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 ...

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 ...

Scientists in Brazil found microplastics in the brain tissue of cadavers, according to a new study published Monday in the journal JAMA Network Open. Mounting research over the last few years has ...

A new study has presented more evidence backing up a hypothesis suggesting viral infections in the olfactory system can accelerate the progression of Alzheimer's disease (AD). Instead of focusing on ...

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) ...

Researchers found that a Transient Receptor Potential (TRP) A1 stimulant, 2-methylthiazoline (2MT), act as a potent insect repellent in Drosophila. 2MT induces aversive behaviors via olfactory, ...
