Are connectome-based network mapping methods and the >200 papers that have used it invalid?
New paper out in
@NatureNeuro
says YES. nature.com/articles/s41...
I have concerns about this new paper's methods and conclusions, but am biased. What do others think?
If you are planning to go to OHBM 2026 this year, consider attending the pre-conf Brain Connectivity Workshop, celebrating our 25th year! @ohbmofficial.bsky.social

My paper reviewing how different neurodegenerative diseases affect autonomic function was just published.
Our cover is now live at Nature Neuroscience @natureneuro.bsky.social !
Absolutely incredible work by Davide Momi, John Griffiths,and a stellar team of neuroscientists with a multidimensional view of brain dynamics.
This work gives us a WHOLE BRAIN map of excitability.

Happy to share that our article “Human lifespan changes in the brain’s functional connectome” is now published online at Nature Neuroscience @natureneuro.bsky.social !
Many thanks to all collaborators & data contributors, and the editor team & reviewers!

When we use TMS to treat depression, we think it alters neural activity in a deep brain structure known as the subgenual anterior cingulate (sgACC). But this is hard to test directly, until our preprint with @coreykeller.bsky.social, @neuro-engineer.bsky.social, Nick Trapp, and Aaron Boes (UIowa) 1/

📢 Exciting news! OHBM is partnering with United Airlines for our upcoming event. Enjoy special rates on flights to Brisbane, Australia, from June 21 to July 1, 2025. For more information, visit the link in comments! #OHBM2025 #TravelwithUnited
June 2025 is an exciting month for Psychological and Brain Sciences in Australia! In addition to our joint meeting between EPC and APCV, the Organisation for Human Brain Mapping meets in Brisbane the following week. See below for a schedule of events linked with OHBM.
How is the body experienced in mental health conditions? 🧠🫀🫁
Our (@gabmackie.bsky.social) new paper in eClinicalMedicine explores lived experiences and patient priorities for interoception research. 🧵1/n

A figure depicting responses to the question “How are body signals related to your mental health”, including both themes and example quotes. Broad themes included: (1) location of bodily sensations; (2) when sensations occur; (3) psychological symptoms and factors; (4) intensity and frequency of sensations, and (5) lifestyle factors.
Workshop contributors had a variety of initial thoughts in response to the question: “how are bodily signals related to your mental health?” This was conducted prior to any detailed information about the aims of the workshop, or the field's perceived notions of interoception. 🧵4/n

Important point Andy. But volumetric data might not be as close to the real data as we think and is also based on models. E.g. we sample data on a square grid, even though the MRI point spread function is not a square.

Ever heard of EEG microstates? Usually defined as cluster centres of topography, the dynamics of MS sequences are referred to as "syntaxes". Our new review discusses syntax methods and show how they could be better associated with the underlying EEG signal: 🧵👇 www.sciencedirect.com/science/arti...

For data defined on top of a graph/network (e.g. annotations on brain graphs), it is efficient to decompose them with filters that adapt to the spectral characteristics of the data at hand | w. @dimitrivdv.bsky.social @rikossenkoppele.bsky.social + C-F Westin
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?
YES - with AI:

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?

Can damage to a specific brain circuit cause psychosis? New paper out today by @andrewpines.bsky.social @shansiddiqi.bsky.social says Yes! Hub of the circuit is in the hippocampus - great alignment with NMDA encephalitis. @braincircuits.bsky.social

Big news: there are all sorts of different synapse types in the brain 👀‼️⤵️
9/ 🚨 But there’s more!
SNM reveals the heterogeneity in cortical atrophy among AD patients. AD patients are not only different from healthy individuals but also highly diverse among themselves, beyond the conventional findings of group/subtype-level studies.
