This is one of my favorite optical illusions, because even when you know specifically HOW IT WORKS, it's still hard to make your brain believe it. The image below is real-world video, but you're being tricked into believing it's an elaborate miniature by the DIORAMA EFFECT. Let's talk about it.

Another unknown birthday: Amongst the earliest recorded woman in #mathematics, Hypatia lived during the 3rd century AD in Alexandria, Egypt, which was part of the Roman Empire. 🧪🐡👩🏼‍🔬🧮 🔭 #histsci She was born at some time between about 350 & 370 & died in 415 C.E. She taught philosophy, #astronomy & 🧵
My linocut portrait of Hypatia in purple holding an astrolabe up to her eye with her left arm while her right rests on geometric diagrams on sheets of paper on her table. Astrolabe and table plus diagrams are bronze in colour. I’ve shown her with curly hair piled up on her head, in a loose tunic with sash. Behind her are two Doric columns and arch.

When and why do modular representations emerge in neural networks? @stefanofusi.bsky.social and I posted a preprint answering this question last year, and now it has been extensively revised, refocused, and generalized. Read more here: doi.org/10.1101/2024... (1/7)

🚨 New preprint! Why do some insights from spikes translate to field potentials while others don't? In this paper we compare visual memory representations in spikes and LFPs to propose a general framework that answers this question. www.biorxiv.org/content/10.6... 🧵 (1/10) 🧠🟦 🧠💻

Parietal cortex is causally required for state-dependent decisions

Parietal cortex is causally required for state-dependent decisions
Animals fluctuate between high and low performance states during decision-making. Bandi et al. demonstrate that parietal cortex is causally required for maintaining high-performance states during auditory localization. Parietal cortex population activity distinguishes performance states and exhibits enhanced correlational structure only during the high-performance state, unlike primary auditory cortex.

Great article - I remember reading in Newton's biography that he stuck a blunt-end knitting needle between his eyeball and the bone so he could press the back of his eyeball and see colours. He clearly didn't have any students at that point in his career 🙂

I wrote a post about how cool it is that scientists in the 1800s figured out that our color vision must arise from three types of cells just using clever behavioral experiments (a century before we recorded from the cones in the eye!) adiatelic.substack.com/p/history-of... #neuroskyence #SciComm 🧪

The rod:cone ratio in mice is 33:1, in humans (outside the foveola) is 15:1, but is 1:7 in the 13-lined ground squirrel (13LGS). How is this dramatic shift in the rod:cone ratio achieved?/2

Ooh great paper! Wonder why (rat) mPFC here doesn't contain irrelevant stimulus info ('early selection') but (monkey) PFC in the Mante-Sussillo style task has both ('late selection'). Reminds me of this reply by Flesch et al, discussing differences in irrelevant stimulus info in fMRI vs monkey PFC.

Just finished 'Playing with Reality' by @kellybclancy.bsky.social. Loved it! I picked it up because I thought it was about the history of games, which it is... but it's also so much more than that. Touches upon game theory, minimax, RL, economics, auctions, evolution, Simcity, and more.

It's finally out! Visual experience orthogonalizes visual cortical responses Training in a visual task changes V1 tuning curves in odd ways. This effect is explained by a simple convex transformation. It orthogonalizes the population, making it easier to decode. 10.1016/j.celrep.2025.115235
