Do we have microbes in our brains? A theory that divides scientists
Briefly

Irene Salinas's recent research suggests the presence of a brain microbiome in fish, challenging the long-held belief that brain sterility is an absolute. This study raises the possibility of microbial involvement in neurological health and disease, stirring debate among scientists. Salinas's findings echo previous research that detected bacterial genetic material in human brains, hinting at a complex relationship between brain health and microbial life, with potential implications for studying conditions like Alzheimer's. As the microbiome's role in human health gains recognition, understanding the brain's microbial landscape could be pivotal.
The study provides compelling evidence for a brain microbiome in fish, suggesting that microbes may play a role in brain health, paralleling discussions in human neurology.
Salinas's finding, while controversial, could illuminate new pathways for understanding neurodegenerative diseases like Alzheimer's, as the interaction between bacteria and neurobiology is explored further.
