Sister projection neurons in the mammalian olfactory system do not share sensory synaptic input indicating that lineage-independent mechanisms regulate their synaptic connectivity with the olfactory sensory neurons.

Several neuronal subtypes found in the early zebrafish olfactory placode are not derived from the neural crest, as previously thought, but from the preplacodal ectoderm.

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

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.

While both implicit and explicit learning augment neurogenesis, adult-born cells differ in their morphology, functional coupling and inhibitory action impacting differentially the olfactory bulb output.

Habituation to brief olfactory stimulation is biphasic and mediated by distinct neuronal circuits where an initial latency phase is rapidly followed by stimulus devaluation signifying behavioral habituation in Drosophila.

Adult-born neurons in the olfactory bulb allow state-dependent pattern separation of representations of similar odorants.

Individual neurons of ventral tenia tecta which is a part of olfactory cortex tune to specific time windows in the behavioral context during odor-guided goal-directed behaviors.

The nonsense-mediated RNA decay (NMD) branch-specific factor UPF3B influences olfactory sensory neuron cell populations, the olfactory receptor repertoire, and antimicrobial gene expression.

Genetic and behavior analyses show that Caenorhabditis nematodes are lured to the predator Arthrobotrys oligospora by olfactory mimicry of food and sex cues.
