Yesterday, @ofgulban.bsky.social gave a great talk about efficient imaging of small veins. It was inspiring. Impressive how much information is there waiting to be harvested. youtu.be/7wStzJNUXic?...

A new season of OHBM Neurosalience has started. Here's our kickoff episode where I talk with Lead Producer, Michelle Li about highlights from the past season, reaching our 100th episode, the controversial DIANA paper from last year, and what to expect. www.youtube.com/watch?v=qFcq...

We have an exciting 4-year PhD position available @maastrichtu.bsky.social focusing on intracranial EEG recordings to investigate how hippocampal ripples contribute to human memory processing. For more info: tinyurl.com/r5c49zuy (closing date Nov 2nd) Please help spread the word! #neurojobs

'In 1953, while working a hotel switchboard, a college graduate named Shea Zellweger began a journey of wonder and obsession that would eventually lead to the invention of a radically new notation for logic' @cabinetmagazine.bsky.social www.cabinetmagazine.org/issues/18/we...

One reason I developed LayNii IDA was to more easily explore my 0.35 mm multi echo human brain data. Here I’m observing blood motion artifacts across echos. The arterial signal *appear* to move across several millimeters. Best captured in short readout windows (e.g. ~3 ms readout windows in GRE).

The most primal generative experiences may be ones created by the visual cortex alone, or at least those involving the visual cortex in close collaboration with entheogenic triggers or light stimulation. Subjective Visual Phenomena – Johann Purkinje, 1819

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 more: Marshall Xu is presenting our latest updates in mapping brainstem vasculature at poster #1759, where he did some nifty image transformations + VesselBoost segmentation to get our best results yet.

Demonstrating anatomy-functional data registration of 11.7 T (!) partial-coverage human fMRI data at 0.7 × 0.7 × 0.8 mm resolution to help my colleague Alejandro Monreal-Madrigal. Who did a great work with this spiral readout acquisition. The data quality looks quite good 👏 youtu.be/Cgf8i-Lqrac

At today's layer-fMRI seminar, @ofgulban.bsky.social presented stunning high resolution vein mapping tools. It left me quite excited. youtu.be/0V8fSjo2T2w?...

New in LayNii v2.9.0: Introducing *LayNii IDA*, a high-performance tool for real-time interaction with ultra–high resolution MRI data. Built for speed, designed for discovery. Still early, but a big step toward the next era of 7T fMRI: higher resolution, larger datasets. github.com/layerfMRI/La...

In neuroimaging, we do skull stripping, but not brain stripping. Feels like favoritism.

[Field Note, Entry 05] - Refrain from repeating k-space experiment [Explosion_05]. What began as signal amplification now resembles an awakening. Frequencies folded in on themselves—revealing geometries that should not exist. - Proceeding further may breach more than spatial coherence...

The result of a large (42 authors!) collaboration: "Go Figure: Transparency in neuroscience images preserves context and clarifies interpretation" arxiv.org/abs/2504.07824 TL;DR: The FMRI world can (and should) improve results interpretation and reproducibility *today*, via transparent thresholding.

I think ultra-high field MRI will be shifting toward ~0.35 mm voxels, even in routine use. This isn't just sharper images. We now directly see cortical layers, veins... It’s a leap, not a tweak. A few already crossed this threshold, but now it's becoming practical. More: doi.org/10.1101/2025...

New layer-fMRI paper discussing an omnipresent artifact in layer-fMRI EPI data: Fuzzy Ripples. This artifact comes from short term gradient imperfections and represents the biggest limitation of layer-fMRI acquisition (wrt TRs, resolution, lower brain areas). doi.org/10.1002/mrm....

Mesoscopic veins appear as dark dots peppered across the middle gray matter surface—captured in living humans. High-precision cortex segmentation + T2*-weighted MRI at 0.35 mm isotropic resolution makes this possible. More at: doi.org/10.1101/2025...

🚨 PhD opportunity alert! 🚨 Passionate about neuroscience? Want to work with cutting-edge tech like ultra-high field MRI and intracranial EEG to study the human brain? Join us and push the boundaries of neuroscience 🧠✨ 📍 @macsbio.bsky.social 📆 2 March 🔗 tinyurl.com/bfjwpmt9 #neurojobs #PhD

The layer-fMRI field has changed since the pandemic: -> studies are larger -> majority uses 3D readouts -> a bit more sharing -> majority uses non-BOLD contrasts

Never gets old

Dr. Seiji Ogawa discovered and coined "Blood Oxygenation Level Dependent" BOLD contrast - used in almost all fMRI today. It was my great honor to interview him over two days on the very beginnings of fMRI, and so much more. www.youtube.com/watch?v=6gBK...

This was a fun discussion! talking about the unique value of layer-fMRI and how I got there. Thanks Ben for having me at the BJKS Podcast.

I had a great discussion with Vesa Kiviniemi, from Oulu University. He described his latest work using high speed whole brain acquisition (MREG) to characterize brain pulsations - and perhaps hints of the glymphatic system. podcasts.apple.com/us/podcast/n...

Rather than a typical neurosalience Podcast, we decided to post a talk I gave at OHBM on my perspective on podcasting and Neurosalience - and how I prepare for each. creators.spotify.com/pod/show/ohb...

Behold the butterfly k-space trajectory: a maddening yet elegant dance across Fourier realms, conjuring cerebral truths from the void. Gaze upon the eldritch brain patterns it summons… if you dare.

Experiments in k-space. I call this one "explosion-02".

Just a heads-up: I officially invented 'Brain Sudoku' today. You're welcome. #MRI #brainart

I am always a bit suspicious of people giving advice on social media (how to write a paper, give an interview,…). If it works for them, fine. It may not work for you. My only advice is: don’t listen to advice. Including this one, of course.

Mark you calendar for the exciting upcoming ISMRM workshop on UHF & fMRI. March 31st-April 2nd 2025, in Annapolis, MD, USA. Website (being populated): www.ismrm.org/workshops/20... Preliminary program in figure.

Mistakes were made... Accidental brain art 🎨🧠 #brainart @layerfmri.bsky.social

I see you and raise you this bubble-sorted layers 🍰

Fascinating: mesoscopic vessels remain consistently visible across different T2*-weighted acquisitions! Here’s the same living human brain imaged 6 months apart using different parameters. Which image is your favorite?

While fine-tuning 3D EPI parameters, we captured an impressively clear view of the human LGN! If you look closely, you can almost make out faint layers—wish they were more distinct though 🫤

3D EPI has come so far! Here’s a whole-brain, 0.35 mm isotropic image we recently acquired, in under 7 minutes!!! So many potential applications (and analysis challenges) ahead... 🤯

In this video, I am showing how to quickly register anatomical images onto partial coverage fMRI data using ITKSNAP: youtu.be/2txoJiLsNbU
