The neuroendocrine control of the circadian system: adolescent chronotype.

摘要: Scientists, public health and school officials are paying growing attention to the mechanism underlying delayed sleep patterns common in human adolescents. Data suggest that a propensity towards evening chronotype develops during puberty, may be caused by developmental alterations internal daily timekeeping. New support for this theory has emerged from recent studies which show pubertal changes occur many laboratory species similar Using these as models, we find differ sex, internally generated, driven reproductive hormones. These accompanied fundamental properties of circadian timekeeping system, including endogenous rhythm period sensitivity environmental time cues. After comparing progression different species, propose regarding ecological relevance adolescent chronotype, provide suggestions improving
