Human fMRI at 11.7T: Assessing Feasibility, Stability, and Reliability on the Iseult Scanner
Abstract. Ultra-high-field MRI promises major gains in BOLD sensitivity but introduces severe challenges such as RF field inhomogeneity, B0 field inhomogeneity, motion and vibration-induced field vari...

Excited to share our new paper in PLOS Biology! We asked a simple question: when we perceive an odor as weak or strong, does oscillations in the human olfactory system represent the physical concentration of the odor, or our subjective perception of its intensity? 🧵👇

Where, exactly, does learning happen in the brain? Out today in @nature.com, we identify a synaptic locus of birdsong learning and show that the circuit can be tuned to make birds learn faster - but at a cost. Read on👇 #neuroskyence 🧪 #prattle 💬 #bioacoustics Shareable link: rdcu.be/fiyrS

OK, I'm obsessed with this study in @science.org It took Reddit "Am I The Asshole" posts & asked LLMs if the poster was the asshole. Aaand (surprise) AI was more likely to tell people they were NOT the asshole ... even when humans said yeah YTA 🧪 www.science.org/doi/10.1126/...

Sycophantic AI decreases prosocial intentions and promotes dependence
Despite rising concerns about sycophancy—excessive agreement or flattery from artificial intelligence (AI) systems—little is known about its prevalence or consequences. We show that sycophancy is wide...

What makes humans similar or different to AI? In a paper out in @natmachintell.nature.com led by @florianmahner.bsky.social & @lukasmut.bsky.social, w/ Umut Güclü, we took a deep look at the factors underlying their representational alignment, with surprising results. www.nature.com/articles/s42...
