I'm so excited to share the culmination of this thrilling adventure with @DrAmyJanes and @blaisefrederick, out now in @NatureHumBehav
📜 includes tools to detect and remove this pernicious 🎈artifact that hides in plain sight in our #fMRI datasets

🧵..
Korponay et al. show that estimates of functional brain connectivity artifactually inflate over the course of resting-state and task-based fMRI scans.

Do you use fslmaths for image processing? In our latest publication, Rorden et al. introduce niimath, a clone that offers performance optimization, improved portability, and open licensing doi.org/10.52294/001c.94384 @OHBM @fMRI_today @mallarchkrvrty1

Can we get 500 retweets on this? If you watch one thing today make is this and pass it on

Do you have sometime brain MRIs with weird orientations? You can quickly reorient them online with our tool neuroanatomy.github.io/reori… !

I hear you. Violence toward children & animals are my Achilles heel…& I’m pretty tough overall.
I can’t imagine the horror & suffering of the survivors.

When COVID-19 surfaced in 2020, the medical field missed something, and it cost lives.
Airborne viruses can travel much further than originally thought. To curb infection, we should have focused on indoor air systems. @DrLaPook reports, Sunday. 60Minutes.com
If you are interested in helping follow up on findings like this, I’m looking for a postdoc (T32 supported. US citizen or green card needed).
Check it out! @CKorponay just uploaded a preprint of our new paper with @DrAmyJanes. This is a really intriguing finding that seems to have been hiding in plain sight in pretty much every dataset we’ve looked at so far… @McLeanHospital @NIDAnews #noiseassignal 1/
Cole gives a great, detailed breakdown of the paper.

We found an fMRI issue and a fix!
: functional connectivity throughout the brain artifactually inflates during the course of fMRI scans - by an average of more than 70% in 15 minutes of scan time - producing both spatial and temporal distortion of brain connectivity maps.

Low frequency physiological noise increases over time within and between fMRI scans. This is a real problem for connectivity measurements (especially dynamic ones!) if you don’t deal with it. Fortunately, we found that you can efficiently detect and remove it. 2/
rapidtide detects and removes this noise very effectively (in addition to all the other cool things it does!). You can go get it here for the low, low price of free. github.com/bbfrederick/rapid… (github.com/bbfrederick/rapid…)

As fun as it is watching the Musk/Twitter meltdown in real time, I have a nagging worry that 10 years from now, as Musk drops one asteroid after another on a ruined Earth from his Mars base, we’ll realize we were there for his supervillain origin story.
