Abstract

Anticipatory activity for daily chocolate chip access is stronger than that for daily peanut butter access. Mice given daily chocolate chip access, but not peanut butter access, exhibited altered circadian organization among peripheral clocks. During food deprivation, mice exhibited anticipatory food-seeking behavior at the time they had previously been given chocolate chip access, suggesting that the time of palatable meals is encoded in the circadian pacemaker controlling food-anticipatory activity.
