There's a reason why some people have a natural aversion to fragrance—and it's about more than personal preference. Here, ...

Unlike most of our sensory systems that detect only one type of stimuli, our sense of smell works double duty, detecting both chemical and mechanical stimuli to improve how we smell, according to ...

Olfactory ensheathing cells (OECs), as the name suggests, ensheath and protect the nerve fibres in the olfactory nerve, which transmit olfactory (smell) information to the brain from receptor ...

These changes in both the olfactory nerves as well as in the parts of the brain responsible for perceiving smells may be long term and even permanent, ...

If a person has lost 30% of their olfactory nerve cells, they won't be able to detect enough odour molecules to activate the threshold level for smelling when they breathe normally.

The olfactory nerve connects sense cells in our nose to the olfactory bulb inside our skull. This neural bulb is a massive relay point containing a nest of synapses.

Researchers have only recently discovered an olfactory nerve that they believe is the route through which pheromones are processed. Nerve “O,” as it is called, slipped under the radar for many ...

Rather than focusing on nerve cells, the authors obtained support cells called olfactory ensheathing cells, which normally cover and nurture the axons of nerve cells.

Naegleria fowleri, the brain-eating amoeba, poses a rare but deadly threat in warm, untreated freshwater during summer.

Some data suggested that the virus can infect the nerves that carry smell signals to the brain—olfactory neurons. Thus, the lost senses could be caused by direct infections.

Some 86% of people with mild cases of Covid-19 lose their sense of smell and taste but recover it within six months, according to a new study of over 2,500 patients from 18 European hospitals.
