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.

New eLife paper is out! We explore the link btw 2-phase perception/generation learning methods like wake-sleep, and what may happen in the brain under on psychedelics. Turns out hallucinations are consistent with hijacking phasic learning, essentially running both wake and sleep phases at once.
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.

Why do we find some scenes more aesthetic than others?
For my first in @sciencenews.bsky.social, I wrote about a new study that suggests that our aesthetic preferences could have evolved as cognitive shortcuts. 🧠🧪

Easy on the eyes is also easy on the brain
A new study finds that the brain spends less energy processing scenes that people find aesthetically pleasing.

Lossy WavPack compression (up to 7× reduction) has minimal impact on sorting accuracy. This offers major storage savings without sacrificing quality.
