That feeling when you make your model super efficient it can not only fit much bigger that, but runs faster at the same time! 😎

Breath hold fMRI is great for measuring CVR... *except when your participant or patient doesn't quite perform the task the way you'd like. Let's see if we can fix that! (Spoiler, it looks like we can, using the respiratory belt data to predict or fill in missing PETCO2 data!)

True, but you would still need a ground truth to learn from, right? I’m more than happy to discuss ideas in this topic.

Research would become boring if we could do that 😜

010

Yes, I meant we don’t really know the ground truth… Plus, the HRF differs across different regions of the brain and possibly across the population. A very interesting but hard problem to solve! With our algorithms we always saw that assuming the shape was good enough for most cases 🤷‍♂️

Eneko Uruñuela @enekourunuela.com · 24/04/2025

How would you learn the HRF from the data when the ground truth doesn’t exist? Even if you were to transfer learn from task fMRI data, the model would be quite biased when applied to rest…

The single echo is also available in AFNI as 3dPFM. I would suggest using pySPFM with stability selection for better results though.

Eneko Uruñuela @enekourunuela.com · 22/04/2025

We showed that with our multi-echo multivariate paradigm free mapping approach we could get fairly close to GLM activity maps in task fMRI data. Stability selection (not multi-echo dependent) really helped us get robust results. www.sciencedirect.com/science/arti...

Whole-brain multivariate hemodynamic deconvolution for functional MRI with stability selection

Conventionally, analysis of functional MRI (fMRI) data relies on available information about the experimental paradigm to establish hypothesized model…

I did something similar to see my post stars a couple of months ago. Such a fun application!

I don’t know where they store the data, but I will ask around!

Eneko Uruñuela @enekourunuela.com · 20/03/2025

They may have US funding but it is a nordic company and afaik very few in the team work from the US…

At least it’s not full of Pokemon 🤣

That would be great. I miss seeing different setups now I’m only on this site

I think they’re still good to get ideas ☺️

There aren’t many of us here just yet. Here’s a feed to catch the little Tana talk that happens at the moment: bsky.app/profile/did:...

Eneko Uruñuela @enekourunuela.com · 05/03/2025

I love Tana. Would 100% recommend. The AI features can be incredibly useful if you set them correctly. Happy to help as well!

DM me your email and I'll forward the info ;)
