Scientists studies on love activities in Human brain

Dr. Lucy Brown, a professor in the department of neurology and neuroscience at the Albert Einstein College of Medicine in New York, and her colleagues believe that the caudate and the ventral tegmental areas in our brain are responsible for most of the emotion we have about love. They found out that when we are in love, ventral tegmental floods the caudate with dopamine that makes us high, just as if we have taken cocaine.

Few interesting points learned from the team,
That brain in love and brain in lust does not look alike.
That falling in love makes someone becomes extra sexy.
That men’s brain are more active in the area of visual stimuli.
That women remember things about men is her physical ability to choose a good husband and father, as when they are in love, not in lust.
When we did crazy thing for love, we are high on dopamine.
