Illustration 6
The
three-way structure of the rhythmic functions in the autonomic area with periodic
duration underneath the day.

(According to HILDEBRANDT 1986)
The shorter wave
rhythms of the spectrum, however, (illustration 1, underneath the day rhythm)
are purely endogenous autonomic functional variations which have no immediate
link to the rhythms of the environment. Instead, a special organisational
principle shows itself in this area (illustration 6): So you find the
highest frequency rhythmic processes in the area of the nervous system. They
serve here to change information, i.e. for the absorption, transportation
and processing of information which is encoded into rhythmic signals.
The slow rhythms of the autonomic area, however, primarily serve the metabolism
and its functional areas. They regulate the intake and excretion of substances,
digestion, secretion and energy storage.
While the informational rhythms are strictly bound to highly differentiated spatial structures of the nervous system, the metabolic rhythms more or less concern all tissue and are spatially much less specified. The system of the rhythmic functions of transportation and distribution is the transition between these two completely different functional areas, especially with the rhythms of circulation and breathing.
