The organization of olfactory projection neurons and their synaptic connectivity with third-order neurons studied along with olfactory responses suggest that the labeled-line design is partially at work in the Drosophila olfactory system.

Women with unexplained miscarriages have an altered behavioral and brain response to men's body-odor, and this may reflect a factor in their condition.

Dopamine novelty signals are localized in the posterior tail of the striatum along with general salience signals, while dopamine in the ventral striatum reliably encodes reward prediction error.

The odor-elicited responses of olfactory receptor neurons consist of a discrete set of four spike pattern motifs, each with distinct adaptation properties, together amplifying distinctions between similar and temporally complex chemical inputs such as odor plumes.

To study odor-guided navigation of small animals such as worms and fly larvae, a novel flow chamber and odor sensor array are presented that better characterize the odors that the animal experiences.

The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.

The lateral horn can be classified into three functional odor response domains that decode opposing hedonic valences and odor intensity.

Drosophila flies infer value to olfactory stimuli based on the previously repeatedly presented associative structure between two odorants.

A large interneuron in the Drosophila mushroom body has compartmentalized activity, which causes localized inhibition and predicts that Kenyon cells inhibit themselves more than they inhibit other individual Kenyon cells.

NMDA-spikes mediate plasticity of lateral olfactory tract inputs carrying direct odor information to the piriform cortex.
