At just 6, this child with #SpasticDiplegia had selective dorsal rhizotomy surgery at UCSFChildrensOakland and worked hard in rehab. Now look at them at 16! This is proof of perseverance and expert care. ucsfbenioffchildrens.org/clinics/cerebr… #SDRsurgery UCSF Neurosurgery

can there be an option to make a “temporary chat” permanent Sam Altman … half the time I start a temp chat, then I’m like this is actually important 🙏🏼

The History and Future of Brain Implants - Full Episode This is our deep dive with Sumner L Norman into the world of brain computer interfaces. We trace the centuries of work that led to the rise of companies like Neuralink and Forest Neurotech and where this is technology is

Can AI help understand how the brain learns to see the world? Our latest study, led by Joséphine Raugel from FAIR at AI at Meta and École normale supérieure | PSL, is now out! 📄 arxiv.org/pdf/2508.18226 🧵 A thread:

We’ve been busy, that’s 3 surgeries in the past 3.5 weeks. Lots of exciting updates coming soon.

I like the analogy of the "bicycle for the mind", because riding a bike requires effort from you, and the bike multiplies the effect of that effort. I don't think the end goal of technology should be to let you sit around and twiddle your thumbs.

congrats Paul! 🇬🇧

To really understand a concept, you have to "invent" it yourself in some capacity. Understanding doesn't come from passive content consumption. It is always self-built. It is an active, high-agency, self-directed process of creating and debugging your own mental models.

I used the Neuralink to write code for an Arduino to allow me to control an RC airplane with a quad stick. The possibilities are truly endless. Thank you Elon and the entire team at Neuralink. I am honored to be part of such a great program. Neuralink

LLM-like models become exocortex of humans (BCI but noninvasive) they observe our life but from our perspective with our emotions and goals developing for us with us we, robots, organizations, industry become neurons of world brain mostly imperceptibble for us - thankfuly world

We are looking for a condensed matter theorist to join our team at Periodic Labs. Consider applying if you are an expert on applying formal condensed matter theory to real quantum materials.

if you’re looking for a more science based HN; hopefully this can evolve / supplant what old science Twitter was

the point about scalability is kind of true (if we take “invasive” == surgeries) ; non-invasive BCIs scale to billions, invasive ones don’t. The “more neuronal signals” framing isn’t technically right until we have some breakthrough.

update: I'm building a new sEMG interface with some friends from Imperial Neurotech to see how far we can push wrist-based neural interfaces. The current generation of wearables is clunky, uncomfortable, and doesn’t feel like the interface layer for what’s coming next: AI companions,

Happy weekend to those who celebrate

this idea could also be extended to personal BCIs. once BCIs are ubiquitous and effectively constructing / representing a mirror image of how we think about / process information, they can be used to broadcast that “image” and aid the process of matching the right person to the
