Unexplained repeated pregnancy loss is associated with an altered perception of male odors and differences in brain regions that process smells.

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.

Impact of odor experience on myeloid metabolism and immunity.

A combination of genetic, anatomical and physiological techniques has revealed that the lateral horn, a region of the brain involved in olfaction in flies, has many more types of neurons than expected.

Of the 50 primary olfactory channels in vinegar flies, only 10 drive avoidance or approach behavior when activated by themselves, indicating that most olfactory responses are multi-channel responses that follow complex combination rules.

Responses to odour mixtures are more discriminable in awake, behaving mice due to a combination of dampened responses keeping responses in the linear range and pattern decorrelation, with these two mechanisms operating on different timescales.

Synaptic resolution analysis of a full olfactory connectome reveals lateralised circuits, convergence of innate and learned pathways, and shows that homologous neurons are highly stereotyped within and across brains.

To track odors borne on turbulent airflow, mice strategically follow their nose, with sampling movements and sensory computations reminiscent of those demonstrated in nematodes and insects.

Computational analyses of in-vivo cerebral activity show that gamma oscillations in the olfactory cortex originate from local feedback inhibition following each sniff and serve to segregate competing odor representations through a winner-take-all process, providing an optimal window to decode odor.
