The Focus on Neuroscience Box "Romantic Love and the Brain

The Focus on Neuroscience box "Romantic Love and the Brain" describes a study in which love-struck young adults underwent an fMRI brain scan while they looked at a photo of their beloved or at a photo of a friend. The results of this study indicated:

A) that looking at a photo of their lover produced a marked reduction in brain activity, especially in the left hemisphere.
B) that, when viewing a photo of their lover, females showed significant right hemisphere brain activation, while males showed significant left hemisphere brain activation.
C) that, when the participants viewed a photo of their lover, it activated some of the same brain areas that are activated by euphoria-producing drugs, such as opiates and cocaine.
D) no significant differences, as both photos activated the same visual areas of the brain.
