(ETH) – Over the next few weeks, a company called Kernel will begin sending dozens of customers across the U.S. a $50,000 helmet that can, crudely speaking, read their mind.

Weighing a couple of pounds each, the helmets contain nests of sensors and other electronics that measure and analyze a brain’s electrical impulses and blood flow at the speed of thought, providing a window into how the organ responds to the world. The basic technology has been around for years, but it’s usually found in room-size machines that can cost millions of dollars and require patients to sit still in a clinical setting.

The promise of a leagues-more-affordable technology that anyone can wear and walk around with is, well, mind-bending. Excited researchers anticipate using the helmets to gain insight into brain aging, mental disorders, concussions, strokes, and the mechanics behind previously metaphysical experiences such as meditation and psychedelic trips.

“To make progress on all the fronts that we need to as a society, we have to bring the brain online,” says Bryan Johnson, who’s spent more than five years and raised about $110 million—half of it his own money—to develop the helmets. Johnson is the chief executive officer of Kernel, a startup that’s trying to build and sell thousands, or even millions, of lightweight, relatively inexpensive helmets that have the oomph and precision needed for what neuroscientists, computer scientists, and electrical engineers have been trying to do for years: peer through the human skull outside of university or government labs.
