By Carlie Hoffman It is often said that we are products of our environment: who we are is shaped by the things, people, and situations with which we surround ourselves. However, whatever we may like to think, we are not in control of every facet of our environment. In fact, we are unknowingly and involuntarily exposed to dozens of man-made environmental chemicals, called toxicants , each day that can negatively alter our bodies and even our very brain matter. In essence, we are becoming literal products of our environment. Synthetic chemicals and toxicants are ubiquitous within our surroundings. While some toxicants come from obvious sources, like cigarette smoke and car exhaust, other sources of exposure are more subtle. For instance, electrical equipment (like computers and cell phones), beauty products (like makeup and shampoo), mattresses, and furniture all contain flame retardants , chemicals used to reduce flammability [3, 13]. Bisphenol A ( BPA ) and phthalates , c

His research focuses on understanding the etiology and neuropathology underlying severe mental illness. Elaine Walker is a Professor of Psychology and Neuroscience in the Department of Psychology at Emory University and is the Director of the Development and Mental Health Research Program, which is supported by the National Institute of Mental Health. Her research is focused on child and adolescent development and the brain changes that are associated with adolescence. She is also a member of the AJOB Neuroscience editorial board. Arthur Ryan, M.A. Over the past several decades, there has been a significant effort to minimize bias against individuals based on ethnicity and other demographic factors through the creation of seemingly impartial and objective criteria across a host of domains. For example, when the United States Federal Sentencing Guidelines wer

Discussing suicide can be difficult in clinical, public, and academic settings because many people have strong intuitions about which, when, and whether voluntary death is appropriate. However, discussions about suicide are largely abs

He is the author of 7 books, including Neuroethics (2007) and Consciousness and Moral Responsibility (2014), and edits the journal Neuroethics . He is also a member of the AJOB Neuroscience board. A recent study by Rachel Yehuda et al. in Biological Psychiatry provided further evidence for the genetic transmission of acquired characteristics, by showing that Holocaust survivors passed certain acquired genetic markers to their children. The idea that acquired characteristics can be genetically transmitted is (roughly) equivalent to the doctrine of Lamarckism , and was long considered a heresy in biology. [Editor's note: see also Ryan Purcell's 2014  post for this blog on the relationship between Lamarckism and epigenetics .] According to the Darwinian orthodoxy, traits change because randomly occurring mutations confer a relative fitnes

by Paul J. Ford, PhD Dr. Ford is Director of the NeuroEthics Program at the Cleveland Clinic. He is an active clinical ethicist, and teaches ethics to medical students, residents, and fellows. His publications have appeared in Science, The Hastings Center Report, Neurology, Neuromodulation, and Journal of Medical Ethics. He is also a board member for AJOB Neuroscience . This spring (June 3-4, 2015) the National Institutes of Health (NIH) as part of the BRAIN Initiative convened an eclectic group of individuals in hopes of encouraging more investigator initiated studies of currently approved neuromodulation and neuro recording devices for new indications (agenda, session videos, and program goals available here ). The participants, both on the program and in the audience, specifically included industry, researchers, universities, and governmental agencies. I was delighted to participate in the workshop and was impressed by the number of sincerely interested parties across the spect
