New brain-computer interface preprint led by PhD student Tyler Singer-Clark! This video of a man with paralysis accurately controlling a cursor looks like something you've seen since ~2017. BUT! This is driven by multielectrode arrays in ventral (speech) motor cortex‼️ 1/

These is the same @BrainGateTeam participant ('T15') and arrays reported in our recent high performance speech neuroprosthesis paper. Except now Tyler added a 2D plus click velocity decoder that enables the participant to use a mouse by attempting hand movements. 2/

Using a rapid online calibration protocol (like what @DrDavidBrandman demonstrated in his 2018 JNE paper), we found that the participant could achieve accurate cursor control in about a minute (training from scratch). 3/

To our surprise, after some hyperparameter optimization, cursor control from the "wrong part of the brain" [is this becoming my catch-phrase🤔?] was the second-best in the published literature (importantly this does not include the recent @neuralink bps records). 4/

We think this is important because it means that with an implant optimized for speech neuroprosthesis performance, good cursor control comes "for free". Now our participant has full keyboard AND mouse control of his personal computer. 🧠➡️⌨️🖱️ Preprint:

Fantastic work, as always. The flexibility in BCI that this could afford folks with ALS is a potential game changer.

Neuralink's motor cortex explained. It works with threads. Electrical activity in the motor cortex becomes digital output on a screen. Cursor from thought. Add threads in language regions. Decode internal speech before it’s spoken. No keyboard. No mic. Brain-to-text interface. Source: Noland Arbaugh Neuralink

A paper in Nature Medicine presents an intracortical brain–computer interface (BCI) that enables long-term, independent speech-based communication and computer use in an individual with severe paralysis.

We’ve been cooking at Prophetic. An ultrasonic brain computer interface that can precisely modulate the clusters of neurons in the prefrontal cortex. This will unlock is a new human capacity to experience dreams.

NEW: This beanie lets you type with just your thoughts. Sabi just emerged from stealth with a brain-computer interface you wear like a beanie that turns internal speech into text on a screen. • Noninvasive interface worn as a cap or beanie • 70,000–100,000 sensors for high-density brain signal capture • Trained on 100,000+ hours of neural data • ~30 words per minute at launch, improves with use • Backed by Khosla, Accel, Initialized, and Kevin Weil Sabi feels like the first real attempt at a consumer BCI.

i've been wanting to try out this idea of controlling a remote computer from your phone with a touchpad-style interface... i kinda like it! not sure what it's useful for but it seems reasonably usable

Creating computer animation by hand in the 1990s was incredibly demanding—this is what a true pioneer looks like.

New preprint from our group, led by Lissa Ventura Antunes, explores structural changes in arterioles with cerebral amyloid angiopathy. Lissa is a master of quantitative 3D microscopy. In this clip, healthy tissue is first, then two cases with CAA. @VUMCneurology Vanderbilt University Medical Center

THIS GUY JUST FULLY VIBECODED A 3D GAME THAT'S BETTER THAN MOST STEAM GAMES?? this is genuinely one of the craziest vibecoding projects ive seen in awhile, if you showed this to anyone even the AI hate group they would think this was built by a human with care, possibly in years but it was fully vibecoded with cursor, by just doing lots of planning in cursor apparently I wonder how video games will be made in a year...

This looks like CGI, but it's actually 100% real water. 🤝 Back in 2017, Gatorade brought ‘Water Man’ to with 2,048 water jets and strobe lights to build a moving 3D human frame by frame.
