Here we review the neurobiology of infant odor learning in rats, and discuss the unique role
of the stress hormone corticosterone (CORT) in the learning necessary for the developing …

Daily variations in behaviour and physiology are controlled by a circadian timing system
consisting of a network of oscillatory structures. In mammals, a master clock, located in the …

Ghrelin, an orexigenic hormone produced by the stomach, is secreted in anticipation of
scheduled meals and in correlation with anticipatory locomotor activity. We hypothesized …

Circadian rhythms in mammals are regulated by a light‐entrainable circadian pacemaker in
the hypothalamic suprachiasmatic nucleus and food‐entrainable oscillators located …

This article is part of a Special Issue “Parental Care”. Jay Rosenblatt effectively promoted
research on rabbit maternal behavior through his interaction with colleagues in Mexico …

Food‐anticipatory activity (FAA) and especially the food‐entrained oscillator (FEO) have
driven many scientists to seek their mechanisms and locations. Starting our research on FAA …

Mother rabbits nurse their young once a day with circadian periodicity. Nursing bouts are
brief (ca. 3 min) and occur inside the maternal burrow. Despite this limited contact mother …

Circadian rhythms are 24 h cycles of behavior, physiology and gene expression that function
to synchronize processes across the body and coordinate physiology with the external …

Rabbit pups ingest food, in this case milk, once a day with circadian periodicity and are a
natural model of food anticipatory activity. During nursing, several sensory systems receive …

Nursing in the rabbit is under circadian control, and pups have a daily anticipatory
behavioral arousal synchronized to this unique event, but it is not known which signal is the …
