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 ...

New research from an international team of scientists has demonstrated how odors evoke memories in the brain, in ways stronger than other senses. Using neuroimaging and intracranial electrophysiology, ...

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 ...

Adult neural stem cells/progenitor cells residing in the basal layer of the olfactory epithelium are capable of reconstituting the neuroepithelium even after severe damage. The molecular events ...

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 ...
