Scott F, Belle M, Delagrange P, Piggins H
J Neuroendocrinol
. 2010 Sep;
22(11):1148-56.
PMID: 20819119
The master circadian pacemaker in the suprachiasmatic nuclei (SCN) regulates the nocturnal secretion of the pineal hormone melatonin. Melatonin, in turn, has feedback effects on SCN neuronal activity rhythms via...

J Biol Rhythms
. 2010 Aug;
25(4):235-46.
PMID: 20679493
Daily exercise promotes physical health as well as improvements in mental and neural functions. Studies in intact wild-type (WT) rodents have revealed that the brain's suprachiasmatic nuclei (SCN), site of...

Guilding C, Hughes A, Piggins H
Neuroscience
. 2010 Jun;
169(4):1630-9.
PMID: 20547209
The habenula complex is implicated in a range of cognitive, emotional and reproductive behaviors, and recently this epithalamic structure was suggested to be a component of the brain's circadian system....

Brown T, Piggins H
J Biol Rhythms
. 2009 Feb;
24(1):44-54.
PMID: 19227579
The coordinated activity of thousands of cellular oscillators in the suprachiasmatic nuclei (SCN) temporally regulates mammalian physiology to anticipate daily environmental changes across the seasons. The phasing of clock gene...

Brown T, Coogan A, Cutler D, Hughes A, Piggins H
Neurosci Lett
. 2008 Nov;
448(3):273-8.
PMID: 18973790
The study of neural arousal mechanisms has been greatly aided by the discovery of the orexin peptides (orexin A and orexin B), the subsequent identification of the neurons that synthesize...

Hughes A, Piggins H
J Biol Rhythms
. 2008 May;
23(3):211-9.
PMID: 18487413
Vasoactive intestinal polypeptide and its receptor, VPAC2, play important roles in the functioning of the dominant circadian pacemaker, located in the hypothalamic suprachiasmatic nuclei (SCN). Mice lacking VPAC2 receptors (Vipr2-/-)...

Brown T, McLachlan E, Piggins H
Neuroscience
. 2008 May;
154(2):839-47.
PMID: 18479832
Neuropeptide signaling plays key roles in coordinating cellular activity within the suprachiasmatic nuclei (SCN), site of the master circadian oscillator in mammals. The neuropeptide angiotensin II (ANGII) and its cognate...

J Evol Biol
. 2007 Aug;
20(5):1998-2004.
PMID: 17714316
In species where parents may commit infanticide, temporal kin recognition can help ensure parents kill unrelated young but care for their own offspring. This is not true recognition, but rather...

J Neurophysiol
. 2006 Dec;
97(3):2553-8.
PMID: 17151217
Vasoactive intestinal polypeptide (VIP), acting via the VPAC(2) receptor, is a key signaling pathway in the suprachiasmatic nuclei (SCN), the master clock controlling daily rhythms in mammals. Most mice lacking...

Am J Physiol Regul Integr Comp Physiol
. 2005 Oct;
290(3):R785-92.
PMID: 16239370
Circadian rhythms of animals are reset by exposure to light as well as dark; however, although the parameters of photic entrainment are well characterized, the phase-shifting actions of dark pulses...
