Remarkably and consistent with the original hypothesis of Konopka that I per i SP I 01 i sp is
a null mutant with no biological activity, this mutation creates a stop codon; there is therefore …

Acoustic signals serve communication within and across species throughout the animal
kingdom. Studying the genetics, evolution, and neurobiology of acoustic communication …

It is unclear where in the nervous system evolutionary changes tend to occur. To localize the
source of neural evolution that has generated divergent behaviors, we developed a new …

Deciphering how brains generate behavior depends critically on an accurate description of
behavior. If distinct behaviors are lumped together, separate modes of brain activity can be …

Many animals produce distinct sounds or substrate-borne vibrations, but these signals have
proved challenging to segment with automated algorithms. We have developed …

Behavioral isolation is a potent barrier to gene flow and a source of striking diversity in the
animal kingdom. However, it remains unclear if the linkage disequilibrium (LD) between sex …

The neural basis for behavioural evolution is poorly understood. Functional comparisons of
homologous neurons may reveal how neural circuitry contributes to behavioural evolution …

The courtship song of male Drosophila melanogaster is generated by wing vibration and
contains an interpulse interval (IPI) which is species-specific and usually falls in the mean …

The clock gene period (per) is a regulator of circadian rhythms but may also play a role in
the regulation of ultradian rhythms, such as insect courtship. Males of the parasitoid wasp …

From 1980 to 1991, Kyriacou, Hall, and collaborators (K&H) reported that the Drosophila
melanogaster courtship song has a 1-min cycle in the length of mean interpulse intervals …
