General Application in San Francisco, California at Convergent Research

Arbor is a nonprofit research organization working on one of the hardest open problems in clinical neuroscience: how to change brain circuits by design.

Millions of people with depression, chronic pain, and other brain disorders have no treatment that works. Modulating activity in the brain circuits underlying their symptoms – with electrical stimulation, focused ultrasound, or magnetic stimulation – can work spectacularly well. But it doesn't work reliably, and we can't predict who it will help.

That's what Arbor aims to fix. The starting point is a new class of experiment: intervene, measure how the circuit responds, track the symptom, and repeat in the same individual over months. We’re building the necessary experimental platform. It currently includes the Forest 1 ultrasound system, which works like a wearable functional MRI, but with higher resolution. The system images activity across large brain volumes, including deep brain structures, and will soon stimulate as well. We are also adding electrode-based interfaces in animal studies. From these data, we'll build models to make neuromodulation predictable.

Arbor is a Focused Research Organization within the Convergent Research family, and the new name for Forest Neurotech. We're a mission-focused nonprofit, doing multidisciplinary translational work that doesn't fit in a lab or on a company roadmap. We have the funding to run the first phase, and we're a small team – the people we hire now will shape what Arbor becomes.
