A computer implant inside her skull reduces a young woman’s 400-a-day seizures in her brain to a controlled average of two a month. Science fiction? Nope. Neurotechnology has arrived. All we humans need to do is periodically change the batteries. Before the implant, the now almost normal 27-year-old young worman could not drive a car, attend classes or be left alone for more than half an hour. Electrodes in her implant “listen” for irregular neural activity and calm it with a series of electrical pulses. Every two days, the young lady transmits data from her implant to a laptop and then on to Neuropace, the Mountain View, Calif., company behind the “responsive neurostimulation system,” or RNS, in her head. Her doctor reviews the data and assesses and adjusts her treatment. Cognitive enhancement is here, both for afflicted humans and healthy ones, made possible in large part by Darpa, the U.S. military’s research arm. Darpa’s deep pockets has created a “direct cortical interface,” a breakthough brain-computer connection. Now, resulting neural implants can stimulate and record from just a handful of neurons. In the near future, Darpa hopes to create a neural interface that can connect to as many as one million neurons. Such a brain-computer interface could turn a person into a programmable, debuggable machine and put us in a position to someday refine and evolve our brains. It’s not science fiction any more.
