Happy to say our ultrasound paper is now out in Brain Stimulation
doi.org/10.1016/j.br...

We used cultured neurons to dissect mechanisms of ultrasonic neurostimulation.
Most surprising: even an extremely short (4µs) single low-intensity pulse can generate neuronal activity.

🧠 Postdoc Position !
Join us in Paris to work on brain-machine interfaces (BMI) using functional ultrasound (fUS)! We're seeking a postdoc to further develop and validate fUS-based BMI with Caltech and Iconeus.
