When in comes to the debate of “nature vs nurture“…
And the STRUCTURE of the brain?
“Nurture” wins out.
[via ScienceDaily]Specific Changes in Brain Structure After Different Forms of Child Abuse
June 1, 2013 — Different forms of childhood abuse increase the risk for mental illness as well as sexual dysfunction in adulthood, but little has been known about how that happens. An international team of researchers, including the Miller School’s Charles B. Nemeroff, M.D., Ph.D., Leonard M. Miller Professor and Chair of Psychiatry and Behavioral Sciences, has discovered a neural basis for this association. The study, published in the June 1 issue of the American Journal of Psychiatry, shows that sexually abused and emotionally mistreated children exhibit specific and differential changes in the architecture of their brain that reflect the nature of the mistreatment.
Researchers have known that victims of childhood abuse often suffer from psychiatric disorders later in life, including sexual dysfunction following sexual abuse. The underlying mechanisms mediating this association have been poorly understood. Nemeroff and a group of scientists led by Christine Heim, Ph.D., Director of the Institute of Medical Psychology at Charité University of Medicine Berlin, and Jens Pruessner, Ph.D., Director of the McGill Center for Studies in Aging at McGill University in Montreal, hypothesized that cortical changes during segments of mistreatment played a role. To study these potential changes, the researchers used magnetic resonance imaging (MRI) to examine the brains of 51 adult women who were exposed to various forms of childhood abuse.
The results showed a correlation between specific forms of maltreatment and thinning of the cortex in precisely the regions of the brain that are involved in the perception or processing of the type of abuse. Specifically, the somatosensory cortex in the area in which the female genitals are represented was significantly thinner in women who were victims of sexual abuse in their childhood. Similarly, victims of emotional mistreatment were found to have a reduction of the thickness of the cerebral cortex in specific areas associated with self-awareness, self-evaluation and emotional regulation.
“This is one of the first studies documenting long-term alterations in specific brain areas as a consequence of child abuse and neglect,” said Nemeroff, who is also Director of the Center on Aging. “The finding that specific types of early life trauma have discrete, long lasting effects on the brain that underlie symptoms in adults is an important step in developing novel therapies to intervene to reduce the often lifelong psychiatric/psychological burden of such trauma.”
But just because one’s brain has re-designed itself to form a protective mechanism against all of the negative things one has endured…
Doesn’t mean one’s intrinsic, balanced inner NATURE has no chance to prevail!
It’s all about perspective:
“Nietzsche was the one who did the job for me. At a certain moment in his life, the idea came to him of what he called ‘the love of your fate.’ Whatever your fate is, whatever the hell happens, you say, ‘This is what I need.’ It may look like a wreck, but go at it as though it were an opportunity, a challenge. If you bring love to that moment—not discouragement—you will find the strength is there. Any disaster that you can survive is an improvement in your character, your stature, and your life. What a privilege! This is when the spontaneity of your own nature will have a chance to flow.
“Then, when looking back at your life, you will see that the moments which seemed to be great failures followed by wreckage were the incidents that shaped the life you have now. You’ll see that this is really true. Nothing can happen to you that is not positive. Even though it looks and feels at the moment like a negative crisis, it is not. The crisis throws you back, and when you are required to exhibit strength, it comes.”

Something positive can come out of EVERY negative.
