Check out this new work from my hugely talented colleague & friend @taherehtoosi
How does our brain excel at complex object recognition, yet get fooled by simple illusory contours? What unifying principle governs all Gestalt laws of perceptual organization? We may have an answer: integration of learned priors through feedback. New paper with Ken Miller! 🧵

The Dutch newspaper NRC covered our Nobel Laureates paper and made this excellent figure (my translation). It shows the SES rank of each laureate's father. You can clearly see the increase in access to scientific opportunities for lower/middle class families in the modern era.

Mary Brunkow and Fred Ramsdell – who have been awarded the 2025 Nobel Prize in Physiology or Medicine – gained decisive insights into how autoimmune diseases arise. Brunkow and Ramsdell made a key discovery in 2001, when they presented the explanation for why a specific mouse

1/ Excited to share a new preprint! Our latest study uncovers how serotonin precisely controls the “time window” for fear learning, ensuring that our brains link cues (CS) & threats (US) only when it’s adaptive. #Neuroscience #FearLearning

Fear learning is a critical adaptive mechanism that enables the association of an environmental cue (the conditioned stimulus, CS) with a potential threat (the unconditioned stimulus, US), even when...

Stress is complicated, right? @USkupio @ampolter & I had a hard think about the way acute & chronic stress impacts the different neural populations in the VTA & I’m really pleased with what we came up with. Just published in TINS. Check it out! https://t.co/HpJbQzmi8f
