A living computer has been created from the human brain.

Swedish scientists have created the world’s first living computer made from human brain tissue. The “living computer,” which exchanges information like a normal computer chip, is predicted to be capable of solving global energy crises.

Swedish Scientists Create the World’s First Living Computer from Human Brain Tissue

The cells, grown in a lab and consisting of clusters of 16 brain cells, communicate information among themselves.

The new computer works very similarly to a traditional computer chip, acting like circuits that send and receive signals through neurons.

What makes this new technology special is its lower energy consumption, as living neurons use millions of times less energy compared to current digital processors.

Scientists have discovered that tasks requiring our brains to use 10 to 20 watts of energy require 21 megawatts of energy in today’s computers. This shows that current computers use a thousand times more energy than the human brain.


The mini brains, about 0.5 mm in diameter and consisting of 10,000 living neurons, are trained with doses of dopamine. When they perform tasks correctly, they receive a flow of chemicals as a reward.

Scientists stimulate specific areas by exposing them to light to mimic dopamine release. The organoids are surrounded by eight electrodes and can measure activity.


This breakthrough blurs the lines between biology and technology, opening up new possibilities in computing and neuroscience.

While there are many ethical considerations, the living computer represents a significant milestone in the field of technology.

This technology challenges our perceptions of what is possible and raises profound questions about the future of artificial intelligence and humanity’s relationship with technology.
