Think your brain is on the fritz? Just grow a new one.

According to new research, scientists have developed a miniature brain capable of giving off its own brain waves (“Brain waves detected”, 2019).

These “cerebral organoids” are created from human stem cells and grown in an environment that simulates the same setting the actual human brain grows in (“Brain waves detected”, 2019).

“‘You can use brain organoids for several things, [to] understand normal human neurodevelopment, disease modeling, brain evolutions, drug screening, and even to inform artificial intelligence,’” stated Alysson Muotri, a biologist at the University of California, San Diego (“Brain waves detected”, 2019).

The researchers developed more refined ways to grow the organoids to test their neural activity over a span of months, and just recently did they notice these brains had the same frequency as growing, infant brains.

Overtime, they began to develop even more consistent brain waves due to developing connects between neurons (“Brain waves detected”, 2019).

To confirm if the organoid brains were on a similar growth path as actual infant brains, the researchers compared the brainwaves from the organoids to ones given from a machine algorithm that mimics the brain waves of premature babies (“Brain waves detected”, 2019).

Sure enough, their growth was comparable.

“‘It might be in that in the future, we get something that is really close to the signals in the human brains that control behaviors, thoughts, or memory…’” stated Muotri (“Brain waves detected”, 2019).
