Neural waves of three distinct registers combine to give the brain a picture of what's being smelled, according to a Northwestern Medicine study published in PLOS Biology. This is a full ...

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 ...

For decades, neuroscientists assumed the inside of a mammal’s nose was essentially a jumble: more than a thousand types of ...

Scents are not only processed by the olfactory center, but also by the brain’s reward and aversion systems, explaining how scents can take on meaning. “We already knew that there is a connection ...

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

Alzheimer’s disease is often linked with memory loss, but the earliest signs can be much more subtle. One of the first ...

In people with epilepsy undergoing a pre-surgical monitoring technique called stereo-electroencephalography, electrical leads from a type of depth electrode are implanted throughout the brain. Kehl ...

The odor receptors in the nose are not distributed at random but organized in a precise spatial pattern, two new studies ...

Most of us take our senses for granted, at least until one of them stops working. But despite the usefulness of smell, sight, touch and the other senses, they took millions of years to work themselves ...

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 ...

Once a scent is detected, different areas of the brain are activated. A team has recently discovered that structures of the olfactory sense work closely together with the brain's reward and aversion ...
