Olfactory dysfunction links to 139 conditions, with inflammation playing a key role in memory decline and cognitive issues.

Alzheimer's disease is the most common form of dementia and it affects around 944,000 people in the UK. A study has found a ...

"This degeneration leads to a decreased number of olfactory sensory nerves and causes the olfactory bulb to atrophy." And with fewer nerves in this nasal area, "we don't perceive smell as well or as ...

Smell training can improve memory and may stimulate areas in the brain linked to cognition. Your sense of smell is closely ...

They also note the possibility of confounding because the biological matrix of olfactory bulb tissues is similar to a few polymeric materials. For some subjects, researchers could not use one ...

This important study partially fills the gap in the knowledge of olfaction at the level of the Anterior Olfactory Nucleus (AON) and Piriform Cortex with functional magnetic resonance imaging, ...

"Our original hypothesis was that we may find some bacteria in the part of the brain called the olfactory bulb, which is the one part of the brain connected to the nose," Salinas said. "However ...

The odor molecules are thought to activate sensory neurons in the nose, which then send signals to the olfactory bulb. The signals are thought to travel from here to regions of the brain such as ...

The prevailing hypothesis is that it results from damage to nerve fibres that carry signals from receptors in the nose to terminals (known as glomeruli) of the olfactory bulb in the brain.

There is a direct connection between the olfactory bulb (sense of smell), to the limbic system (emotional and memory part) of ...

Research suggests smell training may help improve both cognitive and neuronal functions. Olfactory training could be an ...

Microplastics continue to be found in some concerning parts of the human body. A new study published Sept. 16 in the JAMA ...
