Thinking about Angelo Mosso's brain balance method recently. There was a confound not mentioned in a 2014 review (pubmed.ncbi.nlm.nih.gov/23687118/). Blood is 1.06 X water density, but CSF will be forced out of the ventricles as CBV increases (Monro-Kellie doctrine) so net weight sensitivity is low.

Brain thermal response to low intensity focused ultrasound at the action potential level and neuron response to various stimulus pubmed.ncbi.nlm.nih.gov/40967140/

Really interesting info relevant to magnet safety: mriquestions.com/most-dangero...

Interesting approach to tissue-CSF water exchange, but someone please tell me how MT on/off difference images aren't affected by cardiac pulsatility in the perivascular spaces & lateral ventricles. How could we prove/disprove local motion effects? pubmed.ncbi.nlm.nih.gov/40950437/

For the laminauts. @layerfmri.bsky.social

Anyone ever come across a study which used a simple visible light bore camera (instead of an IR light source & camera) to assess pupil diameter during fMRI, e.g. for arousal or vigilance monitoring?

Please repost. The Centre for Functional and Metabolic Mapping is looking for a Preclinical MRI physicist (9.4T and 15.2T Bruker Advance Neo). You will join a team of 14 dedicated staff in Canada's National Ultra-high field MRI platform who also operate 3T and 7T human scanners in the same facility.

Read the whole thread. Beautiful work.

Nice work by @yoichimiyawaki.bsky.social showing the fMRI hemodynamic response contains enough info to decode stimulus type within 2sec. Happy to have helped with this project. www.biorxiv.org/content/10.1...

We’re hiring! Pls share widely: In conjunction w/ the @bowers-wbhi.bsky.social, my team is recruiting a full-time clinical research coordinator to assist with research efforts at UC Santa Barbara. 1-2 yrs experience in MRI data collection preferred. Submit apps to: recruit.ap.ucsb.edu/JPF02974

Online #fMRI course coming up August 6-8! 3-day intensive with lectures and hands-on analysis for all skill levels. #SPM, #ICA, #DataScience with @vcalhoun.bsky.social and Kent Kiehl. We love teaching this course and meeting students from all areas! Info+Reg here: sites.google.com/dartmouth.ed...

I've always wanted to explore fMRI time series as a smooth, real-time movie. Now I can with LayNii IDA. Plus, with voxel-wise correlations on the fly. Fast, intuitive, and surprisingly insightful. 40 ms TR fMRI data from @practicalfmri.bsky.social ! @layerfmri.bsky.social @afni-pt.bsky.social

One of the fun things about publishing a corrigendum is that you’ll then get loads of spam invites to conferences and special issues because they were “…truly impressed by your work titled Corrigendum to blah blah blah…” Really? I wonder what part of the incorrect sedative dose impressed them most.

We're looking for an MRI Physicist to support our (honestly, really cool and exciting) clinical trial work at our London site. Details and application at the link. Please share, tell your friends, post on other networks if you can, etc. etc. Thanks! www.linkedin.com/jobs/view/42...

Single slice EPI to visualize brain pulsations practicalfmri.blogspot.com/2025/06/sing...

If you do neuroimaging of almost any kind and you haven’t read this paper, do it. Soon. pubmed.ncbi.nlm.nih.gov/29493816/

In a sagittal view you can even see the pulsations transmitted into superior sagittal sinus. Loads of pulsation in midbrain. Note also the evident non-linearity.

So you do “physio correction” in your “de-noising” pipeline, eh? This is a single EPI slice acquired at 25 fps. Lots of dynamics just from the arterial blood pressure wave! How well does your “de-noising” really do, do you think?

Hey Elon, if you really want to get under Trump’s skin, finance Harvard for the next four years.

About to re-read after almost two decades. It showed me how little had changed in US politics since 1941. The US has always been a “drunken sailor” staggering left to right, but the bloke’s off his head today! Those on the right should consider what the next leftward lurch might look like now.

Just heard a radio announcer refer to "the new administration" and it was jarring to be reminded this thing is less than 20 weeks old. Ufff.

The 14th Cerebrovascular Research Network (CARNet) Annual Meeting will take place on November 12-14, 2025 in Fort Worth, Texas, USA (see flyer attached). We now invite you to submit your best work for a presentation at our annual meeting! Abstracts are due by July 31, 2025.

Anyone used AI to generate course material for fMRI education? If so, how did it go?

Even with the most basic bottom-up processes, attention is important. So, fMRIers, what are your participants really doing during the scans? Are you quite sure you know? And if you’re wrong, what happens to your data?
