ABSTRACT
Sleep and general anesthesia have been described as distinct states. However, several studies have found common neural circuitries, and shared mechanisms between these two states. Sleep spindlesand K-complexes can be evoked by external stimulation during NREM sleep. We recorded cortical burst activity synchronized toauditory external stimulation in isoflurane- anesthetizedrats. We hypothesize that sleep spindles, K-complexes, and bursts evoked by external stimulation might have a common neuronal generator and perhaps similar neurophysiological meaning.
