Being inside an MRI machine is not a pleasant experience. You’re in a tiny claustrophobic tube surrounded by a giant magnet, and instructed to lie extremely still.
To Dr. Mary Lou Jepsen, CEO and founder of Openwater, the solution is simple in concept: shrink the machine down to the size of a ski hat, a bra, or a bandage, and manufacture the gadget at the cost of a smartphone. The trick, she explains, is to move away from magnets and instead turn to light. The human body is translucent to red and near-infrared light, allowing our tissues—including both skull and brain—to be illuminated.
Dr. Eric Leuthardt, a neurosurgeon at Washington University in St. Louis [is] experimenting with ways to capture the brain’s movement instructions using wearables.
Leuthardt found that using a cap embedded with electrodes, he could reliably pick up the low-frequency signals generated by the premotor cortex. These “planning” signals are then sent to a machine learning algorithm to parse out the intended movement. Finally, the results of the computation are used to control a prosthetic to carry out the movement.
…[This could democratize] the technologies, allowing more people to manipulate their brain activity without first going under the knife.
