by any chance did you look at whether the participants had prosthetics?

Fantastic - please add me!

Mostly looking at language loss with dementia progression & new ways of assessing that carefully. Lots of implications for how we should measure language and cognition in the presence of cognitive decline before making inferences about cognitive reserve though!

Forgot to tag @marcocalabria.bsky.social - and it appears Boon Lead Tee is not on Bluesky

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.

This is a great initiative @nirx-nirs.bsky.social - do you do something similar?

John Anderson 🇨🇦 @janderz8.bsky.social · Jul 21

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

Maybe this is what print newspapers and letter mail needs to recover…

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

The Royal Society is offering £4 million per researcher for scientists in the USA who want to move to the UK. The money offered is £30 million in all for all the Fellowships. These Faraday Fellowships are for 5 to 10 years.

To any international #U.S. bound students who may have had their lives upturned by recent events, please consider #Carleton, consider #Canada. I am open to applications from graduate students #academia.

Looks very cool, would also be useful for studying older adults

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.

Original plotting was with easytopo, but it’s easy enough to replot using surfice.

Easytopo outputs for a two-back minus one-back contrast.

Great to see some of the lab’s first #fNIRS data come through (this is HbO2 for a 2-Back -1-Back contrast)

Saw this quotation the other day & it resonates “You need to be brave enough to be bad at something new.” I may pin this one to my office door

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!
