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.

Just bone chilling. And when the imprisonment of critics is combined with his offer to enrich and immunize his loyalists, this is how democracies die fast.

But it's still our choice. Don't let him silence you.

This is a big one! A 4-year writing project over many timezones, arguing for a reimagining of the influential "core knowledge" thesis.

Led by @daweibai.bsky.social, we argue that much of our innate knowledge of the world is not "conceptual" in nature, but rather wired into perceptual processing. 👇

Screenshot of a paper abstract:

“Core knowledge” refers to a set of cognitive systems that underwrite early representations of the physical and social world, appear universally across cultures, and likely result from our genetic endowment. Although this framework is canonically considered as a hypothesis about early emerging conception — how we think and reason about the world — here we present an alternative view: that many such representations are inherently perceptual in nature. This “core perception” view explains an intriguing (and otherwise mysterious) aspect of core-knowledge processes and representations: that they also operate in adults, where they display key empirical signatures of perceptual processing. We first illustrate this overlap using recent work on “core physics”, the domain of core knowledge concerned with physical objects, representing properties such as persistence through time, cohesion, solidity, and causal interactions. We review evidence that adult vision incorporates exactly these representations of core physics, while also displaying empirical signatures of genuinely perceptual mechanisms, such as rapid and automatic operation on the basis of specific sensory inputs, informational encapsulation, and interaction with other perceptual processes. We further argue that the same pattern holds for other areas of core knowledge, including geometrical, numerical, and social domains. In light of this evidence, we conclude that many infant results appealing to precocious reasoning abilities are better explained by sophisticated perceptual mechanisms shared by infants and adults. Our core-perception view elevates the status of perception in accounting for the origins of conceptual knowledge, and generates a range of ready-to-test hypotheses in developmental psychology, vision science, and more.

The compact plainly demands ideological control of university operations by the federal government.

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.
