More on Brain Oscillation (from the Human Anti-Gravity Suit)

/
Diane Jacobs has put a great deal of effort into digesting Rhythms of the Brain, by György Buzsáki.  She has just finished an extensive discussion of Buzsáki's interview in Episode 31 of the Brain Science Podcast.  You can find this series on her blog, which she calls the Human Anti-Gravity Suit.  She has also done a transcript of the episode that we are going to post as soon as we get some final corrections from Dr. Buzsáki.

Reflections on Brain Oscillations

/

A recent episode of the Brain Science Podcast was an interview with György Buzsáki author of Rhythms of the Brain.  The significance of brain oscillations is a complex and somewhat controversial subject, so it is not surprising that the episode had generated mixed reviews.  It is quite challenging to present an area of this sort, and I thought Dr. György Buzsáki did a good job of putting his work into layman's language.

I chose Rhythms of the Brain because several listeners requested it.  One of those was Diane Jacobs, who is an energetic contributor to the Brain Science Podcast Discussion Forum.  In a recent blog post Jacobs explains why this subject has captured her interest.

Jacobs is currently working on a transcript of the episode (31), which I will post when it is available.  I want to publicly thank her for her efforts.  You can read her blog post at http://humanantigravitysuit.blogspot.com/2008/03/oscillatory-matters.html.

Brain Science Podcast #31: Brain Rhythms with György Buzsáki

/

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.

  • 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.
