The complete neural circuit map of a tractable olfactory system will support studies towards bridging the gap between circuits and behavior.

Human primary olfactory cortical regions can be parcellated into anatomically distinct areas based on whole-brain functional connectivity profiles, suggesting distinct, parallel functional pathways in the human olfactory system.

Silkmoth utilizes multimodal information to modulate behavior according to the degree of turbulence in the environment, enabling it to efficiently an odor source search.

Vax1 suppresses dopaminergic neuron phenotype by inhibiting Pax6 expression in the subventricular zone of the lateral ventricle and is necessary to generate Calbindin interneurons for the postnatal olfactory bulb.

Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

Semiochemicals activate a subpopulation of sexually dimorphic olfactory sensory neurons.

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

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.

Phototaxis and courtship behavioral preferences reflect strong correlation with differences in olfactory and visual nervous system investment across five monophyletic Drosophila species, and could help explain their speciation events.
