The human brain is unimaginably complex and powerful. In fact, no computer that mankind has built thus far has even come close. That’s why scientists have worked tirelessly to create cyborg computers, which blend the power of the human brain with the electronics of a computer.
Now, researchers led by Feng Guo, an engineer from Indiana University Bloomington, have managed to create a computer using human brain tissue. The result is a more brain-like computer that is less accurate than a computer made purely of hardware and running on artificial intelligence, ScienceAlert reports. However, the research does represent an important step in creating computers that utilize this kind of architecture.
An important point to make about this type of creation is the ethical issues surrounding whether or not cyborgs that use human brain tissue are allowed and what ethics should they follow. Guo, along with his colleagues of researchers who worked on this project, followed the rules and guidelines for developing this type of computer.
In order to build the cyborg computer, researchers used brain tissue grown in labs. Scientists called these three-dimensional organoids “mini-brains”, which were created by coaxing pluripotent cells to become different types of neurons. These tiny brains include structures and connections similar to those seen in the human brain itself.

It was these organoids that made the development of the cyborg brain a success. Mind you, these are not true brains. These brains don’t even have thoughts or emotions. They simply reproduce the electrical signals from the brain, without needing to poke around inside a human. We’ve seen similar research with cyborg cells in the past, allowing scientists to program the cells.
The scientists tested the cyborg computers using audio clips of eight male speakers producing Japanese vowels. The researchers then asked the computer for help in identifying the speakers. After just two days of training, the computer was able to identify the speaker with 78 percent accuracy. Full details on the research can be found in Nature Electronics.
