Our olfactory system, which originated millions of years ago, evolved to detect small changes in the chemical composition of ...

The way that the sense of smell works is that olfactory sensory neurons (OSNs) are wired up to olfactory receptors (ORs) in ...

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 ...

Using computational and theoretical models shows how adult-neurogenesis and spike-timing-dependent plasticity balance the flexibility and stability of odor representations.

A research team has, for the first time, identified at the cellular level why the olfactory system is the first to be damaged in the early stages of Alzheimer's disease (dementia). The paper is ...

Would you give up your sense of smell to keep your hair? What about your phone? A 2022 US study compared smell to other senses (sight and hearing) and personally prized commodities (including money, a ...

Many people think memory loss is the first sign of Alzheimer’s disease, but scientists have known for some time that this is not always true. One of the earliest changes can actually be a loss of ...

The olfactory system is essential for most animals: it supports postnatal survival, detects environmental hazards and mediates emotional, social and nutritional behaviors.

A pioneering study investigating the brain activity of dogs during scent detection has unveiled crucial insights into their remarkable olfactory capabilities. Researchers at Bar-Ilan University have ...
