The generation and systematic characterisation of driver lines labelling a large number of neurons in the Drosophila innate olfactory processing centre bridges electron microscopy neuronal reconstructions, circuits and behaviour.

The lateral horn can be classified into three functional odor response domains that decode opposing hedonic valences and odor intensity.

Adult neurogenesis, although happening at a slow rate in the adult brain, plays an important role in learning and memory and has the ability to powerfully modulate large scale neural networks.

The Drosophila lateral horn, a higher olfactory brain area, contains >165 genetically defined cell types with stereotyped odour responses across animals and improved odor categorisation compared with their inputs.

A combination of genetic, anatomical and physiological techniques has revealed that the lateral horn, a region of the brain involved in olfaction in flies, has many more types of neurons than expected.

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.

Reproductive fluids help the correct establishment of some epigenetic marks and gene expression in preimplantation pig embryos.

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.

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

Genomic analyses provide new insights into natural history and pathogenesis of cytomegalovirus infection and suggest new testable hypotheses that could be important for the design and implementation of new vaccines.
