- •
Slow-delta oscillations that alternate with gamma oscillations (gamma burst) occur with ketamine at general anesthesia levels.
- •
Gamma, theta and decreased alpha/beta oscillations are not unique to ketamine at general anesthesia levels.
- •
The gamma burst pattern may result from circuit disruptions in cortical and subcortical sites.
