Sleep contributes to preference for novel food odours in Drosophila melanogaster

Abstract The importance of sleep in maintaining cognitive functions such as learning and memory has been reported in both vertebrates and invertebrates. Previous studies demonstrated that sleep deprivation impaired the olfactory memory retention of fruit flies as described in the classical condition...

description	Abstract The importance of sleep in maintaining cognitive functions such as learning and memory has been reported in both vertebrates and invertebrates.
