A Bright Approach to Brain Implants
The Wall Street Journal

The brain was once considered a “black box,” a device so mysterious that you could only guess what it was doing by observing human behavior. You might log its output and glitches, but you’d never parse its code. Scientists are now much closer to engaging the brain in electrochemical conversation—and that could lead to a new generation of high-tech treatments for ailments like stroke, blindness and diseases of aging.

This conversation with the brain has two sides. Neuroscientists call the first “writing in” (sending information to the brain) and the second “reading out” (understanding instructions coming from the brain.) Our senses normally write in—they collect information from the world and convey it to the brain, which interprets it.
