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 in ...

Microplastics were found in the olfactory bulbs of eight of 15 human brains at autopsy. A total of 16 different synthetic polymer particles and fibers were identified in olfactory bulbs. The olfactory ...

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 ...

Viruses can inflame and disrupt connections between the olfactory system, which governs the sense of smell, and the part of the brain associated with memory and learning, possibly accelerating the ...

In a recent article published in Scientific Reports, researchers investigated the changes in olfactory bulb volume and structural connectivity of the brain in patients with olfactory dysfunction (OD) ...

Two articles in Nature and Science that address fine points of signal transduction in olfactory neurons--the cellular pathways that get turned on in response to an odor--have far-reaching implications ...

A novel bilateral compensatory mechanism important for the activity of olfactory glomeruli in Xenopus tropicalis tadpoles was uncovered.
