Daniela and Rosangel,

Your blog summary was clear and accurate. I have looked at it carefully and made some changes that improve the sentence structure. You should check and note the differences.

In the University of Pavia, Italian scientist studied about a chemical in the brain. The name of the chemical is Nerve Growth Factor (NGF). They said when the people fall in love, they are happy and feel wonderful. . NGF and adrenalin increase when people fall in love, but their romantic feeling disappears in one year.

 Dr. Enzo Emnanuele explains the results through research with 58 volunteers. He compared  two groups, the first  single and the second  in steady relationships. He said the levels of NGF elevated among people in love. Also, he observed that NGF caused butterflies in stomachs and sweaty palms.
