title: [Contingent negative variation and endogenous components of the evoked potential].
abstract: After having evoked the problems raised by the definition of the different endogenous components of evoked potentials, the author reviews the experimental data related to contingent negative variation (CNV), the processing negativity, the N200, P300 and the slow waves (SW1 and SW2). Their characteristics of amplitude, latency, duration, topography and their functional significance are examined. Then, the particular point of these waves' variability is pointed out, in relation to maturation, level of arousal and personality. Finally, the different theories which preside over their interpretation are reviewed.
