Machine learning algorithms used to decode and enhance human memory
When it comes to brain measurements, the best recordings come from inside the cranium. But people—and institutional review boards—aren’t usually amenable to cracking open skulls in the name of science. So Kahana and his colleagues collaborated with 25 epilepsy patients, each of whom had between 100 and 200 electrodes implanted in their brain (to monitor seizure-related electrical activity).
Kahana and his team piggybacked on those implants, using the electrodes to record high-resolution brain activity during memory tasks.
