Episode 47 of the Brain Science Podcast is a discussion of Principles of Brain Evolution
by Georg F. Striedter. My goal is to highlight the main ideas of this
complicated, and often controversial subject. Understanding the
principles of brain evolution is an important element in our
multidisciplinary attempt to understand how our brains make us who we
are.

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 exaggerate 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.

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.
I have posted my schedule of appearances for Dragon*Con 2008, which is being held in Atlanta, GA, August 28- September 1. Send me an email at docartemis at gmail.com if you would like to get together during the Con. Please mark your schedule for the LIVE Brain Science Podcast Sunday at 2:30 PM and my presentation “The New Brain Science” on Monday at 2:30 PM. Click here for a detailed list of my appearances.
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.

Episode 43 of the Brain Science Podcast is an interview with Robert A Burton, MD, author of On Being Certain: Believing You Are Right Even When You’re Not, which I discussed in Episode 42.
Dr. Burton tells us what inspired him to write this book and we explore
some of the implications of the fact that what he calls the “feeling of
knowing” comes from our unconscious, including the fact that it is not
as reliable as it feels.

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.

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.

Episode 38 of the Brain Science Podcast is an interview with Jeff Hawkins, author of On Intelligence.
Hawkins is well-known for founding Palm Computing and Handspring. He
invented the Grafitti handwriting recognition system and helped develop
the Palm Trio SmartPhone. Since he published his bestseller On Intelligence, he has devoted his work to his passion for neuroscience. His current company Numenta
is developing software that models the hierarchal structure of the
neocortex. In this interview we talk about the ideas in Hawkins book
and how he is applying them to develop a computer model of cortical
function. This is a follow-up to Episode 2, which first aired in December of 2006.

Episode 37 of the Brain Science Podcast is an interview with Dr. John Medina, author of Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School.
We talk about how exercise, sleep, and stress effect our brains with an
emphasis on practical advice for healthier brain function. We also look
at how research on memory, vision and the brain's attention system
suggests how we can improve our ability to learn and our ability to
share ideas with others.
Dr. Medina's focus is on considering real world examples of how our schools and work environments could be reformed to utilize the growing knowledge of neuroscience. But he also stresses the importance of compiling sufficient experimental data before embarking on new programs.
