"Scientists use ultrasonic mind control on monkeys" as Elon Musk Says His Neuralink Will Do Human Brain Implant in “Less Than a Year”

Scientists have for the first time directed the decision making of monkeys using remote, ultrasonic brain stimulation.

For the study, published Wednesday in the journal Science Advances, researchers had a pair of macaque monkeys participate in a visual test designed to investigate basic decision making. 

The monkeys were made to look at a target at the center of a screen before being presented with a second and third target to the left and right sides of the screen, one following the other.

Typically, macaques and other monkeys glance at the target that appears first, but researchers were able to alter the tendency by directing low-intensity ultrasound waves at the frontal eye fields of the two monkeys, the brain region that controls eye movement....

Elon Musk: Neuralink Will Do Human Brain Implant in “Less Than a Year”
"We are already a cyborg to some degree."

For the second time in two years, entrepreneur and billionaire Elon Musk sat down with podcaster Joe Rogan to chat about the future of AI and its role in the symbiosis of man and machine.

In their conversation, Musk revealed that the secretive brain stimulation link startup Neuralink, which he co-founded, is close to starting testing in actual humans.

“We’re not testing people yet, but I think it won’t be too long,” Musk told Rogan. “We may be able to implant a neural link in less than a year in a person I think.”

The news comes after Musk teased in February that the brain-computer interface startup was working on an “awesome” new version.

Back in July 2019, the company showed off plans to shoot holes in subjects’ skulls with lasers and feed flexible threads of electrodes into their brains.

In his most recent chat with Rogan, Musk revealed that the company’s implant is about one inch in diameter and has to be implanted by removing a small section of the skull.....

The monkey stuff seems a bit more 'elegant' as mathematicians are wont to say.
