Bryan Johnson describes Kernel's new brain-measurement device that uses lasers and light sensors to detect neural activity safely and cheaply. The technology could make brain scans routine and affordable for billions of people, shifting mental health from neglected to central in how we care for ourselves.
Six years ago, I wondered whether it would be possible to build a brain interface that billions of people could use. Currently, it's pretty easy to measure most things in our body. The one thing we can't routinely measure is our brains. This is a result of a team of scientists and engineers that have built this over the past six years. This is version three. It's a combination of lasers and detectors. So it shines light inside the head. The photons then go in and bounce around. Some come back out and you can then record the activities. It's safe. It's been proven safe for decades. The beauty of this is the mind is forgotten until it's the only thing that matters. And it's very hard currently to get data on our brains. What this does is allows anyone to have their brain scanned in an easy, low cost way and it could make a huge difference in the way we care for our minds.
