Scientists have found that growth hormone, that promotes body growth, is produced in the brain according to an article published in the National Academy of Sciences. The researchers have been able to trace the origin of the growth hormone which is within the section of the brain in charge of memory and emotion - called the hippocampus.
The scientists have also zeroed in on the fact that more growth hormones are produced in females than in males, and more so during adulthood. Estrogen presence also triggered the production of growth hormones. The scientists also doubt the effect of growth hormones on reasoning and mood which may be altered by the differences in the amount of growth hormone in the brain.
Co-author Ken S. Kosik, co-director of the Neuroscience Research Center at the University of California, Santa Barbara said,"Growth hormone has been associated with growth of muscles and bones, and the production of it was believed to lie mainly in the pituitary gland.No one had thought too much about what growth hormone might be doing in the brain. Hormones in the brain may not be obvious compared to what they are doing in the rest of the body." Tracey J. Shors, co-author and a professor of psychology at the Center for Collaborative Neuroscience at Rutgers: the State University of New Jersey opined,"Males and females look different, we act different, so of course our brains are different. There are remarkable differences. People used to think of females as a male with hormones. That's just not the case.Sex hormones, like estrogen, have a tremendous effect on the growth and architecture of the brain. Several studies in our lab and in others have shown that males learn differently than females. It is possible that sex differences in these hormones are somehow involved."
