Our study using layer fMRI to study the direction of communication between the hippocampus and cortex during perceptual predictions is finally out in Science Advances! Predicted-but-omitted shapes are represented in CA2/3 and correlate specifically with deep layers of PHC, suggesting feedback. 🧠🟦

Communication of perceptual predictions from the hippocampus to the deep layers of the parahippocampal cortex

High-resolution neuroimaging reveals stimulus-specific predictions sent from hippocampus to the neocortex during perception.

This lurid headline is about British tourists no longer getting away with overstaying in Schengen. Or being 'illegals', as it's often called in the UK.

As alarmed as people may be, they aren't alarmed enough. Trump just escalated this crisis from a fight between the federal government and a state, to a situation where one state is deploying armed forces to impose its will on another state. www.thebulwark.com/p/emergency-...

Tories to pledge to create immigration taskforce modelled on Trump’s Ice

Proposed ‘removals force’ will be tasked with deporting 150,000 people a year in bid to tackle illegal immigration The Conservatives will pledge to create a new immigration taskforce modelled on Donald Trump’s controversial Immigration and Customs Enforcement (Ice) agency, the Guardian understands. The party’s leader, Kemi Badenoch, is expected to announce the policy on Sunday as it heads into its annual conference following a year of historic low poll ratings. The proposed “removals force” will be tasked with deporting 150,000 people a year in a bid to tackle illegal immigration. Continue reading...

Really enjoyed my weekend read on 𝐚𝐜𝐭𝐢𝐯𝐞 𝐟𝐢𝐥𝐭𝐞𝐫𝐢𝐧𝐠: local recurrence amplifies natural input patterns and suppresses stray activity. This review beautifully argues that sensory cortex itself is a site of memory and prediction. Food for thought on hallucinations!

The brain is incredibly densely connected. Human cerebral cortex may have as many as *one trillion* connections.

Most of those cortical connections are recurrent, inside each area. What do they do?

Imagine an apple 🍎. Is your mental image more like a picture or more like a thought? In a new preprint led by Morgan McCarty—our lab's wonderful RA—we develop a new approach to this old cognitive science question and find that LLMs excel at tasks thought to be solvable only via visual imagery. 🧵
