Quite impressed with the results reported here, a cerebellar learning signal affects neocortex plasticity. In the context of credit assignment, this suggest a cross-system coordination of plasticity: elifesciences.org/articles/109...

I recommend this school to anyone interested in computation in the brain - it receives excellent reviews year after year, it is highly interactive and social, and the setting is remarkable.

New paper alert! 🚨

We found that the brain's compass is remarkably stable at two scales

1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit

This may be key to how the brain aligns its other maps.

There are approximately 1000 research groups on the #NIH campuses, including Steve Rosenberg's research group, which develops groundbreaking T-cell therapies for cancer.

Effectively all of those groups were suddenly prohibited from buying any (!) supplies last year.

That is on the leadership.

We think cortex might function like a JEPA. It looks like prediction errors in layer 2/3 are not computed against input (as is the idea in predictive processing), but against a representation in latent space (i.e. like in a JEPA arxiv.org/abs/2301.08243 or RPL doi.org/10.1101/2025...).

Attention-like regulation of theta sweeps in the brain's spatial navigation circuit Spatial attention supports navigation by prioritizing information from selected locations. A candidate neural mechanism is provided by theta-paced sweeps in grid- and place-cell population activity, which sample nearby space in a left-right-alternating pattern coordinated by parasubicular direction signals. During exploration, this alternation promotes uniform spatial coverage, but whether sweeps can be flexibly tuned to locations of particular interest remains unclear. Using large-scale Neuropixels recordings in freely-behaving rats, we show that sweeps and direction signals are rapidly and dynamically modulated: they track moving targets during pursuit, precede orienting responses during immobility, and reverse during backward locomotion β€” without prior spatial learning. Similar modulation occurs during REM sleep. Canonical head-direction signals remain head-aligned. These findings identify sweeps as a flexible, attention-like mechanism for selectively sampling allocentric cognitive maps. ### Competing Interest Statement The authors have declared no competing interest.

The hippocampal map has its own attentional control signal!
Our new study reveals that theta #sweeps can be instantly biased towards behaviourally relevant locations. See πŸ“Ή in post 4/6 and preprint here πŸ‘‰

The oneirogen hypothesis: modeling the hallucinatory effects of classical psychedelics in terms of replay-dependent plasticity mechanisms

Our paper on the "Oneirogen hypothesis" is now up in its revised form on eLife!

This is the hypothesis that psychedelics induce a dream-like state, which we show via modelling could explain a variety of perceptual and learning effects from such drugs.
