Nerve Growth Factor - Cultural Significance

Cultural Significance

In 2005, Enzo Emanuele and coworkers at University of Pavia found that nerve growth factor (NGF) has high levels when people first fall in love, but these levels return to as they were after one year. To be specific, four neurotrophin levels, i.e., NGF, BDNF, NT-3, and NT-4, of 58 subjects who had recently fallen in love were compared with levels in a control group who were either single or already engaged in a long-term relationship. The results showed that NGF levels were significantly higher in the subjects in love than as compared to either of the control groups. Nerve growth factor may contribute to increased longevity and mental capacity. Centenarian Rita Levi-Montalcini has been taking a daily solution in the form of eye drops, and has stated that her brain is more active now than it was four decades ago.

Famous quotes containing the words cultural and/or significance:

    Somehow we have been taught to believe that the experiences of girls and women are not important in the study and understanding of human behavior. If we know men, then we know all of humankind. These prevalent cultural attitudes totally deny the uniqueness of the female experience, limiting the development of girls and women and depriving a needy world of the gifts, talents, and resources our daughters have to offer.
    Jeanne Elium (20th century)

    I am not afraid that I shall exaggerate the value and significance of life, but that I shall not be up to the occasion which it is.
    Henry David Thoreau (1817–1862)
