| The even-related potentials are good indices of brain functions duringsleep stages. The contingent negative variation (CNV), occurring in the interval between a conditionaland a target stimulus, reflects information processing. The emitted potential which occurs when an expectedstimulus is omitted reflects the access to a specific memory. During waking, deep slow wave sleep (stage4) and paradoxical sleep seven subjects were submitted to a CNV paradigm, the target stimulus of whichwas occasionally omitted. The endogenous components of the evoked potentials induced at Fz, Cz and Pzlocations by the auditory stimuli were analysed during the three behavioral stages. During stage 4 theywere of largest amplitude and longest latency. These results are discussed in terms of neural excitability.CNV and emitted potentials were observed during waking and paradoxical sleep, but not during stage 4.These results suggest that information processing occurs during paradoxical sleep with access to wakingmemories during this stage of sleep, whereas information processing is absent during stage 4. | ||
