Visual homogeneity computations in the brain enable solving property-based visual tasks
Seemingly disparate property-based tasks (oddball search, same-different and symmetry) are solved by computing a novel image property, visual homogeneity, which is localized to the object selective co...

In a study now out in @eLife, @GeorginJacob @PramodRT9 and I have some exciting results: a novel computation that helps the brain solve disparate visual tasks, a novel brain region that performs this computation....what's not to like?! Read on.... 1/n

So reindeer (Rangifer tarandus) can't fly, but they are VERY MAGICAL.
For example, their EYES CHANGE COLOR during the year & they're one of the few large mammals that can see UV. Golden brown in summer, deep blue in winter.
Let's talk about the unique visual adaptations of Rudolph and company.

Nature Sci Rep publishes incoherent AI slop. eLife publishes a paper which the reviewers didn't agree with, making all the comments and responses public with thoughtful commentary. One of these journals got delisted by Web of Science for quality concerns from not doing peer review. Guess which one?

Its the AI version of Moravec's paradox:
What we find hard (literature, art, math), AI will find easy
What we find easy (seeing, hearing, moving, laundry), AI will find hard.

This is such a bizarre illusion - the helmet leads to an expectation of a face inside and all I saw was a blurred out face until I realized what's really happening...
It took me a good 30 seconds of staring at this photo to realise that I wasn't absolutely hammered and/or hallucinating. #theashes

Want to know how does the brain encode mass of objects while looking at them? I bring insights to this question from my NHP recordings in my upcoming talk at SfN San Diego, 15-Nov 1.30 PM (abstract 9562 / NANO004.03). Looking forward to all the exciting engagements! #SfN25

I promised to write about my thoughts on the status of the field of neuroAI, some of the big challenges we are facing, and the approaches we are taking to address them. This is super selective on the topic of finding a good model but in my view it affects the field as a whole. Here we go. 🧵

A really cool and clever "second-order" method to gauge how we perceive the occluded parts of objects!
In a new study, out now in Attention Perception & Psychophysics, Thomas Cherian (@thomascherian.bsky.social) and I have some fascinating insights into what we see behind an occluder. Like all good things, the origin of this study was simple curiosity. Consider the picture below:
