Aversion to an offending smell can be an indicator of the organism's capacity to protect itself from harmful substances and live longer. This at least is what happens in the case of nematodes of the ...

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 ...

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

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 ...

Once a scent is detected, different areas of the brain are activated. A team has recently discovered that structures of the olfactory sense work closely together with the brain's reward and aversion ...

Our senses stimulate various parts of the brain. New research in mice shows how smells activate different areas, especially parts of the brain responsible for emotion and memory. The researchers hope ...
