Resetting the Circadian Clock by Social Experience in Drosophila melanogaster
Joel D. Levine,1Pablo Funes,12Harold B. Dowse,3Jeffrey C. Hall1*
Circadian clocks are influenced by social interactions in a
variety of species, but little is known about the sensory mechanismsunderlying these effects. We investigated whether social cuescould
reset circadian rhythms in Drosophila melanogaster
by addressingtwo questions: Is there a social influence on
circadian timing?If so, then how is that influence communicated? The
experimentsshow that in a social context Drosophila
transmit and receivecues that influence circadian time and that these
cues are likelyolfactory.
