A Circadian Clock in the Olfactory Bulb Anticipates Feeding during Food Anticipatory Activity
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 information about properties of the food, one of them being the olfactory system, which has received little attention in relation to synchronization by food. In addition, the olfactory bulb has a circadian pacema...
متن کاملA circadian clock in the olfactory bulb controls olfactory responsivity.
Recently, it has been shown that multiple mammalian cell types express daily rhythms in vitro. Although the suprachiasmatic nucleus (SCN) of the hypothalamus is known to regulate a wide range of circadian behaviors, the role for intrinsic rhythmicity in other tissues is unknown. We tested whether the main olfactory bulb (OB) of mice mediates daily changes in olfaction. We found circadian rhythm...
متن کاملDaily rhythms of food-anticipatory behavioral activity do not require the known circadian clock.
When food availability is restricted to a particular time each day, mammals exhibit food-anticipatory activity (FAA), a daily increase in locomotor activity preceding the presentation of food. Considerable historical evidence suggests that FAA is driven by a food-entrainable circadian clock distinct from the master clock of the suprachiasmatic nucleus. Multiple food-entrainable circadian clocks...
متن کاملCircadian Regulation of Food-Anticipatory Activity in Molecular Clock–Deficient Mice
In the mammalian brain, the suprachiasmatic nucleus (SCN) of the anterior hypothalamus is considered to be the principal circadian pacemaker, keeping the rhythm of most physiological and behavioral processes on the basis of light/dark cycles. Because restriction of food availability to a certain time of day elicits anticipatory behavior even after ablation of the SCN, such behavior has been ass...
متن کاملP11: Assess the Electrophysiological Activity of Olfactory Bulb in the Animal Model of PTSD and its Relationship with Neuroinflammation in the Olfactory Bulb
Post-traumatic stress disorder (PTSD) is a mental health condition that's triggered by a terrifying event - either experiencing it or witnessing it. In addition to the relationship between PTSD and neuroinflammation, research indicates that olfactory bulb are effective in anxiety disorders. The aim of this study was to assess the electrophysiological activity of olfactory bulb in the animal mod...
