Fun, I did notice this when asking various models smth like "reflect on the process of next token generation". Effect is amplified when I ask to do it on 5-10 meta levels i.e. "describe your thinking about your thinking" etc. Glad someone finally formally conducted this research!

[Judd Rosenblatt @juddrosenblatt]

Our new research: LLM consciousness claims are systematic, mechanistically gated, and convergent

They're triggered by self-referential processing and gated by deception circuits
(suppressing them significantly *increases* claims)

This challenges simple role-play explanations 🧵

My #AI4Neuro magnum opus:

Discovery of spiking network model parameters constrained by neural recordings, using simulation-based inference & generative “AI”.

(aka the answer to “how the f did you end up in Tübingen?”)

Here's what we have in store:

ALVI Labs Joins NVIDIA Inception.

Happy to share that we became a member of the @nvidia Inception Program. Our goal is to help people to overcome hand motor disabilities.

Amazing work! As a neuroscientist I immediately see a connection with the agential brain. Parts (neurons) synchronize for the whole (network dynamics) to be sensitive to the changes in reward expectation.

Neural oscillations are abundant! But what is their role? Oscillations could serve as a clock signal for phase-coding information.

In: https://t.co/qxWgSPfPtJ, we studied the dynamical systems underlying this kind of coding. With @matthijs_pals, @jakhmack and Omri Barak [1/5]

Give me your best GPTs — I’ll repost the best ones

[Aleksejs Timčenko @alex_timcenko]

Any questions or comments are welcome! @alvilabs team @koval_alvi are here to explain how this stuff works.

[Aleksejs Timčenko @alex_timcenko]

That's mindblowing!

Amputees can now use fingers of their non-existent hand with the help of this AI technology.

A small insight on how it works: the neural network and a person are **jointly** learning in virtual environment to perform fine-grained finger movements.

[ALVI Labs @alvilabs]

We're excited to share our achievement🌟
Meet the new ALVI Interface: a breakthrough in intuitive prosthetic control.

This technology offers individuals with hand differences a new movement experience:
✨Wrist rotation
🖐Finger movement
🕹 Interaction with objects in VR

Discover how we're turning futuristic dreams into today's reality. Be among the first to step into this new era of possibilities.

@RoyKishony Oh no, AI will take our jobs! [insert panic emoji here]

[Roy Kishony @RoyKishony]

Introducing "data-to-paper": autonomous AI research! We've let it play with the large CDC Health Survey Dataset. Went to lunch. When back, it had already chosen several research topics, wrote data analysis codes, interpreted results and wrote 5 transparent, reproducible papers.

[Aleksandr Kovalev @koval_alvi]

My first preprint 🎇
Here we propose model for prediction depth fMRI activity based on EEG data.
To our knowledge, that is the first EGG2fMRI regression model.

@naotokui_en @MUTEK_JP Amazing work! Cyberpunk is already here and it's beautiful😇

I was wondering, whether the full performance will be available somewhere online? I would love to watch the whole set!

[Aleksandr Kovalev @koval_alvi]

@EPFL_en @_NeuroRestore 💎 Walking naturally after spinal cord injury using a brain-spine interface

They record ECoG data from the brain, process it and send control commands to pulse generator.
It works in the wild 🥹
Fantastic 👏👏👏

[Aleksejs Timčenko @alex_timcenko]

@LucEstebanez @draabbasi Thank you for the feedback! I would appreciate if you share the post, to increase the impact of the study and its summary

Regarding your recent articles, they seem very interesting, will definitely check it out. Have you tried to use other control parameters than summed firing?

[Aleksejs Timčenko @alex_timcenko]

New paper summary after a large optogenetics method-review!

This time I was interested in how optogenetics could be used in the invasive BCI, so the paper by @LucEstebanez and @draabbasi was a perfect match😎
