Fast Oscillations in Cortical Circuits
Roger D. Traub et.al., 1999

Preface
The approach of this book is to analyze the firing patterns in large networks of neurons using a combination of electrophysiological and computer modeling techniques. It was found that burst synchronization depended on

The goal is to understand the effects of beta (10-25Hz) and gamma (25-80Hz) oscillations in both normal and epileptic conditions.

1. Oscillations: What They are, What They Might Be Good For
Gamma frequency (>30Hz) oscillations have been observed by some, denied by others. The difficulties are discussed -- uncertain areas of involvement, averaging across too large a distance, ... The question is whether such oscillations are significant for higher order brain function. Differences between normal and epileptic situations are discussed.

2. Single Hippocampal Pyramidal Cells

3. Single Hippocampal Interneurons
Differences are observed between the spiking responses of CA1-area and CA3-area pyramidal cells. These seems to depend primarily on ion channel conditions.

4. Synaptic Interactions in the Hippocampus

5. Networks of Pyramidal Cells: Synchronized Bursts

6. Networks of Interneurons I: Synchronized Bursts

7. Gamma Oscillations in Vivo

8. Networks of Interneurons II: Gamma Oscillations in Vitro

9. Gamma Oscillations in Networks of Interneurons and Pyramidal Cells in Vitro I: Mechanisms of Synchronization

10. Gamma Oscillations in Networks of Interneurons and Pyramidal Cells in Vitro II: Synaptic Plasticity and the Switch to Beta Frequencies

11. Conclusions: Are Gamma Oscillations Significant for Brain Function?
