[Evoked potentials: their spatial physiological characteristics and the problem of their functional assessment]

Basic data about physiological evoked responses properties of the brain structures highest level (telencephalon) are presented. Contemporary ideas concerned to mechanisms of these responses are summed up. Data about their distribution in telencephalic structures and morphological basis of the distribution are adduced. The evoked responses especialities of telencephalic structures in awake animals in chronic experiments are revealed. The functional significance of processes that form this bioelectrical reaction is observed. Special attention is paid to earlier (to 100 ms) components. The possibility to use the evoked responses as the functional instruments of investigations of the brain is discussed.
