You don't have to talk, you can communicate with your brain.
I still remember the once-popular Indian drama "P. K"?
In this Chinese-language comedy movie called "My God," P. from an alien planet. K made a lot of jokes because he knew nothing about the earth. One of the interesting plots is that in P. K's hometown, people use the brain to communicate, as long as they hold the other's hand, you don't have to talk, you can know what the other person is thinking, so in their world everything is clear and direct, no deception, no concealment .
Of course, this is just a beautiful idea put forward by the film. The normal communication in real life is still inseparable from our hands and mouth. But according to a new study from Stanford University, in the future, people may also be able to communicate through the brain.
The new study is to establish a connection between the human brain and the computer, and then use the human brain to control the computer.
Researchers implant a tiny electrode implant in the human brain, roughly the same size as an infant with aspirin. After implanting in the human brain, when people begin to imagine hand movements in their minds, There is a cursor movement on the computer screen connected to the brain.
The emergence of this system is a major milestone, indicating that the way people communicate with people with severe physical weakness or paralysis (such as ALS and spinal cord injury) may change significantly in the future. In this new study, there are three Participants were tested, two of whom had amyotrophic lateral sclerosis (ALS or Lugley's disease) and one had spinal cord injury.
The researchers placed one or two electrode arrays in their brains that recorded signals from the motor cortex, which normally controlled muscle movement.
