I have prepared a transcript of Dr. Ginger Campbell's Episode #31, Brain Rhythms with Györgi Buzsáki, with her permission.
You can read it here: Synchrony and Oscillation in the Brain.
The transcript was written to assist my own learning of the material in both the book and podcast. Here is a link to Brain Oscillations: Ten Part Series, on the same topic.
The ideas in the podcast are much easier to follow if one can read along as one listens; the intention of publishing this transcript is for it to be a listening/learning aid for anyone who wishes to dig deeper into understanding the presentation, and the book upon which it is based.
