You will learn later in this unit that fMRI is based on the principle of measuring blood ow in specic parts of the brain. The assumption is that the more blood ow there is in a brain region, the more active the region is at this particular moment. So what was observed in Fisher, Aron and Brown’s (2005) study is that when you are looking at a picture of a person you love, there is more blood ow in the regions of your brain that are known to produce dopamine.

From this the researchers inferred the role of dopamine in romantic love. To what extent do you think it is a substantiated conclusion? Or is it far-fetched?
