A study published in the journal JAMA Network Open and conducted by included researchers from the University of São Paulo ...

Connecting the olfactory bulb and the nasal cavity is the olfactory nerve. Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain ...

which are connected to each nasal cavity by the olfactory nerve. Olfactory bulbs help detect and process scents and odors, passing information from the nose to the brain. Microplastics have been ...

"So when you breathe through your nose, your olfactory nerve directly samples particles and reacts to the particles that you are inhaling as a direct sensory mechanism," said Dr. Wells Brambl ...

For the first time, scientists have detected microscopic microplastics lodged in the human brain. Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected ...

Nerve ablation: In rare situations, hyperosmia can be such a severe problem that you may need surgery. This will decrease the function of the olfactory nerve so that the odors you smell will not ...

The underlying mechanism of phantosmia is the disruption of the olfactory system. With olfaction, odor molecules are typically absorbed by olfactory receptors in your nostrils which send nerve signals ...
