Scientists have developed a brain-computer interface that uses electrodes implanted into the brains of the animals to mimic the brain waves of other animals and the human body.
The results are the latest advances in brain-imaging technology that could lead to more advanced prosthetic devices and artificial intelligence.
They could pave the way for future prosthetic technology that would work better with the human brain, rather than the animal brain.
The technology uses electrodes placed on the foreheads of the brain and spinal cord of a labrador retriever and a poodle.
The electrodes transmit signals to a computer that converts them into electrical impulses that can be used to control a robotic arm.
The labrador retrievers brainwaves are modulated with electrical stimulation to mimic human brainwaves.
They also use artificial intelligence to create a “digital interface” with their computer.
Researchers say the technology can be more accurate than previous methods and would be more suitable for use in hospitals.
Dr Tomi Roeder, a professor of neurobiology at the University of Wisconsin, said the researchers were hoping that the new technology could lead the way to developing more advanced devices.
“It’s the next step, the next evolutionary step, to allow people to have a better understanding of the human condition and the environment,” she said.
“We need to start with an understanding of what makes us tick and then hopefully build on that knowledge to make us better.”‘
It’s a new way to control’The researchers believe that the electrodes on the brain can be connected to a prosthetic arm.
They say the prosthetic could then communicate with the labrador to help it make decisions that would be difficult for an animal to make.
“The way the brain works is that it’s a big loop, and it’s really a loop of feedback loops,” Dr Roeder said.
“We want to understand how the brain processes these information.”
The scientists say that the system can detect how well a user is doing on the computerized task and then adjust the system accordingly.
“You can imagine it as an animal’s digital assistant,” Dr Tomi said.
“So you would go through these loops, and they might give you the correct answer, and then you would ask them, ‘So, what’s the correct response?’
And then you could ask them again, and this time you could get the correct reply.”
The technology could also be used in the rehabilitation of people who are severely handicapped.
Dr Roeder says the project could be extended to other animals to see how they respond to the new prosthetic.
“If they can understand what’s going on in the brain, we could maybe work with other animals that are similarly impaired, so that we can use this kind of system to help people with some of their disabilities,” she explained.
The study was funded by the National Institutes of Health and was published in the journal Science Advances.
