Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.

Single-cell transcriptomes of olfactory receptor neurons at multiple developmental stages reveal cell-type-specific gene expression programs that underlie their development and sensory biology.

G protein-coupled odorant receptors regulate their own gene transcription based on their cell surface trafficking, which is facilitated by receptor transporting protein (RTP) family members.

A model of efficient coding by olfactory neurons explains context-dependence observed in the effect of perturbations to the olfactory environment.

A morphological characterization of Drosophila olfactory receptor neurons—conducted systematically at nanoscale resolution—yields an extensive morphometric dataset, identifies novel features of olfactory sensilla, and raises intriguing questions for how the size and shape of sensory neurons influence their function.

Olfactory receptor neurons adapt to odorant mean and variance and use complementary kinetics to preserve the timing of odorant encounters, despite adaptation slowing down transduction.

Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.

Computational and theoretical analyses offer novel and unexpected insight into how complex, naturally occurring odor mixtures are parsed and normalized at the very first stage of olfaction.

Muscarinic acetylcholine receptor type A in adult Drosophila inhibits Kenyon cells, and is required for aversive olfactory learning and learning-associated synaptic depression between Kenyon cells and their output neurons.

The neuronal composition of a mouse’s nose is individually unique due to a combination of olfactory experience and genetic variation local to olfactory receptor genes.
