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.

Rachel Herz talks about Smell (BSP 34)

/
rachelherz.jpgRachel Herz Episode 34 of the Brain Science Podcast is an interview with Rachel Herz author of The Scent of Desire: Discovering Our Enigmatic Sense of Smell (2007). Dr. Herz teaches at Brown University and she is a leading authority on the psychology of smell. We talk about the how smell works, its role in emotion and memory, why it is so vulnerable, and why smell is much more important than most of us realize. We also consider some of the questions that remain unanswered. Listen to the Rachel Herz interview now. (Right click to download.)

Brain Rhythms with György Buzsáki (BSP 31)

/
rhythmsofthebrain.jpg György Buzsáki, author of Rhythms of the Brain (OUP 2006) is a Professor of Neuroscience at Rutgers University. His book is a comprehensive review of the current state of research in the field of brain oscillations. It includes the role of these oscillations in sleep and memory. In episode 31 of the Brain Science Podcast Dr. Buzáki explains why the rhythms of the brain are important and reflects on why this field has been neglected by some neuroscientists. I think he makes a convincing case for the position that these rhythms are an essential component of brain function. Listen to Dr. György Buzsáki's interview about Brain Rhythms Transcript of Episode 31 SHOW NOTES: Partial List of Scientists Mentioned:
  • Stephen Strogatz: known for his discovery of "small world" architecture
    • His 2003 bestseller Sync: The emerging science of spontaneous order is aimed at a general audience
  • Nancy Kopell: mathematician
    • Buzsaki recommends her review of the analytical approaches to neuronal oscillators: We got Rhythm: Dynamical Systems of the Nervous System. N Am Math Soc 47: 6-16 (2000).
  • Zoltán Néda (Bebes-Bolyai University Romania): the spontaneous synchronization of hand clapping
  • Hermann Haken: German laser physicist who studies bidirectional causation
    • The Science of Structure: Synergetics (1984)
  • John O'Keefe (University College, London): along with Lynn Nadel he discovered how the hippocampus forms a cognitive map of the world
  • David McCormick (Yale University): showed that neurons from the thalamus of a ferret can oscillate spontaneously
    • He has also studied the oscillations of place cells in the hippocampus
  • David Hubel and Thorston Wiesal: along with Vernon Montcastle they pioneered the use of single neuron recordings in the neocortex of casts and monkeys
    • Montcastle, VB (1997) "The Columnar Organization of the Neocortex." Brain 102:01-722.
  • Claude Shannon: founder of Information Theory
  • Jan Born (University of Lübeck, Germany): experiments with how sleep improves both memory and problem solving
Topics and questions:
  • Basics of oscillations and synchrony
  • What functions are accomplished by brain rhythms?
  • The role of hippocampal ripples in memory
  • What happens to our brain rhythms while we sleep
  • The importance of synchrony in saving energy in the brain
This episode will appeal to listeners with a background in math or engineering, but Dr. Buzsáki provides numerous everyday examples that make the material accessible to everyone.

Natasha Mitchell interviews Jonah Lehrer about "Proust was a Neuroscientist"

/
The February 9th episode of All in the Mind is an excellent interview of author Jonah Lehrer about his book Proust was a Neuroscientist. In the interview Lehrer reflects on the danger of viewing science as the sole source of discovery, but he also talks a little about several of the people explored in his book. His basic premise is that artists from various fields often intuitively grasped truths that are now being revealed by neuroscience. One example is the insights that Proust had about memory. Proust was a Neuroscientist is a valuable contribution to the current exploration of the relevance of neuroscience to everyday life. It can be easily read in a few sittings or savored one artist at a time. Natasha Mitchell is an excellent interviewer because she always asks interesting and probing questions. (I think of her as the Australian Terry Gross.). All in the Mind is an excellent compliment to the Brain Science Podcast. Mitchell has recently begun an All in the Mind blog and there is a new All in the Mind group on Facebook.

Brain Science Podcast celebrates its 1st Anniversary (BSP 27)

/
brainscience-logo1.jpg Episode 27 is a look back on the first 26 episodes of the Brain Science Podcast. I look back on some of the main topics that we have explored including memory, consciousness, emotions, decision-making, body maps, and plasticity. Then I talk a little about what I hope to do in the covering year. This episode is a little more personal than most, and will mainly be of interest to regular listeners. It includes some ideas about how you can help the Brain Science Podcast grow and prosper. However, in preparing this episode I went back over the past year's episodes and I have prepared a list of all the episodes so far and the main topics. This should help both new listeners and regulars to find episodes that pertain to particular topics. Click here for a brief summary of episode 1-26 with links to the audio files.

/
fib-thumbnail.jpg The lastest episode of Futures in Biotech (FiB 20) is an interview with Dr. Eric Kandel, who won a Nobel Prize in 2000 for his discoveries about how memory works. I think you will enjoy listening to Dr. Kandel's interview. I discussed Dr. Kandel's book In Search of Memory in episode 3 of the Brain Science Podcast. I also discussed his textbook, Memory: From Mind to Molecules in episode 12. For anyone who would like to go back and listen to these episodes, I have provided direct links to the audio files below: #3: In Search of Memory #12: Memory: From Mind to Molecules
