A group of scientists from the US taught the birds to reproduce sounds they did not know before.

While the developers of one of the many Ilon Mask Neuralink companies are working on a device that can be implanted into the brain of a paralyzed person to control gadgets, neuroscientists in the United States have already learned how to manage the brain neurons of animals and implant false memories with them.

Optogenetics is one of the methods of neuroscience that allows you to influence the nerves in the brain by light rays. In this way, scientists activated certain circuits of neurons and literally made animals remember new sounds.
