Scientific publishing norms were built for a world that no longer exists. In this commentary, I argue that the future of scientific exchange may benefit from new channels of interaction and dissemination.

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.

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...

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...
