The aim of this study was to examine whether histamine mediates its effects on the circadian system through Hrh1 or Hrh3 receptors. We assessed both diurnal and free-running locomotor activity rhythms of Hrh1(-/-) and Hrh3(-/-) mice. We also determined the expression of Per1, Per2 and Bmal1 genes in the suprachiasmatic...
