Corticotropin-releasing factor induces social preferences in male prairie voles.
Exposure to stressors facilitates the formation of social preferences in monogamous male prairie voles (Microtus ochrogaster). In the present study, the hypothesis was tested that treatment with corticotropin-releasing factor (CRF), a neuropeptide released during stress, is capable of inducing social preferences in male prairie voles. The effects of five doses of CRF (0.01, 0.1, 1.0, 10 and 100...
متن کاملAnorectic actions of prolactin-releasing peptide are mediated by corticotrophin-releasing hormone receptors
Prolactin-releasing peptide and corticotrophin-releasing hormone R-00402-2003.R1 2 Prolactin-releasing peptide (PrRP) reduces food intake and body weight, and modifies body temperature when administered centrally in rats, suggesting a role in energy homeostasis. However, the mediators of PrRP's actions are unknown. The present study, therefore, firstly examined the possible involvement of the a...
متن کاملPhotoperiod affects the gonadotropin-releasing hormone neuronal system of male prairie voles (Microtus ochrogaster).
In order to maximize survival, animals inhabiting temperate and boreal latitudes exhibit numerous adaptations to changing seasons. Central among this suite of coping strategies is the cessation of breeding during the suboptimal conditions of winter. Many nontropical rodents inhibit reproduction well in advance of winter in response to short day lengths. Male prairie voles (Microtus ochrogaster)...
متن کاملFood restriction affects the gonadotropin releasing hormone neuronal system of male prairie voles (Microtus ochrogaster).
Individuals of species inhabiting temperate and boreal latitudes optimize the timing of energetically costly processes by curtailing nonessential energetically demanding processes when environmental conditions are not favourable. One proximate environmental variable used to fine-tune moment-to-moment changes in reproductive physiology and behaviour is food intake. The neuroendocrine mechanisms ...
متن کاملSocial environment regulates corticotropin releasing factor, corticosterone and vasopressin in juvenile prairie voles.
Stressful social conditions, such as isolation, that occur during sensitive developmental periods may alter present and future social behavior. Changes in the neuroendocrine mechanisms closely associated with affiliative behaviors and stress reactivity are likely to underlie these changes in behavior. In the present study, we assessed the effects of post-weaning social housing conditions on the...
