In a study, now out in Attention Perception & Psychophysics (by @Psychonomic_Soc), @ananyapassi and I have some cool insights about how parts combine in sound-shape associations (in the famous Bouba-Kiki effect). Read on to find out more! 1/12

Causal reasoning lies at the core of human intelligence but few studies have tested its neural basis. In a new study, we find that despite its importance, causal reasoning is implemented not in a single unified brain system, but rather in separate domain-specific regions.

Amazing
Brilliantly made video explaining the art of chitra-kavya, the art of solving fascinating optimization problems using letters! Super happy to see my open-source TTS, Vāgdhenu (prathosh.in/vagdhenu/), being used in such magnificent ways. Thanks for creating this, @udbhava.

The science is clear! Keep children away from phones. Use a parental control app like google family link and regulate your child's phone time. Be a role model and keep your phone aside at home and spend time with your kids 🙂
New in Science: we randomized phone-free classrooms for 16,000+ students across 10 institutions in Odisha, India. Students deposited phones in a box at the start of each class, for a full semester.

Leading AI models appeared to predict brain activity equally well… …until we asked them to synthesize images that precisely control neural firing, like these 👇 Across 25 neural sites, closed-loop experiments revealed striking hidden differences in model-brain alignment. 🧵

Vision is awesome!
On the left: fixed shadow → it looks like the ball rises On the right: shadow moves with it → it looks like it glides on the floor Your brain uses shadows to judge 3D motion

Chat with AI and have it build your own cognitive task and connect data all for free! What's not to like? Try this out and let us know your feedback!
1/ AI has taken care of most of the coding. It hasn't touched the rest of running a study: hosting, recruitment, paying participants, monitoring, analysis. Still a different platform for each. We built VibeMyExpt to put it in one place vibemyexpt.com

Preprint alert! We've done the first ever wireless brain recordings from the high-level visual & motor regions (IT/PMv/PFC) in monkeys engaged in natural behaviors as well as during controlled screen-based tasks. Read below for a lay summary and the link for details! 1/8

Key events during these interactions elicited distinct and reliable neural signatures that reflected the encoding priorities of each region. Visual and motor regions were clearly dissociated in screen tasks, but were dissociated only at specific events in the natural task. 7/8

Neurons active while seeing food were reactivated during sleep. Taken together, our results reveal that reliable neural signatures in high-level sensory and motor regions form the neural substrates for natural behaviors. 8/8
