Brain implants that last for years without replacement are becoming more realistic — so far in monkeys.
According to a CorTec press release, the data, published in the proceedings of the 10th Graz Brain-Computer Interface Conference, come from two rhesus macaques with µECoG surface electrodes implanted at Weill Cornell Medicine. In the animal that remains in the study, one of 64 contacts failed after about 14 months, and the other 63 are still recording more than four years after implantation; in the first animal, with a smaller 8-contact array, all contacts worked until the planned end of the study. The same electrode platform underlies the Brain Interchange system, which is in clinical evaluation at the University of Washington. The data are preclinical and provided by the manufacturer itself.
