Serotonergic cells innervating the Drosophila antennal lobe are inhibited by odors and modulate olfactory responses in conjunction with the entire serotonergic network.

FIB-SEM is used to identify comprehensively and reconstruct 192 neurons and their complete connectome for glomerulus VA1v of the Drosophila antennal lobe, in particular to reconstruct its local interneurons.
A comprehensive synapse-level analysis of a fly central-brain region has led to the identification of molecules that are necessary for mediating the normal density of connections.
Neurons in the fruit fly olfactory system respond most strongly to the sudden appearance of an odor, and to odors that are changing rapidly in strength, but are relatively insensitive to the absolute levels of an odor.
Advanced genetics and imaging reveal wiring logic underlying the olfactory map organization in the developing fruit fly brain, and strategies employed by projection neurons to target dendrites to specific locations in a timely manner.

Chronic stimulation with odors at naturally occurring concentrations only mildly impacts early stages of olfactory processing, suggesting a need to re-interpret prevailing models of how chronic odor exposure affects olfactory function.

The sense of smell of female hawkmoths has evolved to find the intense odor of floral nectar sources as well as inconspicuous scents of oviposition sites within a complex olfactory landscape.
Genetic variation in a biogenic amines receptor underlies a means of gain control for nonassociative learning and hence an important form of attention that is the basis for tradeoffs in foraging in a social collective.
