Scientists, public health and school officials are paying growing attention to the mechanism
underlying the delayed sleep patterns common in human adolescents. Data suggest that a …

The discovery that kisspeptin was critical for normal fertility in humans ushered in a new
chapter in our understanding of the control of GnRH secretion. In this paper, we will review …

Social isolation is considered a stressful situation that results in increased physiological
reactivity to novel stimuli, altered behaviour, and impaired brain function. Here, we …

Social isolation in adulthood is a psychosocial stressor that can result in endocrinological
and behavioral alterations in different species. In rodents, controversial results have been …

Estradiol influences the level and distribution of daily activity, the duration of the free-running
period, and the behavioral phase response to light pulses. However, the mechanisms by …

Female phenotypic masculinization is a phenomenon widely described among mammals. In
species that produce litters, female masculinization occurs in utero during late trimester of …

During puberty, human adolescents develop a later chronotype, exhibiting a delay in the
timing of rest and activity as well as other daily physiological rhythms. The purpose of this …

Maturation of the forebrain involves transitions from higher to lower levels of synaptic
plasticity. The timecourse of these changes likely differs between regions, with the …

There are sex differences in free‐running rhythms, activity level and activity distribution that
are attributed, in part, to the action of gonadal hormones. We tested the hypothesis that non …

Homophily by morphological and behavioral traits has been described in several species of
vertebrates, but its functional consequences remain poorly studied. Homophily by plurally …
