In the introduction of their paper, Helen E. Fisher et al [1] cite the results of a previous study using functional magnetic resonance imaging (fMRI) of people in a happy love relationship and the conclusion of that study, saying that the state of falling in love is a goal-directed motivational state (rather than an emotion). Neurobiologically, this state of person-directed motivation is based on the activity of (among other things) dopaminergic (reward) systems and therefore has a very strong influence on the behaviour of the person in love. The study discussed here, published in the Journal of Neurophysiology (2010), is a further step in this team's research into the phenomenon of love ('romantic love'), but analyses the activity of neuronal systems in the context of rejection in love ('rejection in love').
