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 ...

Olfactory dysfunction is associated with aging and the earliest stages of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s diseases; it is thought to be an early biomarker of cognitive ...

Animals depend on their sense of smell to locate food, identify mates and evade danger. In mammals, olfactory perception typically relies on G protein–coupled receptor (GPCR) pathways. Insects, by ...

Microplastics are tiny pieces of plastic that have been found all over the world and in the human body. Oregon State University via Wikimedia Commons under CC BY-SA 2.0 Microplastics are inescapable.

Olfactory dysfunction serves as a potential early diagnostic biomarker for Parkinson’s disease (PD), providing essential evidence for investigating PD pathogenesis and developing neuroprotective ...

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 ...

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 ...

Sensory pathways in Drosophila to detect and avoid 2MT are shown. Flies escape from 2MT through olfactory, taste, and nociceptive sensory pathways. This study identified that TRPA1 expressed in taste ...

Researchers from the National Institute for Physiological Sciences/the Exploratory Research Center on Life and Living Systems (ExCELLS) in Japan identified a TRPA1 stimulant acts as a novel insect ...
