Chinese researchers create ‘human-on-chip’ system using brain matter to create ‘organoid’ robot
Researchers at Tianjin University and the Southern University of Science and Technology in China have created a human-on-chip system that combines human brain matter with a neural interface chip and have used the technology to create a hybrid organoid robot.
The technology is reported to be an emerging branch of brain-computer interfaces, which aims to combine the brain’s electrical signals with external computing power. The idea behind the technology is to develop brain-like computing.
According to the Global Times, the system uses an artificial brain cultivated in vitro – such as a brain-like organ, which can interact with external information through encoding, decoding and stimulus feedback when coupled with electrode chips. In vitro, in this case, means that they’re growing the brain-like organ in a controlled laboratory environment using stem cell technology.
The brain-like organ-growing process allows researchers to create simplified versions of brain tissue that mimic certain aspects of human brain development and function.
So far, the Chinese brain-on-chip interface systems can instruct a robot to avoid obstacles, track and grasp through what is being described as mind control. And to demonstrate the technology, they’ve put the brain-on-chip interface into a humanoid robot.
In an interview, Li Xiaohong, a professor at Tianjin University, reportedly told Science and Technology Daily that brain organoids were regarded as the most promising model of basic intelligence. However, the process has challenges, such as the technology having bottlenecks such as a low developmental maturity and insufficient nutrient supply.
The disturbing aspects of the technology aside – comparisons to Frankenstein’s monster aside – the technology, even with the demonstrative robots, isn’t entirely as creepy as it seems.
While the technology can be used to create thinking robots, it could also lead to new treatments to treat neurodevelopmental disorders and repair brain damage. Brain organoid transplants are considered a promising strategy for restoring brain function by replacing lost neurons and reconstructing neural circuits, the researchers wrote in a paper.
