AI-controlled brain implants help improve people’s memory
Machine-learning software is being used to prod an individual’s brain into remembering things.
Backstory: Electrical stimulation to improve brain performance isn’t a new idea—but knowing how to deliver the pulses is tough.
First, learn: Researchers from University of Pennsylvania gathered data from 25 epilepsy patients, each with up to 200 electrodes already implanted in their brains for monitoring purposes, while they performed memory tasks. That formed a training set for AI to learn personalized models about how brain activity relates to remembering something.
Then, do: The same elec
