A new study finds poor air quality is linked to a heightened risk for depression. Depression is a classified as a mood ...

A new Drosophila collection of Parkinsonism models reveals early synaptic cholinergic projection neuron dysfunction, linking synaptic failure to later dopaminergic decline, highlighting a role for ...

Early research had suggested that each neuron expresses just one type of receptor, and that all the neurons expressing a particular receptor link to a dedicated olfactory nerve cluster (called a ...

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 ...

The researchers wanted to learn three things from their study of the two groups: the levels of degeneration (damage) of neurons in the olfactory system, the number of olfactory axons lost ...

"To analyze how the amygdala functions during depression, we measured the activity of some networks of neurons involved in the more or less negative interpretation of olfactory stimuli," says Alonso.

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 ...
