Howard Hughes Medical Institute researchers have discovered that pheromones essential for mating behavior in mice are recognized by the nose and not by the vomeronasal system, as researchers had long ...

Animal reproduction is supported by the integration of various external and internal processes. These processes include a combination of perceived sensory cues, behaviors and hormone secretion. 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 ...

Taiwanese scientists have linked abnormalities in the olfactory region of mouse brains with behaviors connected to autism spectrum disorder, using a novel artificial intelligence (AI)-based brain ...

By targeting an often-overlooked sense, you could sharpen your mind – and help protect your brain from cognitive decline ...

Olfactory dysfunction is a prevalent non-motor symptom of Parkinson’s disease (PD). This dysfunction is a result of neurodegeneration within the olfactory bulb (OB), the first processing area of the ...
