Olfactory function is preserved in about a quarter of patients with Parkinson’s disease (PD), and may be predictive of disease course, say researchers. Olfactory testing has been used as a screening ...

Olfactory sensory neurons are nasal neurons that make use of hundreds of different types of odorant receptors to analyze odorous chemicals in our external world and send that information to our brain.

The nearly 2,000 glomeruli that cover the surface of the olfactory bulb are so distinctive that they were noted specifically in the earliest of Cajal's catalogues. They have variously been considered ...

Patients with chronic rhinosinusitis (CRS) with nasal polyps exhibited significant improvement in olfactory function when treated with a combination of oral and nasal steroids vs nasal steroids alone.

Bill-wiping, or the scraping by a bird of its bill along a substrate, has been observed in social contexts and cited as an irrelevant displacement activity. However, several behaviors once categorized ...

Exposure to ultrafine particles from traffic alters the expression of many genes in human olfactory mucosa cells, a new study shows. The study is the first to combine an analysis of emissions from ...

Searching for new ways to help my senior patients improve and maintain cognitive functions, I came across an interesting research study from the University of California Irvine (Woo, C. et al. 2023) ...
