    • Gamma activity and synchrony, which have been viewed as possible correlates of consciousness (26-28), were found to be low in NREM sleep in one study (29). However, they were equally low in REM sleep, when conscious experience is usually vivid, and they can be high during anesthesia (30). Moreover, intracellular recordings show that gamma activity persists during NREM sleep (31), and other studies report that gamma coherence is a local phenomenon that does not change between wakefulness and sleep (32). Large-scale synchrony in the alpha and theta bands may also correlate with conscious perception during wakefulness (33), but synchrony in these frequency bands actually increases during NREM sleep (3, 34).

    • A change in transcallosal responsiveness between wakefulness and sleep was observed in an experiment employing electrical stimulation of the corpus callosum and extracellualar cortical recordings in monkeys [figure 8.19 in (35)]. Changes in TMS-evoked motor responses during sleep and after awakenings from different stages of sleep have also been reported (36, 37).
