🚨New preprint!

Using spinal cord stimulation, we demonstrate that non-monosynaptic corticospinal tract (CST) projections can be leveraged to enable dexterous recovery post-stroke, regardless of MEP status (a traditional measure of CST integrity).

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" https://t.co/oOiRMrDG1h

@behrenstimb @eLife Congrats Tim - not remotely surprised

[Reza Shadmehr @reziliusReza]

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.

Very concerning

[Liam McCoy, MD MSc @LiamGMcCoy]

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.

[John W. Krakauer @blamlab]

Very useful indeed

[Iris van Rooij 💭 @IrisVanRooij]

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: https://t.co/U2T6Vsgl8H) 🧵

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 outcomes for people with brain damage thanks to a $1.3 million grant from the W. M. Keck Foundation: https://t.co/JM0ulQxECn

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. https://t.co/UWVfaSi4aQ

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.
