Yes, we have been through all that sweetness overload we experience during V-Day where our timelines are flooded with flowers and expressions of undying love.
In the terrain of the human heart, scientists tell us, at least three independent but interrelated brain systems are at play, all moving us in their own way. To untangle love's mysteries, neuroscience distinguishes between neural networks for attachment, for caregiving, and for sex. Each is fueled by a different set of brain chemicals and hormones, and each runs through a disparate neuronal circuit. Each adds it own chemical spice to the many varieties of love.
Attachment determines who we turn to for succor; these are the people we miss the most when they are absent. Caregivers gives us the urge to nurture the people for whom we feel most concern. When we are attached, we cling; when we are caregiving we provide. And sex is, well sex.
Sex begins the job of continuing the species. Attachment provides the glue that keeps not just a couple but a family together and caregiving adds the impulse to look after the offspring, so our children can grow up to have their own.
When attachment entwines with caring and sexual attraction, we can savor full-blown romance.
