1. Cycle 8: Gamma oscillations
Why gamma gives good buzz
[50 Hz = 20 ms period]
Self-organizing cell assemblies group in ms windows
The time constant of PSPs leads to best integration of inputs received within 30 ms
Best window for synaptic plasticity within 40 ms

2. Cycle 8: Gamma oscillations
Best window for synaptic plasticity within 40 ms

3. Cycle 9: Gamma oscillations
Gamma mechanisms – external and internal generation
stimulus-locked (evoked) activity competes with induced gamma
