I like that their implant is simply laid on top of the brain, instead of driving electrodes into brain tissue like Neuralink. I'd like to keep my brain unscarred.
In April, a neurosurgery team from the Mount Sinai Health System placed one of Precision's devices containing four electrode-containing films—totaling 4,096 electrodes—onto the brain of a patient who was having surgery to remove a benign brain tumor. While the patient was asleep with their skull opened, Precision researchers used their four electrode arrays to successfully record detailed neuronal activity from an area of approximately 8 square centimeters of the brain.
This is really cool. Competition in this space should keep things interesting. Where Neuralink shines compared to Precision is that while the Precision solution has more electrodes on a 2D film, Neuralink’s electrodes are on a type of cylinder or similar where the electrodes go deeper inside the brain instead of sitting on top.
