Interesting how companies and the financial world is racing to spend mindboggling amounts of money to build the infrastructure to train computers. But we are leaving the infrastructure to train and educate humans crumbling. The question is who will train who?

This is a disaster if the EU doesn't follow up by doubling the budget 😬🧪

There's a very cool Buzsaki #neuroskyence paper out in Science this week, looking at hippocampal spatial information encoding by multiple interneuron subtypes in parallel. The brilliant @agonru.bsky.social and I wrote a wee perspective to go alongside it: www.science.org/doi/10.1126/...
Do inhibitory interneurons encode information or just keep the rhythm?
Inhibitory interneurons may help encode the brain’s internal representation of space
