Gonadal hormone effects on entrained and free-running circadian activity rhythms in the developing diurnal rodent Octodon degus.The slowly maturing, long-lived rodent Octodon degus (degu) provides a unique opportunity to examine the development of the circadian system during ...

Development of the chorioallantoic placenta in Octodon degus--a model for growth processes in caviomorph rodents?The degu Octodon degus is one of the very few members of caviomorph or hystricognath Rodentia that possesses a simply arranged chorioallantoic placenta ...

Period gene expression in the diurnal degu (Octodon degus) differs from the nocturnal laboratory rat (Rattus norvegicus).of Per1 and Per2 mRNA in the SCN and putative striatum and cortex of Octodon degus (degu), a diurnal hystricognath rodent, with those of the ...
