I really wanted to like @eLife but everything I've ever sent there, including the paper here, has been triaged by a dumb editor, stuck in the past, missing the point and maintaining the academic aristocracy. Academic publishing is crap genre fiction, not science @mbeisen

Two new preprints about physical space (geometry) and the brain. https://t.co/McLKorbNX1

Using machine learning, this study shows that self-reported experience of task states maps onto 'brain space', i.e., features of different task states identified in fMRI.

We are incredibly excited to announce a new psychedelic research collaboration with King’s College London, investigating neurobiological changes that underly the ‘mystical experience’ using high-resolution 7 Tesla fMRI scanning.

We look forward to seeing this research commence!

[Jonny Smallwood @the_mindwanders]

The good news is that we can optimise task contexts to maximise their sensitivity to specific relationships, reducing the cost of future BWAS. See work by @leechbrain @romy_lorenz to see how this could work

[Jonny Smallwood @the_mindwanders]

So the take home is that BWAS studies that use only 1 situation (often rest) require large sample sizes because any single situation may not be suited to detect brain-trait associations for all trait dimensions. See this nice review by @GrattonCaterina https://t.co/dqSc6qGCp6

[Jonny Smallwood @the_mindwanders]

Importantly we looked at how many people you would need to show the relations in the best tasks for capturing a specific trait. Our estimates suggest hundreds (not thousands) of people would be needed to show the brain-trait relationship seen in the whole sample.

[Jonny Smallwood @the_mindwanders]

These relations were clear for #gradients 3 (task positive-task negative) and 2 (vision-motor). Tasks with a strong response for one trait were different to those for other traits. This suggests there is likely no -one-size-fits-all situation for all brain-trait associations

[Jonny Smallwood @the_mindwanders]

We examined if location of any of the tasks in the state-space varied with traits using Linear Mixed Models in R. We found little evidence that traits uniformly impact on brain activity in all tasks. Instead brain-trait association were often stronger in some tasks than others 👇

[Jonny Smallwood @the_mindwanders]

To this end we took the task data from the Human Connectome Project and examined how brain activity in each situation vary with the Big-5 Personality traits. We built a 3d state-space using the first three #gradients from the work by @margulies and projected task data into it 👇

[Jonny Smallwood @the_mindwanders]

Remember back in 2022, when we didn't need to worry about a 2nd Trump Presidency, but were concerned about how many participants it would take to map links between personality & brain activity? (cf work by @smarek0502 & @ndosenbach)
We have good news 👇

Happy to share our Opinion piece @TrendsCognSci "Large-scale interactions in predictive processing: oscillatory versus transient dynamics" with @martin_a_vinck, @uran_cem, Jarrod Dowdall & Brian Rummell. Check our thread below 🧵👇

Shining a light on subcortical organization 🧠💡! Using @yetianmed's Melbourne Subcortex Atlas, here’s my latest dive into glass brain visualizations—aiming for practical and insightful anatomical renders! 🎥👇

[Nathan Anderson @rementurus]

For those in Chicago for @SfNtweets, welcome! Come check out our poster (Wed 1-5pm; I'm there at 4!). We recorded iEEG during a mental imagery task, with rsfc-MRI networks in the same patients. Come learn about changes in temporal dynamics across different functional networks!

[Lia Talozzi @lia_talozzi]

We started this journey together at the @BcBlab, and I’m so glad to see the “cognition morphospace” finally published in @NatureComms, joining the “disconnectome morphospace” in our morphospace family!
Congratulations @valepacella 👏

@CamdenCouncil And this is Keir starmers council. He's also an incompetent evil fucker

[Rob Leech @leechbrain]

@CamdenCouncil why are you so evil?

[Rob Leech @leechbrain]

£4000 bill out of no where to get paid immediately. Such incompetence. You are such evil monsters. Fuck you @CamdenCouncil
