Can functional ultrasound decode what someone is about to do, and what would a wearable version mean for privacy? · Grey Matter

In monkeys recorded through an opening in the skull over the posterior parietal cortex, functional ultrasound predicted from single trials the direction and the effector (eye or hand) of a movement the animal was planning, at about 100 µm resolution.

Can functional ultrasound decode what someone is about to do, and what would a wearable version mean for privacy?

In monkeys recorded through an opening in the skull over the posterior parietal cortex, functional ultrasound predicted from single trials the direction and the effector (eye or hand) of a movement the animal was planning, at about 100 µm resolution. In people it has so far worked only where bone was removed or replaced, as through a transparent skull implant after an injury. A version that worked through intact bone would read intentions in depth without surgery, which is why it is watched as a likely future case for mental privacy rules written for neural data.
