image: Mating changes the onset of daily activity, masking a central function of the clock. This modulation is mediated by the sex peptide (transferred during copulation) acting on ppk+ neurons, which, in turn, directly contact pdf+ neurons, responsible for the increase of the activity that precedes dawn. Thus, our work identifies a post-mating response directly related to the circadian clock and begins to unravel the underlying neuronal circuit. view more

Sex changes the biological clock of female fruit flies, through a "sex peptide" which is transferred from the male during mating.
