The orexigenic peptide ghrelin stimulates both food intake and growth hormone release and is synthesized in the stomach and in hypothalamic areas involved in feeding control. The suprachiasmatic nuclei of the hypothalamus (SCN) control most circadian

Circadian rhythms are internally generated circa 24 h rhythms. The phase of the circadian pacemaker in mammals can be adjusted by external stimuli such as the daily cycle of light, as well as by internal stimuli such as information related to the phy

Neuropeptide Y (NPY) is delivered to the suprachiasmatic nuclei (SCN) circadian pacemaker via an input from the thalamic intergeniculate leaflet. NPY can inhibit light-induced responses of the circadian system of Syrian hamsters. Here we studied whet

We studied whether access to a novel running wheel in vivo could reset the suprachiasmatic nuclei (SCN) in vitro. Golden hamsters were transferred to dim red light at Zeitgeber time (ZT) 4, given their first exposure to a running wheel for 3 h, and k

The present review examine the role of neuropeptide (NPY) in the circadian system, focusing on the interactions between light and NPY, especially during the subjective night. NPY has two different effects on the circadian system of mammals. On one ha

The aim of the present work is to discuss the available data on neonatal and adult antidepressant treatment in relation to animal models of depression and serotonergic modulation of the circadian system, with a particular emphasis on our own publishe

Neurochemical events leading to photic entrainment of circadian rhythms are reviewed. This entrainment pathway includes the retinohypothalamic tract and a glutamate-NMDA receptor (among others) interaction in the suprachiasmatic nuclei (SCN). The mod

Day-night differences in locomotor and anxiety-related behavior and brain serotonin metabolism were examined in adult Syrian hamsters that received clomipramine (15 mg/kg) or vehicle from day 8 to day 21 of life. Locomotor activity was significantly

Golden hamsters (young: 3 month-old; old: more than 12 month-old; or neonatally treated with clomipramine – a serotonin/noradrenaline re-uptake inhibitor antidepressant) were initially entrained to a 14:10 light:dark cycle, and their reentrainment

The circadian behavior of male Syrian hamsters injected with the serotonin/norepinephrine reuptake inhibitor clomipramine (15 mg/kg from postnatal days 8 to 21) was examined. Clomipramine treatment significantly augmented mean activity values of whee
