Love forms the theme of various poems, plays, historic as well as contemporary literature, and is glorified in art and music, deliberated upon in speeches, celebrated on the silver-screen. Nevertheless, the scientific basis of love remains wrapped in mysticism although there have been advances in pinpointing the hormones, neurotransmitters, and more recently the anatomical pathways that play a role in love, with evidence in imaging modalities. We aim at demystifying the role, function, and workings of love and its counterparts—intimacy, attraction, attachment, and sensuality—in this review.
