Ethical Implications of fMRI In Utero

When my neuroethics mentor approached me with a publication from Trends in Cognitive Science called “Functional Connectivity of the Human Brain in Utero” (1) in hand, I was immediately delighted by the idea of performing an ethical analysis on the use of functional Magnetic Resonance Imaging (fMRI) on fetuses in utero. As of right now, I’m still conducting this ethical analysis.  Using fMRI to look at human brains as they develop in utero is groundbreaking for a couple reasons. For one, there is a vast difference between the fMRI method currently used to investigate developing brains and previous methods that were used to examine fetal brain development. Research on developing brains had utilized preterm neonates, or babies born prematurely. While these data are valuable, there are issues with validity associated with this method: early exposure to an abnormal environment (e.g. being in the intensive care unit, where many pre...

The Brain In Context

By Sarah W. Denton Sarah W. Denton is a research assistant with the Science and Technology Innovation Program at the Wilson Center. Denton is also a research assistant with the Institute for Philosophy and Public Policy at George Mason University. Her research primarily focuses on ethical and governance implications for emerging technologies such as artificial intelligence, neurotechnology, gene-editing technology, and pharmaceuticals.  Tim Brown , University of Washington PhD student and research assistant with the Center for Sensorimotor Neural Engineering’s (CSNE) Neuroethics Thrust , introduced the session titled, “The Brain in Context,” at the International Neuroethics Society’s 2017 Annual Meeting moderated by Husseini Manji , Janssen Global Therapeutic Neuroscience Area Head. This session provided a multidisciplinary view of the challenges we face today in understanding the context of lived experiences and how our brains impact our environments. Getting at the h...

Overexposed: The role of environmental toxicants on your brain

Image
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...
