Vasopressin, oxytocin and social behaviour.
Understanding the neurobiology of social behaviour in mammals has been considerably advanced by the findings from two species of vole, one of which is monogamous and pair bonds whereas the other species is promiscuous and fails to form any long-lasting social relationships. The combination of neurobehavioural studies and molecular genetics has determined behavioural differences between the two ...
متن کاملHormones and sexual behaviour.
Despite new technological advances and improved assay methods, the relationship between hormones and human sexual behavior is still poorly understood. Sex drive and responsiveness, gender identification, and sexual preference are all influenced by hormones. Endocrine studies of impotent men have produced conflicting results. Exogenous androgens seem to produce some results with impotent men....
متن کاملSexual behaviour: Secrets and flies
Recent studies of Drosophila courtship mutants provide a molecular foundation for sexual orientation and behaviour.
متن کاملOxytocin signal and social behaviour: comparison among adult and infant oxytocin, oxytocin receptor and CD38 gene knockout mice.
Oxytocin in the hypothalamus is the biological basis of social recognition, trust, love and bonding. Previously, we showed that CD38, a proliferation marker in leukaemia cells, plays an important role in the hypothalamus in the process of oxytocin release in adult mice. Disruption of Cd38 (Cd38 (-/-)) elicited impairment of maternal behaviour and male social recognition in adult mice, similar t...
متن کاملSexual behaviour: Courting dissatisfaction
A nuclear receptor, the product of the dissatisfaction gene, has been found to regulate Drosophila sexual behaviour, probably via its action in a small subset of neurons. The results shed new light on the genetic determination of sexual behaviour.
