Job alert! We are seeking a rodent in vivo electrophysiologist to work on coordination between anterior thalamus and hippocampus in rats using Neuropixels. Beautiful Scotland, leading university (Glasgow) and vibrant intellectual setting. Post is 23 months but hopefully extensible. Details here ๐Ÿ‘‡

Such a beautiful study: Cognitive ethology of nest building in a shell-dwelling cichlid: Current Biology www.cell.com/current-biol...

They even 3D printed "sinistral shells" and showed that the fish can adapt to the altered geometry.

Amazing. What I find most impressive is how he goes around the rock to approach from another angle. Cool spatial awareness.

Rapid concerted switching of the neural code in the inferotemporal cortex - Nature Face cells in the macaque inferotemporal cortex are initially able to detect faces and then rapidly switch to a face-specific neural code to discriminate between different face identities.

This looks like a significant discovery from Doris Tao's lab:

A photograph of the anglerfish species Bufoceratias wedli from the Field Museum of Natural History imaged in vivid green and red. It looks upsettingly like a warped human head with thick red lips and small red teeth and a large chin. Its tiny tail sticks out of the back like a ponytail. CREDIT: Matthew Davis

A digital drawing of a vivid green and red merperson with a large head inspired by the photograph of the anglerfish. The pectoral fin of the anglerfish has become an ear; the tail of the anglerfish has become a ponytail. There are small red ear and nose piercings. The merperson appears happy, and sits in a tucked position reminiscent of a little old grandmother. The drawing is signed by the artist, Danna Staaf.

Got sent a press release for this awesome paper doi.org/10.1643/i202... by @anoplogaster.bsky.social and became instantly obsessed with the much-too-human face of the attached anglerfish photo (credit: Matthew Davis), so I had to give it a body

New paper (with lots of cute animal videos!)

Ever watch your dog "run" while asleep and wonder whatโ€™s going on in their brain? In Current Bio we suggest that those twitches aren't just leaky dreamsโ€”theyโ€™re a vital maintenance system for the most precise movements

You underestimate the colossal pain of academic silence. They say trauma is when you go through tragedy without even compassionate observers.
Dehumanization happens when thereโ€™s silence, no expression of collective pain.
Are we not seen as humans? Colleagues?
Would you all be so silent about MIT?

Emotion Concepts and their Function in a Large Language Model

transformer-circuits.pub/2026/emotion...
This got press hate because of the word "emotions" but it is cool work. "Internal motivational states" serve as a form of working memory that helps animals organize their behavior, so why not ask if similar computational primitives help LLMs to do the same?

Love this. I like to think about those forrest birds thinking about their "shrill and high-strung" city cousins and talking to their kids like: Ah those stressed souls, don't move to the city, kid!

Tried openalex.org as replacement. It's comparable, though has its flaws too (I don't think it's superior).
