One of the best known researchers in this area is Helen Fisher of Rutgers University in New Jersey. In highly social species such as prairie voles (Kenkel et al., 2013), and presumably in humans, the intricate molecular dances of oxytocin and vasopressin fine-tune the coexistence of caretaking and protective aggression. Peggy LaCerra has studied cognitive neuroscience to develop her theories about the evolution of the human mind.

When it comes to love it seems we are at the mercy of our biochemistry. Predictably, when isolated voles were given additional exogenous oxytocin, this treatment did restore many of these functions to normal (Grippo, Trahanas, Zimmerman, Porges, & Carter, 2009). Chemicals of love: Attachment: Oxytocin: Released by the hypothalamus gland during child birth and also helps the breast express milk. DeVries, A. C., DeVries, M. B., Taymans, S. E., & Carter, C. S. (1996). Date Night Chemicals. Although research has only begun to examine the physiological effects of these peptides beyond social behavior, there is a wealth of new evidence showing that oxytocin can influence physiological responses to stress and injury. Oxytocin attenuates NADPH-dependent superoxide activity and IL-6 secretion in macrophages and vascular cells. Based on research in rats, it seems that in response to adverse early experiences of chronic isolation, the genes for vasopressin receptors can become upregulated (Zhang et al., 2012), leading to an increased sensitivity to acute stressors or anxiety that may persist throughout life. Perhaps in part. Although evidence exists for the healing power of love, only recently has science turned its attention to providing a physiological explanation for love. Attraction, love and relationships are fueled by actual chemicals, well, who hasn't heard that line nowadays? The Chemistry of Love.info.

The evolutionary pathways that led from reptiles to mammals allowed the emergence of the unique anatomical systems and biochemical mechanisms that enable social engagement and selectively reciprocal sociality. endobj Genes involved in convergent evolution of eusociality in bees. Lesions in various bodily tissues, including the brain, heal more quickly in animals that are living socially versus in isolation (Karelina & DeVries, 2011). ��h�'�Q��~v}��4��F�0,k���&QRػ�3_ G/�-��,��y���� �%>!W�BӇ�.|�TYH�$Yfݴ��"�$����Ư��Բ�$��y� %_�4�L��0�YO������zK�[_�)��ѫZ�%�X�t����I�ଛ;i3̪�LO54mqxmv��;�i�e[�:YۭŒI'�3�Bג���\�x�[�X:V�O�:acg����ۛ�ۥ�I�X��o6�dd�Z�4�l��ܪ��yX֏I,�Cl���+n�"�Fo�eX�;��&`����l����>�jL�,���yap�YW̊,aR9�b��3gq.
