To enjoy the scent of morning coffee and freshly baked cookies or to perceive the warning smell of something burning, the brain needs two types of cells, neurons and astrocytes, to work closely with ...

The human olfactory system discriminates between thousands of odours by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different ...

Researchers have uncovered novel aspects of astrocyte function in olfactory, or smell, perception revealing changes in their gene expression patterns that turn these brain cells into a hub of ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 118, No. 42 (October 19, 2021), pp. 1-12 (12 pages) Determining the valence of an odor to guide rapid ...

(from left) Prof. Florian Mormann and Marcel Kehl are on the trail of the neuronal mechanisms of human odor perception. We often only realize how important our sense of smell is when it is no longer ...

We often only realize how important our sense of smell is when it is no longer there: food hardly tastes good, or we no longer react to dangers such as the smell of smoke. Researchers at the ...

The sprawling network of the visual cortex reigned supreme in the field of sensory processing, contributing significantly to our understanding of sensory perception. In contrast, the study of ...

A new Northwestern Medicine study has demonstrated how differences in neural activity within the brain's olfactory and orbital cortices cause people to perceive the same odors differently, according ...

In a recent study published in the journal Diagnostics, researchers investigate the relationship between olfactory dysfunction associated with the coronavirus disease 2019 (COVID-19) and subsequent ...
