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.

Happy to see this out: our new preprint shows that laminar GE-BOLD fMRI decoding isn’t immune to vascular draining biases. Simulations reveal false positives due to multivariate signal spread across layers, but oversampling + deconvolution can (sometimes) improve specificity.
