Recorded LIVE at Dragon*Con 2008 (BSP 46)

Dragon*Con 2008 Dragon*Con 2008 Brain Science Podcast #46 is a discussion of brain imaging with Dr. Shella Keilholz and Dr. Jason Schneiderman. The focus of our discussion is functional magnetic resonance imaging (fMRI), which is revolutionizing neuroscience. We talked about both the strengths and weaknesses of this technique. Both of my guests agree that mainstream coverage of this technique tends to exagerate what we can actually tell from this kind of brain scan. An important principle is that the scan of any single individual can vary greatly from day-to-day, which means that valid conclusions require data from a large number of people.

Attention Deficit Disorder with Dr. John Ratey (BSP 45)

Have you ever wondered why a child with ADD can play videos games for hours but can’t concentrate on his homework for a few minutes? This is one of the paradoxes of attention-deficit disorder that  John J Ratey, MD, co-author of Driven To Distraction : Recognizing and Coping with Attention Deficit Disorder from Childhood Through Adulthood, explains in Episode 45 of the Brain Science Podcast. During this interview Dr. Ratey discusses the latest findings about the biological basis of what he calls “attention variability disorder.” He also offers practical advice for patients and parents dealing with ADD/ADHD. One very important, and somewhat surprising, fact that he shares is that patients who are treated with medications during adolescence have a significantly lower risk of developing problems with addiction and drug abuse later on compared to those who are not treated. Also, successful “ADDers” like Michael Phelps show that “having a mission” makes a huge difference. Dr. Ratey’s most recent book is Spark: The Revolutionary New Science of Exercise and the Brain, which he discussed with me (Dr. Campbell) in Episode 33.

Daniel Siegel, MD on Meditation and the Brain (BSP 44)

Daniel Siegel, MD In Episode 44 of the Brain Science Podcast I talk with Daniel Siegel, MD about meditation and the brain. Dr. Siegel is the author of several books including The Mindful Brain: Reflection and Attunement in the Cultivation of Well-Being. In this interview we review the scientific evidence about how mindfulness meditation changes the brain, both in terms of short term activity and in terms of long-term structural changes. The evidence is convincing that a regular mindfulness practice can be an important element of brain health.

Review: "On Being Certain" (BSP 42)

Episode 42 of the Brain Science Podcast is a discussion of On Being Certain: Believing You Are Right Even When You're Not by Robert Burton, MD. This part 1 of a two part discussion of the unconscious origins of what Dr. Burton calls "the feeling of knowing." In Episode 43 I will interview Dr. Burton. Today's episode provides an overview of Dr. Burton's key ideas. In past episodes I have discussed the role of unconscious decision-making. On Being Certain: Believing You Are Right Even When You're Not by Robert Burton, MD takes this topic to a new level. First, Dr. Burton discusses the evidence that the "feeling of knowing" arises from parts of our brain that we can neither access or control. Then he discusses the implications of this finding, including the fact that it challenges long-held assumptions about the possibility of purely rational thought.

Dr. Eugenie Scott on Teaching Evolution (B&I 21)

Eugenie Scott, the Executive Director of the National Center for Science Education, was interviewed in Episode 21 of Books and Ideas. The focus of our conversation was the importance of teaching evolution in the public schools. Dr. Scott and the NCSE have worked for over 20 years to promote the teaching of evolution because it is an essential component of a modern education in the life sciences. Unfortunately, nearly 150 years after Darwin's On the Origin of Species (1859) many Americans still reject this fundamental idea and much of Scott's work is focused on trying to keep creationism and so-called Intelligent Design out of school curriculum. Recently the NCSE launched a very valuable site called Expelled Exposed, which focuses on exposing the many inaccuracies presented in Ben Stein's recent pro-intelligent design "documentary" Expelled. One of the things that has come out in numerous interviews is that the producers of the film mislead all the pro-evolution guests that appear in the film. We discuss this briefly near the end of the interview, but it was not the focus of our discussion. (see below for more links regarding Expelled) Since Dr. Scott has been interviewed about Expelled and Expelled Exposed on several other podcasts, I wanted to focus our interview more on the importance of accurate science education. Also, we discussed the fact that despite the claims of right-wing fundamentalists there are many Christians and people of other faiths who accept the theory of evolution as scientifically valid. Accepting evolution does not mean one is choosing atheism. I think this is a very important distinction because while atheists are outspoken in their support of evolution they represent a small minority. I was encouraged to learn from Dr. Scott that the NCSE is working closely with religious leaders and scientists of faith to try to educate their members. Since Books and Ideas reaches an international audience I thought that it was important that we discuss the origins of the evolution versus creationism controversy, which is unique to the United States. Scott does an excellent job of explaining how our unique religious heritage along with our locally controlled school systems combine to create a situation that most of the world find's rather mystifying. Her book Evolution vs. Creationism: An Introduction also provides an excellent overview of the subject from both an historical and scientific prospective. Finally, we talk about the importance of evolution as a basic idea in modern biology. While we didn't dwell on this, I think we are both concerned about the implications for the future if a majority of young Americans are reaching college without a solid foundation in the principles of evolution. We also talked about why intelligent design fails to meet the basic definition of a scientific theory since it provides no testable hypotheses. Dr. Scott also provides a excellent review of the basic writings for those who want to learn more.

Dr. Steven Novella from "The Skeptics Guide to the Universe" (B&I 16)

steve_bw.jpg Episode 16 of Books and Ideas is a conversation with Dr. Steven Novella from the popular podcast The Skeptics Guide to the Universe. This interview is a response to numerous requests from fans of the Brain Science Podcast, but I put it in the Books and Ideas feed so that Dr. Novella could share some of his personal experiences both as a physician and as a podcaster. Listen to Dr. Novella's interview Subscribe to this podcast Subscribe via iTunes™ Subscribe by email Subscribe to Books and Ideas Blog Leave comments at the Discussion Forum Show Notes: Dr. Novella talked a little bit about why he became a physician and about choosing neurology as his specialty. We talked about the role of imaging and how recent advances in neuroscience are influencing patient care. We also talked about the importance of helping patients get accurate information, both from the internet and from their physicians, and how the pressure for physicians to see large numbers of patients hinders good communication. Dr. Novella is committed to evidence-based medicine and we talked about the role of skepticism in evaluating medical claims, both from mainstream and alternative sources. Dr. Novella also talked briefly about his podcast and his blogs, including a new blog specifically devoted to promoting evidence-based medicine. In the last section of this episode I looked back on the first 15 episodes of Books and Ideas. I particularly want to thank Matthew Cobb for being my first guest back in episode 7.

Review: "The Trouble with Physics" (B&I 2)

troublewithphysics-small.jpg Show Notes This episode turned out longer than I planned. After I recorded a piece about Lee Smolin’s book The Trouble with Physics: The Rise of String Theory, the fall of a science, and What Comes Next, I decided to wait until the next episode to discuss my Audible.com top 10 for 2006. I think Smolin’s book makes an important contribution on several levels. First, it is an excellent review of contemporary physics and puts string theory into context. It is also a candid look at the trends in contemporary science that are stifling original thinking and creativity. It is a passionate defense of the traditional scientific method (making predictions and testing them with experiments). If physics, which has always been thought of the purest science could lose site of its principles, we are reminded that science is a human endeavor, prone to human error and human desires.
