Sleep is Not Just for the Brain: Transcriptional Responses to Sleep in Peripheral Tissues

By using microarrays the authors compared gene expression in tissue from sleep and sleep deprived mice. The results support the notion that the molecular consequences of sleep/wake behavioral state extend beyond the brain to include peripheral tissues. Sleep state induces a highly overlapping response in both heart and lung.
