The first time I understood the impact of neuromodulation was while witnessing a deep brain stimulation surgery during my first year of medical school. What stuck with me--more than anything else--was the way the patient's face lit up when her symptoms disappeared. Surgical…
Half the world will experience a brain disorder in their lifetime. At @nudge, we're building brain interfaces that are safe, precise, and non-invasive to solve that problem. We've raised a $100M Series A led by @ThriveCapital and Greenoaks to go faster. We're hiring. Join us.
Truly the best

Proud to support the @newlimit team: @byersblake, @brian_armstrong, @jacobkimmel. A great example of a new type of bio company that starts with helping sick people on the way to enhancement for all humans.
We’ve raised a $130 million Series B led by @kleinerperkins alongside new investors @natfriedman/@danielgross , @vkhosla, and @humancapital — joined by existing investors @foundersfund , @_DimensionCap, and @brian_armstrong (yes, the cofounders are doubling down). We also raised…
We've raised a $100M Series A from @ThriveCapital, @greenoaks, and a host of great angels. Everyone’s brain can work better. Engineering that idea into reality is the most impactful advancement we can make to life.

I'd argue there is no job in the world with greater potential for outsized impact. Please share with the most incredible leaders you know.
Big news: we’re kicking off the search for ARIA’s next CEO. This is a once-in-a-lifetime opportunity to lead one of the most ambitious orgs in science and tech. 1/8
This is a digital voice-box for a man with paralysis. It translates his intention to speak into sounds with the timing latencies of able-bodied people. @Maitreyee_W made this incredible work happen and has set a new benchmark for the field.
Our brain-to-voice synthesis brain-computer interface paper was published in @Nature today! This neuroprosthesis synthesized the voice of a man with ALS instantaneously, enabling him to ‘speak’ flexibly and modulate the prosody of his BCI-voice. 1/7 Paper: rdcu.be/eqH3C
How to be more emotionally intelligent (without trying so hard) 🧵 for @threadapalooza
It is hard to convey just how hard Maitreyee has worked leading this project. Fantastic job and results! 👏👏👏

Congrats @ikauvar and team, beautiful work
Congratulations to our Human Neural Circuitry team; bit.ly/4dEyX7Z publishes today in Science! This was the hardest challenge of my career, but one of the most rewarding, after years of rebuilding– & for myself, expanding my inpatient neuropsychiatry work to the service…
Our paper on the “sweetspot” for focused ultrasound in essential tremor was finally published last week in science advances! So happy to finally share this work and so thankful to everyone who helped make this happen. Read it here: science.org/doi/10.1126/sc… @MGBneurosurgery
Such a great event by @ARIA_research in London these past few days. Looking forward seeing what comes next @JacquesCarolan @ilangur


Congrats Susan!
Congrats to @UCSFHospitals neuro-oncologist Susan Chang, MD, for receiving the Lisa DeAngelis Award for Excellence in Neuro-Oncology Education from @NeuroOnc in recognition of her dedication to advancing the field through new teaching & mentoring initiatives! 🎉@UCSFCancer
More great work from @YuhaoHuangMD and co at Stanford. Great to see more progress quantifying pain states in real time. Big implications for next generation of therapeutics for pain
Our paper was just published in Nature Communications. Acute pain leaves reliable neural and facial signatures that can be tracked in natural contexts, thus promising objective, real-time pain monitoring. With @StanfordNsurg @DrCoreyKeller, @VivekBuchMD @josef_parvizi…

Congrats Eddie, so well deserved
Big News: We are proud to announce that @UCSF's Chair of Neurosurgery, Edward Chang, MD, has been elected to @theNASciences — one of the highest honors given to American scientists! 🎉
