Use-Dependent Plasticity Regulates Sleep Need In Drosophila Melanogaster, Jeffrey Donlea Jan 2010

Use-Dependent Plasticity Regulates Sleep Need In Drosophila Melanogaster, Jeffrey Donlea

All Theses and Dissertations (ETDs)

Although the necessary functions of sleep have not been identified, sleep has been shown to play an important role in the consolidation of memories. Recent studies have shown that, in addition to playing a strong role in sleep regulation, the circadian clock also influences processes associated with learning and memory. Thus, the neural circuits that control circadian rhythms are uniquely positioned to play an important role in coordinating interactions between sleep and memory. Drosophila melanogaster exhibit increased sleep following several days of social experience and require sleep to consolidate long-term memories: LTM) after Courtship Conditioning, an associative memory assay. We …

In educational contexts, tests not only assess what students know, they can also directly improve long-term retention of subject matter relative to restudying it. More importantly, the memorial advantage of testing is not limited to select information that was tested earlier. Research has shown that testing can serve as a versatile learning tool by enhancing the long-term retention of non-tested information that is conceptually related to previously tested information; stimulating the subsequent learning of new information; and permitting better transfer of learning to new knowledge domains. We further investigated the potential benefits of testing on learning by asking whether testing …
