Lobes and Robes

Neuroscience for Everyone! Advances in neuroscience have important implications for the development of policies designed to meet looming challenges in health care, aging, education, bioethics, child welfare, environmental and national security. Furthermore, addiction, violent crime, dementia, and obesity pose threats to our well-being that are unlikely to be addressed effectively without the translation of sound behavioral and neuroscience into effective public policy and law. Lobes and Robes, a new podcast developed by the Department of Neuroscience in cooperation with the School of Public Affairs and the Washington College of Law, brings scientists and policymakers together to address some of the most pressing problems of our time. Lobes and Robes is produced by the American University’s Center for Neuroscience and Behavior shares dispatches from the intersection of law, science, and public policy.

This episode features popular culture critic Dr. Despina Kakoudaki, author of the book Anatomy of a Robot: Literature, Cinema, and the Cultural Work of Artificial People. Dr. Kakoudaki, a professor at American University, discusses how fantasy and science fiction imagine artificial persons. She discusses how literary and cinematic art depict machines as having human-like, or even super-human, intelligence and behavioral capabilities. In our wide-ranging discussion, we consider the implications of these ideas about the machines that science and technology are developing. We discuss how concepts of machines’ human-like tendencies are affecting current culture, definitions of personhood, and ideas about human evolution. We close with a discussion of how knowledge about the operation of the human brain has contributed to the development of artificial intelligence, and how, in turn, the development of increasingly sophisticated models of artificial intelligence may contribute to knowledge about the human brain.

This episode features leading researcher on therapeutic uses of psychedelics, Dr. Matthew W. Johnson of the Sheppard Pratt Institute for Advanced Diagnostics and Therapeutics. Dr. Johnson summarizes the current research on the potential benefits of psychedelics for treatment of depression, addiction, and other conditions; the known risks and benefits of such treatments; and Dr. Johson’s important work on developing best practice guidance in relation to safety, risk assessment, and ethics in psychedelics research and treatment. We discuss recent developments in the U.S. Food and Drug Administration’s (FDA) consideration of a request for approval of MDMA for treatment of post-traumatic stress disorder, the special problems the FDA faces in assessing psychedelics for possible therapeutic uses, and the dangers that continued unregulated uses of psychedelics pose in the absence of FDA approval and regulation. We end by hearing from Dr. Johnson about his future research plans.

The “gut–brain axis" is a system by which the gastrointestinal tract communicates with the brain. In this episode, Dr. Scott Kanoski, Co-director of the Diabetes and Obesity Research Institute at the University of Southern California, shares his research and expertise about the gut-brain system. He discusses how diet, hormones, and the millions of bacteria that comprise our gut microbiota act on this system. As he explains in this wide-ranging discussion, recent findings from his lab and many others are revealing how these signals affect the brain in ways that have profound impacts on appetite, cognitive functioning, and impulse control.

This episode features Dr. Francis Shen, a leader in the emerging field of “neurolaw,” which seeks to bring the insights of neuroscience and law together in ways that can be mutually beneficial to both disciplines. Dr. Shen shares his insights into some of the areas in which neurolaw shows great promise, including law and mental health, aging brains, brain injury, lie detection, and more. We discuss the need to train lawyers and judges on how to assess neuroscience findings and the different ethical requirements lawyers and scientists operate under, and end with Dr. Shen’s thoughts about neurolaw’s future.

The effects of consuming non-nutritive sweeteners on weight control and health and well-being have been a source of continuing controversy. Dr. Sylvetsky, a professor and scientist at the Milken Institute School of Public Health at George Washington University in Washington DC, talks with us about her research on the consumption of artificially sweetened food and beverages by children and adults. She discusses recent guidance provided by the World Health Organization about the use of non…

Alzheimer’s Disease and similar late-life dementias pose serious threats to human health and well-being.  These cognitive disorders can be devastating not only for patients, but also for the family members and friends that care for them. Dr. Gayatri Devi, MD, a nationally recognized neurologist and author of the influential book, ”A Spectrum of Hope: An Optimistic and New Approach to Alzheimer’s Disease and Other Dementias,” shares with us her extensive knowledge about memory and cognitive dysfunction and her innovative treatment approaches.  Dr. Devi proposes that precision medicine will be the treatment modality of choice in the future and that, through it, we will be seeing significant improvements in the quality of life of patients with Alzheimer’s disease.

The desire to lose weight is pervasive in our society.  Some people want to lose a few pounds to look better while for many others weight loss can help to reduce serious threats to their health and well-being.  Historically, dieting as a means of losing excess pounds, and keeping lost weight off, has produced disappointing results for many people. However, there are surgical and, more recently, pharmacological interventions that can produce significant and sustained weight loss. But are such treatment safe as well as effective?  And how do they work? On this episode, Dr. Randy Seeley of the University of Michigan School of Medicine addresses questions about the effectiveness and safety of both bariatric surgery and the new GLP-1 agonist drugs  (e.g., Ozempic, Wegovy, Mountjaro) in producing and sustaining weight loss.

This episode builds from Dr. Khohkar’s interview in our last episode in which he outlines the many ways in which discrimination and hate-based behavior have been shown to have negative effects on the brain, both for those subject to such behavior and perpetrators, as well as bystanders and others. In this episode we talk with expert psychologist Dr. Linda McGhee, whose fields of specialization include the treatment of the psychological effects of racial trauma. Dr. McGhee discusses her background, her current areas of focus, and the approaches she uses, including liberation-based trauma treatment. She also offers suggestions about how academic disciplines and other institutions can engage in self-assessment to improve opportunities for access and success for traditionally excluded outsiders including racial minorities and others.

In this episode, with neuroscientist and anti-discrimination advocate Dr. Jibran Khokhar, we explore the effects on the brain of experience with race-based and other identity group-based discrimination including Islamophobia. Dr. Khokhar discusses findings from neuroscientific, psychological and epidemiological studies that reveal the adverse health effects of experiencing such discrimination, including increased risks for depression, anxiety, stress and suicide. He also discusses evidence indicating that heightened activity in the amygdala, a brain structure associated with fear and anxiety, is a significant consequence of being indirectly exposed to such discrimination via the media or other sources. Based on these findings, taking care to avoid implicit bias and to promote racial, religious and other forms of inclusion and equity in academic settings and other institutions, may provide a way to address these sources of harm.

This episode puts previous guest Dr. Tara White in dialogue with Professor James May of Delaware Law School, an expert on human rights law and dignity jurisprudence. Along with our cohosts, Dr. White and Prof. May explore the many points of overlap between dignity neuroscience and the principles of human rights law. They discuss issues including human agency, the right to be free from fear and want, and the emerging consilience between the principles of human rights law and what science shows about the resources the brain needs for healthy development. The discussion ventures into future potential directions for inquiry highlighted in exploring these subjects together.
