The same neuron can tell fruit flies to walk toward the smell of rotting fruit and speed up, according to new research from ...

The ultimate goal is to use this mouse-tissue model of olfactory sensory neurons as a pathway to developing a human organoid that can be used to screen drugs to treat people whose sense of smell is ...

Summary: Researchers have identified a new brain pathway in mice that links the smell of food to feelings of fullness, offering insight into how scent influences appetite. When lean mice smelled food, ...

This happens within a few seconds because the nerve cells are directly connected to the olfactory bulb. The nerve cells react to different food smells, but not to other smells.

Your olfactory nerve has a vital role in your nervous system. If that nerve becomes damaged, it creates a lot of consequences for other parts of your head and nose.

The investigators examined olfactory bulb tissues from 15 deceased Sao Paulo, Brazil, residents ranging in age from 33 to 100 years who underwent routine coroner autopsies.

The researchers’ finding suggests the possibility of designing pharmaceutical or genetic therapies to turn on new neuron production in old or injured brains.

Study Overview The study examined the olfactory bulbs of fifteen deceased individuals, aged between 33 and 100, all of whom had resided in São Paulo for over five years.

While more research can help confirm these findings, the results support that the olfactory pathway, which has to do with smell, could be a way for microplastics to enter the brain.
