Both involve the messenger chemical dopamine, which stimulates the brain's "reward centre". It is partly because of dopamine that we want to return to a source of pleasure, such as good food or sex.
Dopamine also acts to keep a &to=http://english.pravda.ru/world/2002/01/19/25861.html' target=_blank>drug addict hooked on cocaine or heroin. And, new research suggests, it helps one person to fall head over heels for another.
