extremely close to the Gaussian while the densities of the time intervals of a clipped signal are clearly and orderly determined. The average length "of a period" of rhythm is a function of its ordinal number. These and other discovered regularities in the structure of EEG rhythms make it possible to assume that the spectrum of zeros of an EEG appears earlier than the spectrum of amplitudes and the latter are shaped according to any simple principle, for example a optimum band of frequencies.
It is possible evidently to base a further analysis of the EEG signals on the following natural premises. Let there be a certain autonomous system of signals, the role of which, in particular consists of the following:
a) to give the possibility to a correspondent to discover a previously unknown frequency of the source of information;
b) to synchronize in the known meaning the work of the separate subsytems and the organs of the system;
c) to continuously transmit on many channels information in all direction (similar to broadcasting) with the aid of a certain code.
The problem of detecting the source of information, the statistical and semantic characteristics of which previously nothing was known, is examined in work . The system of signals proposed by Von Horner, which serve this purpose is wonderfully similar to the system of clipped EEG signals although there is also a number of substantial differences. Nevertheless one must not pass this surprising analogy.
The second question which refers to synchronizing the work of the subsystems and organs of the system, is associated, apparently, directly with problem of the so-called biological clock. In recent years we became witnesses to how fruitful the idea was of condensing the channels of communications, for example, in radio relay lines. It falls completely into this representation and the presence of many EEG rhythms, which form a parallel, and at the same time in every
