ALGORITHM VALIDATION. “By using this algorithm, the researchers should be able to stimulate the CA1 cells with a pattern that mimics an appropriate CA3 signal even if a person’s CA3 cells are damaged, Berger says. In previous studies on monkeys trained to do the picture-recall task, receiving a juice reward when correct, his group has shown that stimulating CA1 with an appropriate pattern significantly improved the animals’ performance.”
