Researchers have found evidence of microplastics in the olfactory bulbs of the human brain for the first time, after detecting them in the colon and the bloodstream.

Microplastics can invade the olfactory bulb of the human nose, which transmits smells to the brain, a new study found.

Researchers have identified microplastics in the human olfactory bulb, highlighting a potential pathway for these particles to enter the brain and raise concerns about their long-term neurological effects.

Scientists in Brazil found microplastics in the brain tissue of cadavers, according to a new study published Monday in the journal JAMA Network Open.

Microplastics have been found in brain tissue above the nose, suggesting a likely passageway for microscopic plastic shards and fibers to enter the brain after already being discovered in nearly every organ in the human body, according to a new study published Monday in the journal JAMA Network Open.

The olfactory nerves run from the inside of the nose, through the skull, and then directly into part of the brain called the olfactory bulb. The researchers suggest that microparticles breathed into the nose may somehow get transported along the olfactory nerves and into the brain.

Microplastics continue to be found in some concerning parts of the human body. A new study published Sept. 16 in the JAMA Network Open journal explains how microplastics in the human brain can affect an important part of our daily lives: how we smell.

Microplastics are inescapable. These miniscule plastic particles have been found at ancient archaeological sites, in freshly fallen snow on Antarctica, at the top of Mount Everest and deep in the Mariana Trench.

Since then, more than 7,000 published studies have shown the prevalence of microplastics in the environment, in wildlife and in the human body. So what have we learned? In a paper released today, an international group of experts,

Scientists in Brazil have found more evidence of microplastics infiltrating the human body. While it has been previously reported that microplastics were found in human brain tissue, this recent study discovered these tiny particles in the olfactory bulbs of the brain which are responsible for processing smells.
