Scientists have grown tiny human brains and inserted them into robots

Yes, you read everything correctly. Scientists have really grown small brains, which are cellular structures that emit brain waves. To catch neural activity, they were placed in a spider-like robot which was sent into space. These small brains are tiny cellular structures that perform specialized functions. They are called organoids. Organoids include ribosomes, chromosomes, mitochondria, and other components of cells. In the laboratory of the University of California, scientists turned human skin cells into stem cells, and then ensured that the organelles developed like brain cells in embryos. Has the future really come?

Scientists have created tiny brains and inserted into robots. Yes, the future has come!

Why grow organoids?

It all started six years ago. It was then that scientists first created the brain organoid from human skin cells. Today they are grown in laboratories around the world. This gives scientists the opportunity to take a fresh look at the earliest stages of the development of the human brain.

The organoids that are now in spaceafter all the manipulations carried out, they turned into balls the size of a pinhead, each of which contains hundreds of thousands of cells of different types. Each of which, in turn, produces the same chemical and electrical signals as the cells in our brain.

Did you know about the existence of a robot that penetrates directly into the human brain?

NASA sent organoids straight aboardInternational Space Station to see how they will develop in zero gravity. They were put in a metal box along with bags of nutritious broth. Experts believe that at this stage, organoids reproduce incredibly fast.

But the most interesting thing is that scientistsmanaged to record simple brain waves emanating from organoids. Brain waves are complex patterns of nervous activity. They are created in the brain of an adult by synchronous networks of neurons. Specific brain patterns appear when we dream or indulge in memories.

Scientists recorded the brain waves of these tinycerebral organoids and also found that as they mature, wave changes resemble changes in the developing brain of premature babies. Does this raise a number of complex ethical questions for researchers, do you think? Let's discuss this in our Telegram chat.

Lead author of the study Dr. PriscillaMuotri and her colleagues are testing different ways to stimulate organoids so that they can develop more complex neural networks. In one experiment, they placed the organelles in a small spider-shaped robot. The computer translated the electrical activity of the organoid into instructions, upon receipt of which, a small arachnid robot began to move its feet.

work in the laboratory of the University of California, which communicated with the organoid through a computer.

To understand that he was approaching the wall during movement, the robot used sensors that determine its location. The computer transmitted these signals to the organoid in the form of electrical pulses.

To date, scientists can not yet say whether these experiments will affect the further development of organoids. Read even more dizzying stories on our channel in Yandex.Zen.

Secrets of the human brain

As you know, the brain is the most complex organ inhuman body. Scientists are still wondering about many aspects of his work. And that is why organoids are so attractive - these relatively simple neural balls mimic some characteristics of a full-fledged brain. However, a new study published Thursday in Cell magazine suggests organoids may have a more complex structure than previously thought.

The data obtained may be a sign thatscientists are approaching the ability to generate at least partially conscious life in the laboratory. If so, neuroscientists will have to face a serious ethical dilemma - continued experimentation may mean the creation and destruction of a self-conscious, human-like life.

Many scholars relate to such assumptions.skeptically, however, the author of the study encourages his colleagues to think carefully about what they can create, albeit inadvertently. Do you think organoids have consciousness?
