*f (**−n)* and *f (n)*.
The concept of the uniformity in this case is spread both to the
semantics, and to the statistics, or to this or another together. Separation with time can or cannot be absent. The
information
content at frequency *f* (0), naturally, can not depend upon the
information transmitted at frequencies *f (**−n)* and *f
(n)*. This is explained by
the specific place of the central source in system, and also by the
symmetry of the system with respect to the central frequency *f* (0).
Condition (5) can serve as on of the simple conditions for
fulfilling
conjunction (9). Von Horner concentrated his attention on it in the
above mentioned work. It is true that he spoke about an absolute
band
of frequencies, and expression (2) determines the equality of the
relative frequencies, which substantially facilitates the detection
of the frequency *f* (0).
Subsequently after establishing frequencies *f (**n)* and *f (−n) *
track-
ing can be accomplished on frequency *f* (0) according to (2).
2. __Biological Clock__
It is possible to consider the EEG rhythms as rhythms in the
system of counting time. To calculate the approximate values of all
possible periods (or frequencies) of EEG-rhythms it is possible to
use
the following empirical formula (1):
