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.

Michael Arbib on Mirror Neurons (BSP 39)

Episode 39 of the Brain Science Podcast is an interview with Dr. Michael Arbib from the University of Southern California. Dr. Arbib's work with functional brain imaging has established the presence of mirror neurons in the human brain. In our interview we focused on the role of mirror neurons in imitation and language. In particular I questioned Dr. Arbib about the Mirror System Hypothesis (MSH) of Language Evolution that he proposed in 1998 with Giacomo Rizzolatti. We also explored how this hypothesis diverges from the universal grammar proposed by Noam Chomsky. Dr. Arbib also shared his enthusiasm for future research and we talked about the special challenges caused by the interdisciplinary nature of modern neuroscience.

Could the eye have evolved? The answer is YES!

I have been meaning to recommend the excellent website Expelled Exposed, which documents all the lies and misleading statements in Ben's Stein's creationist "documentary," Exposed. A central claim is that professors who believe in intelligent design are being persecuted, a claim that is totally unfounded. Expelled Exposed was created by the National Center for Science Education. You can hear an excellent interview with Director Eugenie Scott on the April 9th episode of Science Talk, Scientific American's podcast. One of the claims that is popular with ID proponents is the idea that the eye is too complex to have been the product of evolution. Actually, as was pointed in David Bainbridge's excellent book, Beyond the Zonules of Zinn: A Fantastic Journey Through Your Brain, nothing could be further from the truth, because there is evidence that eyes have actually evolved a surprising number of times. (For more on Bainbridge's book listen to Episode 32 of the Brain Science Podcast.) To learn more about the evidence for the evolution of the eye check out this new video which NCSE has posted on YouTube: http://www.youtube.com/watch?v=fOtP7HEuDYA

Nancy Yanes Hoffman reviews "When Doctors Become Patients"

When Doctors Become Patients I have mentioned Nancy Yanes Hoffman's Writing Doctor's Blog several times in the past. She has graciously allowed me to quote from her recent review of WHEN DOCTORS BECOME PATIENTS by Robert Klitzman.
When Harcourt bought CHANGE OF HEART: The Bypass Experience, my book interviewing 1100 veterans of coronary bypass surgery, I was elated. Flush with my success, I tried to convince them to publish my next book interviewing 100 doctors who were veterans of coronary bypass surgery. “Nobody will be interested,” retorted the editor. But he was wrong. Robert Klitzman’s important new book, WHEN DOCTORS BECOME PATIENTS, proved just how wrong one editor can be. Klitzman interviewed 70 physicians, male and female, young and old—from 25 to 87, all victimized by a variety of chronic and acute diseases including lymphoma, breast cancer, skin cancer, Huntington’s disease, heart attacks, depression, bipolar distress, and an overly high incidence of HIV. Whatever their illnesses were, disease was isolating. Even though their different illnesses mandated a variety of diagnoses, treatment, responses, and coping mechanisms, many sick doctors felt left on their doorsteps by calloused and unsympathetic colleagues. Since 34 percent of doctors in Klitzman’s study were HIV positive or suffered from frank AIDs, most opted for secrecy. But the four women physicians killed by metastatic cancer within a year after Klitzman finished his book also faced “peripheralization and discrimination.” One physician reporting that her colleagues “treated me as if I were dead.” Even if these doctor-patients wanted to talk to their physicians, communicating with physicians was a tough ball game. Here, the doctor who is sick confronts the same barriers as the non-doctor who wants to communicate with his or her physician. (Read the rest.)
Actually the obstacles between physician-patients and their physicians are more difficult than one might imagine. In my own personal experience I have found that it is actually better when my physician forgets I am a doctor (which seems to be surprisingly easy for male docs taking care of female collegues!).

Art Glenberg discusses Embodied Cognition (BSP 36)

Art Glenberg, PhD Episode 36 of the Brain Science Podcast is an interview with Arthur Glenberg, PhD about embodied cognition. Dr. Glenberg recently moved to Arizona State University after over 30 years at the University of Wisconsin's Laboratory of Embodied Cognition. His research focuses on the relationship between embodiment and language. In this interview we explore the experimental evidence for a theory of language that embraces the concept that our language abilities are actually rooted in our perceptual and motor abilities. Dr. Glenberg also explains how his work has practical implications in helping children learn how to read. Since Dr. Glenberg has had a long career as a working research scientist, this interview also provided an opportunity to explore how scientific hypotheses are formed and how experiments are designed to test these hypothesis. I think this interview will give you a fascinating look into the real world of cognitive psychology.

