Key to understanding the neuronal basis of consciousness is the characterization of the neural signatures of changes inlevel of consciousness during sleep. Here we analysed three measures of dynamical complexity on spontaneous depth elec-trode recordings from 10 epilepsy patients during wakeful rest (WR) and different stages of sleep: (i)...

During non-rapid eye movement (NREM) sleep (stage N3), when consciousness fades, cortico-cortical interactions are impaired while neurons are still active and reactive. Why is this? We compared cortico-cortical evoked-potentials recorded during wakefulness and NREM by means of time-frequency analysis and phase-locking measures in 8 epileptic...
