Because “brain network features occur in different locations across people”
Why do brain networks vary? Do these differences shape behavior? If every 🧠 is unique, how can we detect common features of brain organization?

Decoding performance (MVPA) better for OPM-MEG than SQUID-MEG 😎. The improved spatial specificity of OPM-MEG due to the reduced brain-sensor distance is key. And more sensors (beyond 40) don't improve decoding.

Not to mention the terrible effect on universities and research…
You can't have a successful economy by kowtowing to bigots who want to close the country to the rest of the world. It'd be nice if a politician had the brains or guts to point this out.
Wilful ignorance of how trade and migration actually work in a globalised economy.
The idea that the (short and long-term) movement of people -especially between India and the UK - has nothing to do with trade and investment is (obviously) wrong.

Education isn’t zero sum - why are so many in Labour @teamlabouruk.bsky.social down on universities and allow HE to be run down as if that helps those who would not go to Uni - we need to support apprenticeships and FE and HE because all are vital!
No idea what this is supposed to mean. The 50% target doesn't exist and nothing in the Gove reforms said more people had to go to university. It's a demand led system.
Burnham says he never supported the 50% university "Blair target", which became "hardwired" by Michael Gove's reforms
