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)

Great talk by Simona Schiavi at the ISMRM workshop on 40 years of diffusion! Interesting to see the DK atlas as the top choice for mapping connectomes—though, as expected, a diverse range of opinions. No single right answer!

So much research focusses on using brain connectivity to predict an individual's cognition, IQ, disease status, etc.
BUT what about the inverse problem?
Can personal data be used to build an individual's whole connectome?

TMS is delivered to the DLPFC in depression to modulate SGC activity
But axons linking DLPFC and SGC are absent.
How then does TMS stimulation delivered to the DLPFC modulate SGC activity?
Check out Caio's work on how stimulation effects propagate in the absence of direct anatomical paths
