This volume represents a significant step toward a better understanding of integrative functions of the central nervous system (CNS) containing contributions on EEG, evoked potentials, event-related potentials, contingent negative variation (CNV), and magnetoencephalography. The discussion focuses on neuronal networks, a new nonlinear approach toward analyzing CNS field potentials, the significance of various current source densities, and investigations on the cellular level using multielectrodes. Epilepsy models and computer-aided investigations of pathologic changes in the CNS round off this survey of topics of current interest in this rapidly developing field.
