▪ Abstract Courtship is a complex behavior in Drosophila that recruits a wide range of genes
for its realization, including those concerning sex determination, ion channels, and circadian …

Genes are understandably crucial to physiology, morphology and biochemistry, but the idea
of genes contributing to individual differences in behaviour once seemed outrageous …

Olfactory systems confer the recognition and discrimination of a large number of structurally
distinct odor molecules. Recent molecular analysis of odorant receptor (OR) genes and …

Biologists postulate that sexual dimorphism in the brain underlies gender differences in
behavior, yet direct evidence for this has been sparse. We identified a male-specific, fruitless …

We determined the cellular substrate for male courtship behavior by quasinatural and
artificial stimulation of brain neurons. Activation of fruitless (fru)-expressing neurons via …

We have evaluated the role of the Drosophila mushroom bodies (MBs) in courtship
conditioning, in which experience with mated females causes males to reduce their …

In 1964, Walter Rothenbuhler proposed a two-gene model to explain phenotypic variance in
the remarkable behavior in which honey bee workers remove dead brood from their …

A regulatory gene, fruitless, appears to be specifically responsible for building the potential
for male sexual behavior into the CNS of Drosophila. We use these and other findings about …

The reproductive biology of Drosophila melanogaster is described and critically discussed,
primarily with regard to genetic studies of sex‐specific behavior and its neural …

In Drosophila melanogaster, antennal hearing organs mediate the detection of conspecific
songs. Combining laser Doppler vibrometry, acoustic near-field measurements and …
