Cycle 8: Gamma oscillations Why gamma gives good buzz [50 Hz = 20 ms period] Self-organizing cell assemblies group in 15-30 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

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

Cycle 9: Gamma oscillations Gamma mechanisms – external and internal generation stimulus-locked (evoked) activity competes with induced gamma ..see Cycle 10, p.263 “Evoked activity…”
