The Pathology of Love The unpalatable truth is that falling in love is, in some ways, indistinguishable from a severe pathology. Behavior changes are reminiscent of psychosis and, biochemically speaking, passionate love closely imitates substance abuse. Appearing in the BBC series Body Hits on December 4, Dr. John Marsden, the head of the British National Addiction Center, said that love is addictive, akin to cocaine and speed. Sex is a "booby trap", intended to bind the partners long enough to bond.Functional Magnetic Resonance Imaging (fMRI), showed that the same areas of the brain are active when abusing drugs and when in love. The prefrontal cortex - hyperactive in depressed patients - is inactive when besotted. Helen Fisher of Rutger University suggests a three-phased model of falling in love. Each stage involves a distinct set of chemicals. The BBC summed it up succinctly and sensationally: "Events occurring in the brain when we are in love have similarities with mental illness".Moreover, we are attracted to people with the same genetic makeup and smell (pheromones) of our parents. Dr Martha McClintock of the University of Chicago studied feminine attraction to sweaty T-shirts formerly worn by males. The closer the smell resembled her father's, the more attracted and aroused the woman became. Falling in love is, therefore, an exercise in proxy incest and a vindication of Freud's much-maligned Oedipus and Electra complexes.It is telling that once attachment is formed and infatuation gives way to a more stable and less exuberant relationship, the levels of these substances return to normal. They are replaced by two hormones (endorphins) which usually play a part in social interactions (including bonding and sex) - Oxytocin (the "cuddling chemical") and Vasopressin. Oxytocin facilitates bonding. It is released in the mother during breastfeeding, in the members of the couple when they spend time together - and when they sexually climax.Still, love cannot be reduced to its biochemical and electrical components. Love is not tantamount to our bodily processes - rather, it is the way we experience them. Love is how we interpret these flows and ebbs of compounds using a higher-level language. In other words, love is pure poetry.
