Hypothesis Formulation for Integrated Neuroendocrinal Mechanisms for Pair Bonding, Romantic Love, Maternal and Paternal Love.

Affiliation, pair bonding and love are important for survival, health and happiness. On the basis of various studies on neural mechanisms, endocrinal and genetic factors involved in various kinds of love, the purpose of this article is to hypothesize comprehensive, integrated neuroendocrinal mechanisms involved in pair bonding, romantic love, maternal and paternal love. The postulation depicted as flow charts at the end of this article seems to be triggered by various factors involving multiple neuroendocrinal mechanisms. It is concluded that the physiological mechanisms involved and the brain areas activated in each of these differ and the representation of postulated comprehensive mechanism in this article is an attempt to add a new dimension to understand the science of a very basic human quality of love.
