[Trends and problems in psychophysiologic research].

Considering the increasing importance of psychophysiological investigations, the peculiar quality of psychological control functions in human organism is stressed. For this reason, specific definition of the initial conditions for psychophysiological experiments is necessary. If we use complex experimental schedules including electrophysiological parameters more and more differentiated results can be obtained. The different ways of information storage within the two hemispheres are considered as very conclusive. By means of a model of motor system the significance of internal feedback circuits is demonstrated. A statement concerning the mutual connections between biological and psychological events is given.
