The team suspects that neurogenesis happens in other parts of the adult brain, too. In mice, new neurons are regularly made ...

A better understanding of human smell is emerging as scientists interrogate its fundamental elements: the odor molecules that ...

Sitting in a parking lot on a Saturday morning, my senses were overwhelmed by scents from several fast food joints. It triggered a memory and took me back.

A paper published Monday in Nature Medicine found that the tiny fragments of plastic are passing the blood-brain barrier and into human brains, and the amount of microplastics in the brain appears ...

The nose, she knows, is loaded with bacteria, and they’re “really, really close” to the brain—mere millimeters from the olfactory bulb, which processes smell.

After years of curiosity, she decided to confront her suspicion in her favorite model organisms: fish. Salinas and her team* started by extracting DNA from the olfactory bulbs of trout and salmon, ...

How Is the Brain Affected? 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.

Eight out of the 15 brains studied had microplastics in their olfactory bulbs. However, these eight samples had only 16 microplastic particles between them, which is perhaps some comfort.

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.

A study published in JAMA Network Open confirmed that microplastics can be present in the olfactory bulbs of the brain in people, based on their analysis of 15 deceased people.

Olfactory bulbs help detect and process scents and odors, passing information from the nose to the brain. Microplastics have been found in human brains, according to recent research that has not ...
