Our results thus support the hypothesis that relational coding plays an important functional role in perception and our shared visual world.

Nachum's new book Natural Neuroscience is out! A fresh take on how brains work in the real world—well worth a read.

Are high-order visual cortex representations organized according to purely visual, or also linguistic, principles? Check out the new preprint from our great collaboration with @yovelgalit @ShohamAdva - always a pleasure working with you!

Is the visual cortex aligned with language models as it is with visual models? Only when the text describes the images.

As can be seen, the receptive field structure of entorhinal neurons resembles the basis functions of JPEG, suggesting a form of lossy representation of space in the entorhinal cortex. (4/4)

[Rafael Malach Lab @MalachLab]

Artificial systems are so different from the brain — can they be informative about brain function?
In our perspective with @SimonyErez and @ShanyGrossman, now in PNAS (https://t.co/jLoX34L8rT), we borrow the concept of convergent evolution and argue that, paradoxically, (1/4)

[Rafael Malach Lab @MalachLab]

We illustrate this point, among other examples, by noting a surprising similarity between entorhinal grid cells and the widely used information compression algorithm JPEG (Figure 3, see next). (3/4)

Our results show that what remains invariant across brains is not the activation patterns (population vectors), commonly considered the “work horse” of visual representations, but rather the similarity structure (relational coding) which emerges between these patterns (see fig)

[Rafael Malach Lab @MalachLab]

These results help explain the substantial similarity in perceptual judgments that are observed across individuals. They further point to relational coding as a fundamental representational principle in high order human visual areas.

[Rafael Malach Lab @MalachLab]

Together with the superb Reichman University group: Ofer Lipman, @Doronfried1779 and Yacov Hel-Or and our group’s brilliant alumni @ShanyGrossman, we explored this question by studying intracranial recordings from the visual cortex of patients undergoing clinical diagnosis.

[Rafael Malach Lab @MalachLab]

Why do we all perceive the world in a (largely) similar manner?
This question is not only interesting from a social-neuroscience point of view, but addresses the fundamental issue of neuronal representations of perceptual content in the human brain.
