Researchers and scientists have always wanted to know how a human brain cell works to increase intelligence? To find the answer to that question, some researchers injected human brain cells into the brains of mice to see how it would affect the mice. Interestingly, researchers found that the mice got smarter and human brain cells implanted in mice boosted their learning ability.
Some researchers at the University of Rochester Medical Center discovered new properties of human brain cells called astrocytes. They believed that astrocytes might have the ability to boost learning ability in animal, specially in mice, if implanted in their body. So, they injected some of the human brain cells into the brains of a group of mice and started to observe the animals.
Around six months later researchers found that mice having some portion of human brain cells in them became smarter than normal (non-implanted) mice. Those mice injected with human cells were able to learn their way around a maze significantly faster, and were also able to quickly associate a distinctive sound with an electric shock.
Co-senior author Steven Goldman said in a statement, “We believe that this is the first demonstration that human glia (precursors to astrocytes) have unique functional advantages. This finding also provides us with a fundamentally new model to investigate a range of diseases in which these cells may play a role.”
Researchers have published their study in the journal Cell Stem Cell. The study has the potential to change the scientific consensus on astrocytes.
