Keynote Address Stress, Sex and the Hippocampus
You are here: Home > research > 12th Research Day > Keynote Speaker ABSTRACT: KEYNOTE ADDRESS STRESS, SEX AND THE HIPPOCAMPUS: FROM SERENDIPITY TO CLINICAL RELEVANCE Bruce S. McEwen, PhD Lab Neuroendocrinology, Rockefeller University, New York, NY The hippocampal formation, which expresses high levels of adrenal steroid receptors, is a plastic brain structure that is important for certain types of learning and memory. It is also vulnerable to insults such as stroke, seizures and head trauma. The hippocampus is also sensitive and vulnerable to the effects of stress and stress hormones and it is responsive to the actions of sex hormones as well, both during development and adult life. Stress and sex hormones regulate 3 types of structural plasticity in the adult hippocampus: synaptogenesis, reorganization of dendrites, and neurogenesis in the dendrite gyrus. Developmentally-programmed sex differences are also seen in the hippocampus. Suppression of dentate gyrus neurogenesis and atrophy of dendrites of hippocampal pyramidal neurons are produced by chronic psychosocial stress, involving the actions of adrenal steroids acting in concert with excitatory amino acid neurotransmitters. As far as we can tell, these changes are reversible as long as stress is terminated after a number of weeks. However, there are also reports that much longer durations of psychosocial stress leads to permanent loss of hippocampal pyramidal neurons. In the human hippocampus, MRI studies along with neuropsychological testing have revealed memory impairment and atrophy of the whole human hippocampus in some individuals as they age. This is reminiscent of individual differences in aging in rodents, which appear to reflect life-long patterns of stress hormone reactivity that are developmentally programmed, although a developmental influence upon human individual differences is only a matter of speculation. -

Robert Sapolsky “They” Are Individuals: the Power of Perspective on Peace-Making
Robert Sapolsky “They” are Individuals: The Power of Perspective on Peace-making By Angela Lee & Jinxia Niu Summary: The problem: human tendencies to perceive ingroups/outgroups Insights on how to neutralize/decrease this tendency The importance of thinking about people as individuals Power of "sacred values" and symbolic acts Empathy and individuation Insights from reconciliation in animals Change behavior, then attitudes to increase cooperation, decrease group-based hate Conclusion: We have the ability to change our divisions of groups Robert Sapolsky is an American biologist, neurologist, author, and professor at Stanford University. The recipient of numerous awards for his work, including the MacArthur Fellowship, the Alfred P. Sloan Fellowship, and the John P. McGovern Award for Behavioral Science, he is best known for his research on primate behavior, the impact of stress on neuroendocrinology, and behavioral biology. His most recent book, Behave: The Biology of Humans at Our Best and Worst, combines biological and psychological insights to discuss human behavior, social structures, and implications for justice in the absence of free will. An advocate for multidisciplinary efforts in research, Sapolsky drew on his own experiences and his extensive background in the social and natural sciences to share evidence that offers hope for the human potential to cooperate and overcome conflict. The key, he believes, lies in overcoming innate, enduring mindsets portraying disputes as between “us” and “them.” Fostering empathy and deliberate shifts in perspective can help us remember that “they” are more than just “the enemy.” They are individuals - with their own motivations, feelings, and families. He also encourages recognition of the power of symbols and sacred values. -
Ask the Experts Forum #5: Your Position in Society
ASK THE EXPERTS FORUM #5: YOUR POSITION IN SOCIETY Nancy Adler, Bruce McEwen, and Peter Schnall address chronic stress, the wealth-health gradient, unemployment, and why women live longer than men. QUESTION #1: If wealth determines health, then why do women – who are routinely paid less than men – live longer? NANCY ADLER: First, we should note that women live longer than men but have higher rates of a number of chronic diseases. So if you actually look at what’s called “quality-adjusted life expectancy,” the gap isn’t as great. But why do women live longer than men? I think the short answer is there appear to be some biological advantages that women have, particularly estrogen, which protects women against cardiovascular disease, the biggest single cause of death in the United States. So pre-menopausally, women are protected and it shifts the mortality from heart disease a number of years. We also see a female biological advantage even at birth. Female fetuses survive at greater rates than do male fetuses, particularly if the pregnant woman is stressed, suggesting that female fetuses may have a little bit of a biological advantage. But it’s also important to think about some related issues. Wealth isn’t the only social determinant of health. If you stuff your pockets with money, it doesn’t make you healthier. It’s what money gets you, along with other social resources, that matters. And women have other resources. Education is an important determinant of health, and women are graduating from high school and from colleges at somewhat greater rates than men. -

