These results are exciting because they show how fMRI BOLD, despite being a noisy signal, encapsulates spatially heterogeneous, multifactorial and multimodal properties of brain organisation through its temporal variability.

Together, this work shows that BOLD signal variability preserves neurobiological precision, enabling more targeted questions across age, behaviour, disease, and supporting its use in computational modelling and multimodal, systems-level neuroscience!

We looked at both local (i.e., regional) and global (i.e., inter-regional) BOLD signal variability measures in different fMRI datasets that differed in their acquisition protocol (given the impact this has on many fMRI parameters, mostly spatial and temporal resolutions).

There's a lot in there but the crux of the paper lies in how, in both datasets, BOLD signal variability traced histology, microstructure, transcriptomics, neurotransmitter receptors, metabolism, fMRI static connectivity, and empirical and simulated MEG data.

I once saw a (very interesting) talk about sleep in which the speaker started by saying that we don't really know how to define sleep, and then proceeded to operationalize sleep in flies as basically periods when they are still for a long time. This got me thinking...

Biologist folk (especially in evolutionary biology and/or ecology, but it donโ€™t matter): Can you give me your favorite examples of trade offs in biology? Organism or system donโ€™t matter. Primary literature or reviews preferred.

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary ๐Ÿง  www.nature.com/articles/s41...

I wish I could carry the enthusiasm for science from this conversation with me in a cup. Fascinating and contagious!

I recently had the great pleasure of interviewing Michael Bruchas about an absolutely banger recent paper from his group that tracked down cells in the brainstem that subtlety and precisely control the output of the locus coeruleus. Check out my interview here. I hope you like it as much as I did!

Completely agree w/ everything @avramholmes.bsky.social lays out here. fMRI has a big role to play in helping link across scales of measurement, neural organisation and species. But for that to work, we need to incentivise the growth and development of scientists that can translate across domains.

Important work on the caveats of working with surface MRI data: a step closer to disentangling artificial vs biological sources of spatial autocorrelation. To add, these considerations are also essential for those working on MRI dynamics: space <โ€”> time are intertwined concepts. Way to go Jayson! ๐Ÿ˜Š

Jayson Jeganathan@jaysonjeg.bsky.social

Do you work on surface MRI such as HCP data? Our paper is finally out in Imaging Neuroscience, showing biases in surface fMRI. The revised ms has many new insights! TLDR: Vertices are much closer to each other in sulci, resulting in (fake) high spatial autocorrelation. (1/5)
