A powerful new technique for visualizing neurons in the fly brain has uncovered fine neuroanatomical differences between the olfactory circuitries of male and female Drosophila.

Stop and Smell the Roses: Inostensible Propositional Knowledge and Raising the Standard of Knowing

Learning to Smell the Roses: Experience-Dependent Neural Plasticity in Human Piriform and Orbitofrontal Cortices

It is widely presumed that odor quality is a direct outcome of odorant structure, but human studies indicate that molecular knowledge of an odorant is not always sufficient to predict odor quality. Indeed, the same olfactory input may generate different odor percepts depending on prior learning and experience. Combining functional magnetic resonance imaging with an olfactory paradigm of percept...

The sense of smell is mediated by GPCRs in the odorant receptor (OR) family. Greer et al. report a new family of odor detectors, MS4As, that have similar cellular localization and chemodetection ability as ORs but are not GPCRs and follow a strikingly different logic of odor coding at the periphery.
