In a new paper led by @matthewshinkle.bsky.social, we use a pre-trained deep neural network (DNN) to model brain activity and to make detailed visualizations of feature selectivity across many brain areas. In plain English: we make pretty pictures of what different parts of the brain like to see.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

About 18 years ago, my Postdoc advisor dropped an undergraduate student in lab and asked me to teach her. I asked her career plans. She said she was going to be an astronaut. I glibly replied “ok well let’s work on your plan B”. She’s about to blast off into space in an hour.

📣 CALL TO ACTION -

Yesterday, the House Appropriations Subcommittee that determines the funding for NSF proposed a 23% cut to NSF’s 2026 budget.

If one of these members listed is your representative, use our link to easily call your rep & demand NO CUTS to NSF➡️ actionnetwork.org/call_campaig...
Red banner at top reads “CALL NOW! Demand NO CUTS to NSF Funding in the FY 2026 Budget!” Below are three sections: “What’s Happening” explains the House CJS Subcommittee marked up the NSF budget; “Why It Matters” warns of a 23% funding cut; “What You’ll Do” urges people to call if their rep is on the list. Statue of Liberty background and “next page” arrow at bottom. Graphic with a red banner reading “CALL NOW! Demand NO CUTS to NSF Funding in the FY 2026 Budget!” Below is a list of 12 members of Congress (Republicans and Democrats) with their states and districts. “Stand Up for Science” logo at bottom.

🧪 BREAKING (good news): Senate subcommittee says NO! to Trump's proposed slashes to NASA & NSF funding.

Today, the subcommittee said to keep NASA + NSF funding at $33.9 billion, the same as in FY24.

See 7:15 below. Full Senate appropriations committee meets tomorrow about it.

Out now in TiCS, something i've been thinking about a lot:

"Physics vs. graphics as an organizing dichotomy in cognition"

(by Balaban & me)

relevant for many people, related to imagination, intuitive physics, mental simulation, aphantasia, and more

Hey, if you need a breather from the news, we have pretty brain pics to distract you! We made an interactive viewer showing images optimized to elicit responses from different places in the brain. Link to viewer in 🧵

Why should you care? We think this viewer provides a powerful tool for exploratory neuroscience, particularly for hypothesis generation, and that this type of visualization provides a raw, direct way to show what elements of natural images are important for particular parts of the brain.

Finally, we didn’t stop at pretty pictures - we generated images to elicit strong responses from specific regions in the brain (FFA, EBA, RSC) and showed them to people while we scanned their brains with fMRI. This worked; by and large, images elicited high responses where they were intended to.
