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

New research reveals that microplastics can penetrate the brain through the nasal passages, prompting urgent questions about their impact on human health and the environment. Study: Microplastics ...

The threads and microplastic pieces were discovered in the olfactory bulb, the part of the nose responsible for detecting odors that sits at the base of the brain. “Once present in this ...

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 ...

Phantosmia, also known as an olfactory hallucination or "phantom smells," occurs when you smell odors that are not there. The perceived odors may be constant or come and go. The most common include ...

However, they do not exhibit the structural abnormalities that are most indicative of an early gestational disturbance (ie, reduced nasal cavity volume and shallow olfactory sulcus). Although data ...

Odorants binding to olfactory receptor neurons (ORNs) trigger bursts of action potentials, providing the brain with its only experience of the olfactory environment. Our recordings made in vivo from ...

Natural environments feature mixtures of odorants of diverse quantities, qualities and complexities. Olfactory receptor neurons (ORNs) are the first layer in the sensory pathway and transmit the ...
