Selected functional processes identified by the DAVID overrepresentation functional clustering algorithm (see Methods) are shown for aging, behavior, and sleep related genes.

The filtered gene list (8080 genes) was used as background, and each of the six gene lists (Up or Downregulated with age; Increased or Decreased as a function of latency in the water maze; Increased or Decreased as a function of active period deep sleep duration) were analyzed separately in the Gene Ontology. A single process (p≤0.05) from each cluster was selected. Abbreviations: GO ID- Gene Ontology Accession ID; CC- cellular component; BP- biological process; MF- molecular function; #- number of genes significant in category; p-value- DAVID statistical test result.
