It was a fun few hours hosted by the inimitable Paul
I'm not sure what a representation is anymore... or maybe I never knew. These fine folks have some thoughts...
"Moderate-high intensity aerobic or low-intensity flexibility exercise for 12 months in participants with aMCI may provide protection against decline relative to usual care" alz-journals.onlinelibrary.wiley.com/doi/10.1002/al…
In the cerebellum, neurons are placed in competition with one another, nulling the downstream effects of each other's spikes, in a well-organized subtractive process that produces a fast changing, precise output from a collection of slow, noisy neurons.
Some of my thoughts on OpenAI's o3 and the ARC-AGI benchmark: ⬇️
Fireside chat with Karl Friston @PhysicsNews @KarlFristonNews
Very concerning
The internet has been progressively diluted with AI-generated slop. Are medical records headed for the same fate? 🧵 I just published a perspective in @NEJM with @AdamRodmanMD and Arjun Manrai on why rushing AI into medical documentation could be a mistake.
Very useful indeed
So many people confuse LLMs (or genAI, in general) for models of human cognition, language, learning, etc., so I thought it may be useful to share once more my brief comment, titled "Psychological models and their distractors". (open access link: rdcu.be/cGQpY) 🧵
Excited to be part of this
“The knowledge from this project could lead to new treatment approaches down the road for improving stroke recovery.” Neuroscience research led by @UNC_SOM faculty @AdamHantman and @ShihYYI, along with @blamlab John W. Krakauer at @HopkinsMedicine, has the potential to improve…

A recent study examining the kinematics of 3D arm movements in individuals in the sub-acute phase after #stroke found that both weakness and synergy intrusion contribute to motor deficits during the sub-acute period. journals.sagepub.com/doi/full/10.11… #neurotwitter #neurorehabilitation
We just released @fchollet keynote talk from #AGI24. He challenges LLM hype, discusses ARC-AGI benchmark, and proposes merging deep learning with program synthesis for true AGI progress.

Was fun to provide a commentary on @ProfLaurenRoss and @DaniSBassett piece on mechanism.
Lauren Ross @ProfLaurenRoss and @DaniSBassett outline the different ways neuroscientists use the term mechanism, and they gather insight from nine scientists on how this variety makes it difficult to clarify standards in the field. thetransmitter.org/the-big-pictur…
Do bumblebees prefer continuous over interrupted strings to get to an artificial flower with nectar? Yes ... but does this mean that they understand the physics of a continuous string...? Find out in our latest paper in eLife: elifesciences.org/articles/97018
Fascinating - yet again pointing towards the separation between language and thought with the latter in the driving seat.
Curious about the origins of structured thought? In the latest @CurrentBiology I share some thoughts on @ljuba_pi @JR_Hochmann & colleagues' new study showing that infants grasp complex social relations, w/ implications for language & thought. Take a look! authors.elsevier.com/a/1jpcG3QW8S6F…
The CoT hype balloon just exploded. (And kudos to @rao2z’s group for all their outstanding work on LLMs.)