Mirror Neurons (BSP 35)

Mirrors in the Brain Brain Science Podcast #35 is a discussion of Mirrors in the brain: How our minds share actions, emotions, and experience by Giacomo Rizzolatti and Corrado Sinigaglia. Mirror neurons were discovered in Rizzolatti's lab in Parma Italy in the early 1990's and his book is a detailed to discussion of the experimental evidence in both monkeys and humans. Direct single neuron recordings have been made in monkeys. The evidence in humans is indirect since it is based on mainly on neuroimaging studies like PET scans and fMRI scans. Even so mirror neurons appear to be essential to our ability to understand both the actions and emotions of others. Listen Now. In this episode we also explore the evidence that there are other neurons in the motor areas of the brain that have sensory properties and that the areas of the brain traditionally thought to be devoted to sensory functions also contain neurons with motor properties. Another fascinating discovery is the fact that there are neurons that respond not only to somatosensory inputs (such as being touched) but also to visual or auditory inputs from objects within our peri-personal space. For background on these body maps I recommend listening to Episode 21 and Episode 23. If you are new to the Brain Science Podcast you may want to listen to those episodes first because this week's episode is a little more technical than most. I will be exploring the importance of these discoveries in future episodes.

Dan Rather Presents Neuroplasticity

Today HDNet™ is reshowing an episode of Dan Rather Reports called "Mind Science." It is an excellent review of neuroplasticity. It includes interviews with several leading scientists in the field. I especially enjoyed seeing Nobel Laureate Eric Kandel talk about his work with memory. (I talked about Kandel's work on the Brain Science Podcast in Episode 3 and Episode 12.) "Mind Science" also features the Dalai Llama and scientist Richard Davidson talking about the evidence that meditation can change the brain. Rather interviews Sharon Begely about her book Train Your Mind, Change Your Brain: How a New Science Reveals Our Extraordinary Potential to Transform Ourselves (which I discussed in detail in Episode 10 of the Brain Science Podcast). Other scientists featured in the episode include Michael Merzenich on improving brain function as we age and Dr. Edward Taub on his revolutionary approach to stroke rehabilitation. (My show notes for Episode 10 include links for all the scientists interviewed by Rather.) It was particulary gratifying to see Dr. Kandel endorse Ed Taub's Constraint-Induced Movement Therapy. Dr. Taub was interviewed in Episode 28 of the Brain Science Podcast. If you don't get HDNet™ you can watch Dan Rather Reports on-line, via podcast or on Facebook.

The Philosophy of Buffy the Vampire Slayer?

alan_saunders.jpg Alan Saunders of The Philosopher's Zone One of my favorite podcasts is an Australian Radio show called The Philosopher's Zone, but I have to admit that I was surprised to discover that host Alan Saunders shares my passion for the work of Joss Whedon, especially Buffy the Vampire Slayer. The March 29 episode is a discussion of the philosophical aspects of the BuffyVerse with James B. South who edited Buffy the Vampire Slayer and Philosophy: Fear and Trembling in Sunnydale (2003). The episode is called "Buffy the Concept Slayer," which is kind of a lame title, but it is still something Buffy fans will enjoy. However, it is not an episode someone new to the show will find very enlightening.

The Myth of Free Will: Revised and expanded

mythoffreewill-2nd.jpg Back in Episode 12 I reviewed the first edition of The Myth of Free Will: Revised & Expanded Edition (2008) by Cris Evatt. I am proud to announce that I have a short chapter in the revised edition "My Brain Made Me Do It." This essay is a reflection on the implications of the recent findings of neuroscience that indicate that a large amount of our brain's decision-making occurs outside our conscious awareness. Even so I argue that the concept of personal responsibility should not be abandoned because our frontal lobes do have the ability to overrule many reflex decisions. I also consider the implications of neuroplasticity. You can find this book in the Books and Ideas aStore within Amazon.com.
