A better understanding of human smell is emerging as scientists interrogate its fundamental elements: the odor molecules that ...

For example, the olfactory nerve is essential for detecting smells. The functions of the cranial nerves are sensory, motor, or both. Sensory cranial nerves help a person see, smell, and hear.

Our results illustrate the spatial distribution of 2-3 top genes from clusters 0 to 3 in the olfactory nerve layer (Figure 7; corresponding tSNE plots are in Suppl. Figure 2 for comparison). In ...

The olfactory bulbs are a critical component of people’s ability to smell. Researchers of this study note that the olfactory pathway from the neurons in the nose to the brain could allow certain ...

Many might remember last year’s research from URI showing that microplastics breached the blood barrier to the brain of lab mice after they ingested liquid with polystyrene. By Cheryl Auger The ...

Campen said it’s more likely that nanoplastics enter the brain through the bloodstream, which picks up plastic bits from the lungs or digestive tract, rather than the olfactory bulb.

Objective: The aim of this study was to compare the olfactory function between hairdressers exposed to formaldehyde and unexposed controls, as exposure to toxic agents is a potential cause of ...

From the olfactory bulb, nerves pass into your olfactory tract, which is located below the frontal lobe of your brain. Nerve signals are then sent to areas of your brain concerned with memory and ...
