The tiny scraps of plastic were found in the olfactory bulb, the part of the brain responsible for processing smell.

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.

Neurons in the olfactory epithelium also offer an easy way for viruses to bypass traditional central nervous system barriers by providing a direct a pathway to the brain.

Microglia in the olfactory bulb have a nose for protecting the brain from infection Nervous system cells act as middlemen to stimulate immune system response Peer-Reviewed Publication NIH/National ...

The olfactory bulbs, located at the bottom of the brain with one in each nasal cavity, contain different kinds of nerve cells that are responsible for helping us smell.

The olfactory bulb is one of the most ancient parts of the brain in evolutionary terms, Landrigan noted. "In the human skull, it sits forward of the rest of the brain.

Researchers at the University of New Mexico have identified the presence of bacteria in the healthy brains of fish.

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 ...

A new study identified the tiny pollutants in the olfactory bulbs of eight cadavers, suggesting microplastics can travel through the nose to the brain ...

The olfactory bulbs, located at the bottom of the brain with one in each nasal cavity, contain different kinds of nerve cells that are responsible for helping us smell.

The study published on Monday in the journal JAMA Network Open revealed that eight out of 15 autopsied adults in Germany and Brazil had microplastic inside the brain’s olfactory bulb.

Bottomline The discovery of microplastics in the olfactory bulbs of the human brain marks a significant milestone in understanding the potential health risks associated with plastic pollution.
