英文摘要
The main goals of the proposed research are to characterize the
neuroendocrine substrates involved in generation of circannual
rhythms in behavior and physiology, and to identify environmental
stimuli that synchronize these endogenous rhythms. The model
species to be studied is the golden-mantled ground squirrel.
Specific projects include: 1) A definitive test of the role of day
length in entrainment of circannual rhythms, 2) establishing the
role of the retinohyothalamic tract in photic entrainment of
circannual rhythms, 3) determining if the lateral septal nuclei,
medial pre-optic region and mammillary nuclei are part of the
neural substrate for generation and expression of circannual
rhythms, 4) establishing whether the period of circadian rhythms
is temperature-dependent during part of the circannual cycle, 5)
evaluating interactions among body fat, energetics and
reproduction during the circannual cycle, and, 6) establishing the
sequence of lipid mobilization from different fat depots during
the weight loss phase of the circannual cycle, as well as
differences between juveniles and adults in number and size of
adipocytes. Parameters to be measured include body mass,
adipocyte number and size, plasma testosterone levels, circadian
activity rhythms, and external reproductive condition. The
proposed work is relevant to mechanisms that underlie endogenous
seasonal affective disorders in human beings, and could ultimately
lead to pharmacological as well as non-invasive treatments for
these conditions.
