Waking Experience Affects Sleep Need in Drosophila
Indrani Ganguly-Fitzgerald,1*Jeff Donlea,2Paul J. Shaw2
Sleep is a vital, evolutionarily conserved phenomenon, whosefunction is unclear. Although mounting evidence supports a rolefor sleep in the consolidation of memories, until now, a molecularconnection between sleep, plasticity, and memory formation hasbeen difficult to demonstrate. We establish Drosophila as amodel to investigate this relation and demonstrate that theintensity and/or complexity of prior social experience stablymodifies sleep need and architecture. Furthermore, this experience-dependentplasticity in sleep need is subserved by the dopaminergic andadenosine 3',5'-monophosphate signaling pathways and a particularsubset of 17 long-term memory genes.
