for the first time in history, a brain implant has been approved for commercial sale. you can actually buy one.

it's called neo. costs around $15,000.

the question everyone asks first: does it actually work?

here's what the implant does.

a coin-sized chip gets placed on the surface of the brain, right over the area that controls movement.

when a paralyzed patient imagines moving their hand, the chip reads that signal, sends it to a computer, and the computer drives a mechanical glove that moves for them

picking up objects, gripping utensils, handling daily tasks.

all from thought alone.

the whole surgery takes an hour and 40 minutes.

surgeons thin the skull, open a small window, and place two electrodes directly on the surface of the brain.

then they close it up, patients go home within a week.

32 patients with spinal cord injuries were implanted in a clinical trial led by huashan hospital
