Interested in the mechanisms shaping the extraordinary complexity of the connectome?
Then check out our new preprint, lead by @_francisnormand with a stellar team showing how geometry constrains connectome architecture:

💡NEW PAPER💡
Iron status markers change during youth and are linked with executive function and brain white matter. Our new work in @AJCNutrition highlights the importance of looking at iron status during the critical period of adolescence! 🧵 https://t.co/KGCbTZOlkF
Hi folks, I’m afraid it’s time for me to say goodbye. Not just leaving Twitter, but the whole show. I’ve been battling cancer last 2 years, but now only have a few days left now. Thank you wonderful people, I leave this crazy world with much love in my heart ❤️
Wow... 80% of genes are differentially expressed in living versus post-mortem prefrontal cortex tissue. Importantly implications for studying the 'living' biology of the human brain, rather than heavy reliance on what post-mortem tissue shows us. https://t.co/SJyqBZnpvp

What are good examples of the roles of subcortex in cognition, if any. What's some good literature on that?
(this is a great paper btw: https://t.co/UqqHB3oKlp)
🧠Neuroimaging peeps🧠 our field is blessed with beautiful visualizations. Our preprint provides 3 tools to help move toward code-based & replicable visualization:
📗practical guide (why should I?)
📦package selector (which one?)
🏗️code template generator (how do I start?)

Can multivariate brain-wide association studies (BWAS) only be replicable with 1000s of participants?
Our answer to this is just out in @Nature:
Multivariate BWAS can be replicable with moderate sample sizes.

Got one into neuron! LMK if you don't have access, but here's the link https://t.co/wAICL0YrNN, and I'll explain why I think we're onto something big below:
Most brain-imaging studies make 3 questionable assumptions: mental events are localizable, map uniquely to dedicated #brain circuitry, & are independent of larger context. These 19th-century views need an update. New #OpenAccess paper in @TrendsCognSci. 1/ https://t.co/97jSyxi3Dm
Brain connectomics: time for a molecular imaging perspective? | https://t.co/9DPjXHbGOg
The 1st paper of the Molecular Connectivity Working Group is out now in @TrendsCognSci!
We discuss the use of molecular imaging to advance brain connectomics, in an integrative perspective

Excellent paper indeed, w/ limitations though (for now):
9.4T,
single-slice,
small signal changes, <0.2%
& importantly: the MR sampling strategy assumes strict consistency of event-related brain responses, with no trial2trial variability.
