Transition of nervous activity from signals to information processing.

The author starts from the fact that although the signals are the information bearers, they cannot be identified with the information they are carrying. Therefore, in order to achieve control as adequate as possible of human behaviour, the nervous system has to discover the information brought by different signals. The activity of information discovery is realized by means of superisation process, that is by means of transition from many lower order signals to a superior order signal. By means of the superisation process a gradual recognition of the respective signals emitting sources is realised. This recognition is made with the help of certain logical circuits representing the models of different sources written in the structure of the neuronal network. In this manner the nervous system passes step by step from control by means of signals to control by means of information by which the superior structures thereby exert much more subtle control, and supervise the inferior structures working by signals. But, because this control cannot remove all the errors of the inferior structures, different psychical and psychosomatic illnesses can occur.
