Doing a lit search and finding many recent papers still using the jet colormap 😭😭😭

Please don't use this colormap for anything because it's not perceptually uniform (changes of equal size don't look equal) and not friendly to people with variant colour vision.

Some alternatives below... <thread>

Really interesting paper here. Adding to increasing literature showing that interpretation of the sign of the BOLD response during task is tricky and varies across the brain - including possible reversal of neurovascular coupling in DMN regions.

This image is figure 5 from the paper showing how hallucinogenic 5HT2AR agonism alters neurovascular coupling at local and global scales.

A study in Nature Neuroscience finds psychedelics disrupt the relationship between neuronal activity and blood flow in humans and mice. This suggests fMRI results under psychedelics may reflect vascular effects as much as neural ones and should be interpreted with caution. go.nature.com/47hqVPH 🧪

Really looking forward to this. See you all there!!

If you're doing #neuroscience out there, you don't have to be peer pressured to switch from #matlab to python. You do you. ❤️

Super excited to see this published by the fabulous Natalie Rhodes. Awesome collaboration with @sickkidsto.bsky.social and @magnetokrishio.bsky.social allowed us to measure and model gamma oscillations in 100 people using OPM-MEG

[...] age-related differences in aperiodic EEG/MEG signals can be driven by cardiac rather than brain activity [...] important implications for all future research [into] aperiodic neural activity [...] control for the influence of cardiac signals is essential.

Amazing, hilarious, thought-provoking and poignant show last night in Cardiff. Thank you! Really enjoyed by all three of us (25-59). As a neuroscientist wasn’t expecting that to come up. But, sorry Angela, Friday is YELLOW…almost shouted that out…

Synaptic-dependent developmental dysconnectivity in 22q11.2 deletion syndrome Synaptic dysfunction underlies brain connectivity alterations in 22q11DS, a syndrome linked to neuropsychiatric disorders.

Excited to share the first preprint of my postdoc!
We explored a novel features space to describe M-EEG timeseries. These features are highly informative in differentiating brain states, even more than canonical features like power in predefined frequency bands! :D

New results from study of cortical thickness in 1211 psychosis cases and 734 controls demonstrates that "visual cortex is among the most profoundly affected brain regions", with effect sizes larger than prefrontal regions.

Thanks Cyril. Will feed this back to the team.

Cheers Matt!

Here’s some more details of what is included:

We are very excited to announce the open release of a new 170 participant dataset: Linked MEG, TMS, multimodal 3T MRI, 7T MRI, Connectom MRI, cognitive /questionnaire data. Immense effort from a fabulous

Amazing stuff, Sylvain. Need to find out more about how you did this.

But fundamentally I’m a fan of all MEG techniques! Please don’t cancel me OPM fans…
