Hibernation has been suggested to cause sleep debt, and since oleamide is elevated in the central nervous system of sleep-deprived mammals we hypothesized that brains from hibernating mammals would contain more oleamide than those that were not hibernating. Oleamide was 2.6-fold greater in brains of hibernating Richardson's ground squirrel (Spermophilus richardsonii) than in euthermic brains. Additionally, brain fatty acid-binding protein did not bind oleamide and does not represent a solubilized pool of oleamide.
