Restricted feeding schedules phase shift daily rhythms of c-Fos and protein Per1 immunoreactivity in corticolimbic regions in rats

Present data indicate that cellular activation of corticolimbic structures is associated with behavioral events related to food anticipatory activity and that mealtime is a relevant signal that shifts daily oscillations of PER1 in corticolimbic structures. Data suggest a relevant role of corticolimbic structures as oscillators for FAA.