Law and the Brain Tulane University Law School 4LAW 4210 Administrative Memo & Syllabus Professor Francis X. Shen Fall 2011 Location: Room 302 Wednesdays, 10:00 am – 12:00 pm What are adolescents, psychopaths, and white-collar fraud artists thinking? Why does emotional trauma for victims of abuse last so long? Why is eye-witness memory so poor? How can you get into the heads of the judge and jury? Questions like these are asked all the time by lawyers, and increasingly brain science is providing legally useful answers. U.S. courts, including the U.S. Supreme Court, are already integrating neuroscience research into opinions. This Law and the Brain seminar will introduce the exciting new field of “neurolaw” by covering issues such as the neuroscience of criminal culpability, brain-based lie detection, memory enhancement, emotions, decision making, and much more. Along the way we’ll discuss how the legal system can and should respond to new insights on topics such as adolescent brain development, addiction, psychopathy, Alzheimer’s, the effects of combat on soldiers’ brains, and concussions from sports injuries. (Note that all scientific material in the seminar will be presented in an accessible manner, so no previous science background is required.) Instructor: Dr. Francis X.

It's a Golden
It’s A Golden Age Miracles happen, and emotional plasticity may be one of them. A few years ago, I met with a warm, fatherly psychiatrist to explain the science and methods of EBT. During our conversation, there came a moment when words failed me. I suggested that he try one of the tools, and he demurred, so I volunteered to demonstrate the technique. I had not been aware of how stressed I was at the time – that I feared that I would never get this method out and would go to my grave with the tools still inside me. However, in the warm womb of his comfy office, I launched into using a tool. I fired up anger that sported a few expletives, made a brief pass through sadness with tears sparkling in my eyes, next touched on fear, and then on guilt. At that point, the bottom of my reptilian brain opened up. I had unlocked a previously unconscious, completely unreasonable expectation that had taken up residence in my brain. Perfect! Moments later, I had switched that expectation to a reasonable one of my choosing, and a burst of dopamine, oxytocin, and endorphins came over me. I was in joy! All of this had taken less than four minutes. He sat quietly. I had no idea what he would say. Then he gazed straight into my eyes and said, “Nothing in my 40 years of psychiatry has prepared me to explain what I just observed.” Through his eyes, my use of the tools must have seemed strange in two ways. -

E. Seeman University of California, Los Angeles Los Angeles, C A [email protected] A BST R A C T Stress is possibly the hallmark characteristic of the current conflicts confronting the United States. Extended and repeated deployments require the ability on the part of war-fighters to effectively process stress in ways never before routinely encountered. Stress is well defined as a series of psychological and physiological processes that occur in response to a stressor, or the perception of stress. The physiological response to stress follows an identified path, a robust neuroendocrine response leads to responses in the cardiovascular, metabolic, renal, inflammatory and LPPXQHV\VWHPV$IWHUDVWUHVVUHVSRQVHWKHERG\¶VQDWXUDOWHQGHQF\LVWRUHWXUQWRDVWHDG\VWDWHDSURFHVVFDOOHG allostasis. If the body is not effective in returning to homeostasis, or if the environment is such that stress is repeated, markers of dysfunction may be apparent in the physiological systems that respond to stress. A method of measuring multiple biomarkers of stress responsive systems and determining who shows consistent evidence of dysfunction was developed by Bruce McEwen and labeled allostatic load (AL). AL is most frequently measured by developing a level of risk for each biomarker and obtaining an AL score for the number of biomarkers the criterion for risk is met.
