How do we define "good" fMRI data? Especially with resting state, there are circularity risks if we evaluate data quality as showing the networks we expect to see. Javier Gonzalez-Castillo (& me & others) developed pBOLD, a new metric that uses multi-echo info.

For nearly two decades resting-state fMRI has ruled supreme. And resting-state is suprisingly powerful. But we can do so much better by using broad batteries of tasks with the right design. Here a double-punch delivered by two papers from

🧠Resting-state fMRI is often treated as the gold standard for studying the brain’s intrinsic organization. But is it actually the best way to estimate functional architecture? We tested this directly. 🧵1/8

If you teach young aspiring scientists, the new "Crash Course Scientific Thinking" on youtube is quite good. Up to episode 5 right now. Honestly, should be mandatory viewing in junior highs in the US, IMO.

I've been testing Claude to see how well it can "vibe out" a stat. power app that I've already coded completely myself - so I know what I want. It mostly gets things right with animations (those are easily verifiable) but looking into the backend stats code is nightmare inducing (see pic).

FWIW: our group collects a lot of highly-accelerated fMRI at 3T and 7T; as you know the single band reference images have a ton more contrast than the accelerated data. However, I've never once needed to use them because afni_proc does so well with alignment and blip-up/down distortion correction.
