The olfactory system is the sensory system that is responsible for the sense of smell (olfaction). It receives, processes and interprets odour information. Reverse chemical ecology: specific ...

This valuable study shows that an odorant that is typically thought of as a repellant actually activates both attractant and repellant olfactory neurons in C. elegans. Solid evidence is provided that ...

Despite this, how the olfactory system contributes to the cognitive decline observed in PD has remained largely unexplored. Recently, the researchers identified two distinct subpopulations of ...

Their findings point to never-before-seen fast-updating signals in a feedback loop between the brain's olfactory cortex and olfactory bulb. These signals may help put odors and sounds into new ...
