💬 "It's really about trying to give individuals agency and the information to make decisions so that they can better care for their brain." If you’ve ever wondered what it’s like to try a Kernel Flow headset, what Kernel’s technology can do for you now, and where the future of brain measurement is headed, @Hilarx takes you along on her visit to Kernel HQ with CEO, @RyanMField. @BusinessInsider article linked below to learn about: - @bryan_johnson's thought process when founding Kernel - The technology behind Kernel Flow - The current participant experience (Brain Age and Cognition Trackers) - Kernel’s hope for the future + real world applications businessinsider.com/bryan-jo…

We agree and have worked with several teams building brain foundation models. They turned to the Kernel Flow device, the only scalable, plug-and-play whole-head TD-fNIRS device on the market, because they hit a ceiling with EEG alone. TD-fNIRS measures a hemodynamic proxy of neural activity, the same signal that is used by functional MRI, and has been shown to relate to complex brain states and mental representations. Every non-invasive modality has its trade-offs. EEG captures sub-millisecond electrical dynamics, while TD-fNIRS provides localized hemodynamic state data. Because they measure distinct physiological processes with largely independent noise profiles, pairing them makes the whole greater than the sum of its parts. Our next system now pairs whole scalp TD-fNIRS with whole scalp, 30-channel EEG. It is the best hardware and platform to build the next generation of brain foundation models and neuro-AI applications. It is a proven platform, with already 40,000 hours of brain data collected across our partners. And while the NVIDIA comparison is a lot to live up to, it may well be on point for what we have built!

This is how AI and brains come together. @KernelCo is showing real-time NeuroAI capabilities powered by @nvidia at @NeurIPSConf. Come check out Kernel Flow to see how NVIDIA Jetson Thor enables image reconstruction, data visualization, and activity classification from streaming Flow data all optimized by NVIDIA Holoscan. Find us at the Foundation Models for the Brain and Body Workshop on Saturday, December 6th (demo session I at 10:15am). Workshop agenda: brainbodyfm-workshop.github.… List of demos: brainbodyfm-workshop.github.… Following the NeurIPS conference, we will be posting example data and reference code on the NVIDIA Holohub repository: github.com/nvidia-holoscan/h… so anyone can quickly get started with new AI applications on top of this combined platform. #NeurIPS2025 #NeurIPSanDiego #NeuroAI

I'm going to have Kernel Flow in tow with me for about a week in San Francisco and I thought it would be fun to do a BrainAge scan pop-up in the area. I'm trying to gauge interest. Fill out this form if you're interested in getting your brain measured and learning more about your brain health! lnkd.in/gunQSEvb @kernelco

Did you know that @bryan_johnson raised over $100M to develop a @neuralink alternative? Ryan Field, CEO of @KernelCo joins today's podcast to discuss Kernel's ground breaking fNIRS technology and the cool applications being built on top of it like measuring BrainAge and predicting which antidepressant you'll best respond to.
