Our brain contains live bacteria!



The bacteria that live within the human intestine are responsible for many things, which affect our health, our genes, and even our emotions.

Scientists are constantly studying the effect of bacteria on humans, but the most striking recent evidence is the presence of "microbial brain brains" in the head.

Initial results were presented at the 2018 annual Neuroscience, held in San Diego by researchers at the University of Alabama at Birmingham.

The important reason is that so far we still learn how intestinal bacteria affect brain function and behavior, and new suggestions show that the human brain has a population of bacteria, and this could be an important discovery if it can be confirmed in the future.

In the study, the team led by neurologist Rosalinda Roberts tested brain samples from 34 people who died, about half of them schizophrenia, and the rest of the group were healthy before they died.

"We conducted brain surgeries in a sequential manner, all of which contained bacteria in different amounts," the authors conclude. The bacteria density varied according to where they were located in the brain area, and it was a capsule and a nucleus and ribosomes and a bladder. Its presence is in large quantities in the black matter, the hippocampus and the prefrontal cortex.

They also found astrocytes whose function was how neurons connected to each other was discovered.

As to how the bacteria reach the brain, researchers still do not know, but reports believe it can be transmitted by blood vessels.

While the team recognizes that microbes have been transferred to the brain tissue by surgical infection in post-mortem operations, the way it has spread along the tissues does not indicate this.

The group's next experiments found that this bacterial phenomenon was not confined to the human brain, but some studies on mice showed evidence of brain bacteria in healthy mice.
