New paper in @elife.bsky.social led by Tianhe! Motor errors shape everyday actions—from spilling milk to missing a hold while climbing. Why are some errors systematic? We show motor biases arise from misalignment between visual and proprioceptive reference frames. tinyurl.com/t7h786m5

If you can substitute "hungry ghost trapped in a jar" for "AI" in a sentence it's probably a valid use case for LLMs. Take "I have a bunch of hungry ghosts in jars, they mainly write SQL queries for me". Sure. Reasonable use case. "My girlfriend is a hungry ghost I trapped in a jar"? No. Deranged.

New preprint! tinyurl.com/y6z57dsm How do people discover an effective strategy when the environment shifts—say, when adapting to an unfamiliar trackpad? Our take: strategic motor adaptation isn’t a smooth process of error reduction but rather a process of hypothesis testing. 🧵

This commentary will always remain one of my favourite. Well written and rings true to this day. "You can't play 20 questions with nature and win" by Allen Newell, 1973 www.coli.uni-saarland.de/~crocker/doc...

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp.... genzplyr is dplyr, but bussin fr fr no cap.

"In a landmark study, OpenAI researchers reveal that large language models will always produce plausible but false outputs, even with perfect data, due to fundamental statistical and computational limits." www.computerworld.com/article/4059...

I'm officially recruiting grad students in FIU's Cognitive Neuroscience PhD program! 🧠✨ The @bottenlab.bsky.social uses precision and population approaches to study neurodevelopmental variability. Reach out if interested! (contact info on bottenlab.github.io) Apps due 12/1! cn.fiu.edu (pls share)

An M.I.T. study found that 95% of companies that had invested in A.I. tools were seeing zero return. It jibes with the emerging idea that generative A.I., “in its current incarnation, simply isn’t all it’s been cracked up to be,” johncassidysays.bsky.social writes.

Ever stared at a table of regression coefficients & wondered what you're doing with your life?

Come to talk to me about parity, AD, and anything else at #AAIC25 today!!

Today at 3:30 my top PhD student @clara-gallay.bsky.social will present my poster at the amazing Guided Electronic Poster Tour about Sex and Gender in AD. Don’t miss it! @barcelonabeta.bsky.social #AAIC25

I have deleted the data that were in the database and which you were probably saving for production Forgive me I was panicked So artificial And so intelligent

📊 Silent changes, serious risks: US gov datasets quietly altered A new study found nearly half of 232 US health datasets were changed, mostly replacing 'gender' with 'sex', without logging or explanation. 🔗 www.thelancet.com/journals/lan... #SciComm #Data 🧪

Happy 18th birthday ggplot2! #rstats

Thank you again @ibroorg.bsky.social for giving me the opportunity to go to the 2025 Biomarkers Course at UCL. This was hands down the best course I've ever attended! Massive thanks to Dr. Aitana Sorgov-Esteve, Dr. Ross Paterson and Dr. Michael Schöll.

Thanks for an amazing #ParentalBrain2025 meeting @susanacarmona.bsky.social and Prof. Oscar Vilarroya! It felt uplifting to have so many people from around the globe come together. One of the best conferences I've been to in a while 🧠✨

Yesterday we had the pleasure to have at @barcelonabeta.bsky.social two amazing reserchers @magdamartinezga.bsky.social and @grotzinger.bsky.social , from @emilyjacobs.bsky.social lab, talking about “Advancing the Neuroscience of Human Pregnancy”

Excited to be heading to Barcelona next week for the Parental Brain Conference! I’ll be speaking on “Promoting Big Datasets & Collaboration in Human Maternal Brain Research through @bowers-wbhi.bsky.social ” on Friday, May 9. Can’t wait to connect with this amazing community! #PB2025

I'm super happy to have received funding from @ibroorg.bsky.social to attend the 2025 Biomarkers for Neurodegeneration workshop, taking place at @ucl.ac.uk this year! Looking forward to it 🧠🧪

A phenomenal opportunity in Switzerland 🇨🇭 for students interested in a PhD in vision neuroscience! Dr. Teichmann is an outstanding scientist and mentor.

A study in Nature Aging finds that structural economic inequality is linked to reduced brain volume and connectivity in middle-aged and older adults across the Americas, more so in Alzheimer’s disease than in frontotemporal dementia. https://go.nature.com/4fRE2t6 🔒

Some years ago I wrote a simple R app to explore colors in HCL space. While it's clunky, it still is my preferred way of selecting colors, because it offers features other color selectors don't normally have. Today, thanks to shinylive, the app is available standalone. 🧵
