Bacteria Found in Fish Brains Challenge Brain Sterility

Scientists just found living bacteria inside fish brains and it completely challenges everything

we thought we knew about the brain. For decades we believed the blood brain barrier kept the

brain totally sterile and protected from any microbes. But here is the wild part.

Your nose sits millimeters from your brain and it is absolutely packed with bacteria. A researcher decided

to study fish brains and discovered actual living bacteria thriving inside. This means the brain

might have its own microbiome just like your gut does. If this holds true in humans it could

revolutionize how we understand neurological diseases and mental health. The brain might

not be the pristine fortress we always imagined.
