Phenylethylamine – love, hormons, sex

Summary/Abstract: Love is probably the most popular subject of many fields of art, however, attempt to explain this phenomenon brings still no clear picture to the world of science. Knowing that sexual responses depend on the effects of neurotransmitters acting at the level of central nervous system, we can assume that all the “magic” of love is only chemistry of the very complex biological reactions. The most often mentioned substances responsible for the euphoria accompanying infatuation are phenylethylamine, dopamine and norepinephrine, and for subsequent attachment to the partner oxytocin and serotonin. Central dopaminergic system affected by PEA is a key element of sexual behavior control. Nucleus accumbens and striatum, as components of the limbic system display great ratio between the action of PEA on dopaminergic transmission and behavioral effects. PEA modulates dopaminergic,andrenergic transmission and has possible impact on oxytocin excretion. These processes occur in intra-and extracellular spaces and take into account the density of receptors and sophisticated intracellular effector proteins response. The idea of __assigning the properties of generating feelings to a single substance, represents a major simplification. Love should be considered as a dynamic process, in which the successive steps involve different hormones and neurotransmitters. Scientific description of love, if only possible, requires further exploration of connexions between various neurotransmitters and their effects on neuronal transmission in specific brain centers.
