In 1951, Adelbert Ames created the mind-boggling ‘Ames Window’. It’s so effective that even when you know how it works you can’t break the illusion. https://t.co/GSTRlRD9DG

🔥 Technical blog post (with maths and code) on how to render 4D objects, by @adonisHigh 🔥
Ever wondered how a 4D Shepard-Metzler shape is made and how perspective projection lets us see it? Ep. 02 of Spaceland is out! Give it a look: https://t.co/sYn84Zysx7

We need to support Zohran Mamdani. If Mamdani loses, Zionism will win. If all New Yorkers want to fight against Zionism and avoid losing their city to Israel, they should vote for Mamdani.

Prediction is vital for the brain, but not everything. When observations are noisy, estimation improves by looking back. We argue that even single neurons can be retrospective—like LGN lagged cells and olfactory bulb mitral cells:

It's fascinating to me how the visual system of the brain can perceive this animation as a single, shapeshifting, 3D object even though it's composed of many, quasi-independent, small parts moving in different directions. This is not unlike observing the murmuration of a flock of

After a long journey, I’m thrilled to share that this work is now published.
A novel model inspired by the cerebellum—a part of the brain that plays an important role in controlling movement—helps explain how organisms adapt to changing environments. @TianHWang @BerkeleyPsych

Artificial neural networks were invented as models of the brain and and now rapidly approach human-level cognition. Does this mean that the mystery of human intelligence has been solved? I grapple with this question here. https://t.co/dfm8cupLpN

How does our brain excel at complex object recognition, yet get fooled by simple illusory contours? What unifying principle governs all Gestalt laws of perceptual organization? We may have an answer: integration of learned priors through feedback. New paper with Ken Miller! 🧵
