▪ 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 …

Mating affects the reproductive behaviour of insect females: the egg-laying rate increases
and courting males are rejected. These post-mating responses are induced mainly by …

The mushroom body (MB) is an important centre for higher order sensory integration and
learning in insects. To analyse the development and organisation of the MB neuropile in …

Memories are thought to be due to lasting synaptic modifications in the brain. The search for
memory traces has relied predominantly on determining regions that are necessary for the …

Sleep is one of the few major whole-organ phenomena for which no function and no
underlying mechanism have been conclusively demonstrated. Sleep could result from …

The mushroom body is required for a variety of behaviors of Drosophila melanogaster.
Different types of intrinsic and extrinsic mushroom body neurons might underlie its functional …

We have isolated a new Drosophila mutant, satori (sat), the males of which do not court or
copulate with female flies. The sat mutation comaps with fruitless (fru) at 91B and does not …

Although the importance of the Drosophila mushroom body in olfactory learning and
memory has been stressed, virtually nothing is known about the brain regions to which it is …

Octopamine is a neuromodulator that mediates diverse physiological processes in
invertebrates. In some insects, such as honeybees and fruit flies, octopamine has been …

The Drosophila roX1 gene is X-linked and produces RNAs that are male-specific, somatic,
and preferentially expressed in the central nervous system. These RNAs are retained in the …
