Brain Science Podcast #31: Brain Rhythms with György Buzsáki

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 PodcastDr. 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.

          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.
