The love between couples or romantic love is a very deep feeling and a powerful motivational impulse that moves our lives. Not so very long, love was considered territory of the poets or philosophers, but since 10 years ago Neuroscience has allowed us to explore the depths of the brain for observing how this one changes when we fall in love at first sight, we continue with our couple for years or we are abandoned or we look for another partner. During the course the psychobiological foundations of brain and hormonal changes that occur when we fall in love and its evolutionary aspects, the psychobiology of sex, will be explained. Exclusive course for Unimajors students.
