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 ...

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 ...

The representation of stimulus identity and experience is transformed from primary olfactory cortex to memory-related multisensory areas in the hippocampus.

Can a simple scent released while you sleep improve your sense of smell, your memory or even the quality of your sleep? New ...

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 ...
