[Coupling behavior of central nervous system functions as well as heart rate and respiratory rhythm under the influence of diazepam].

In order to substantiate the subjective feeling of relaxation and mental balance felt after taking Diazepam a new biorhythmometric technique was used, in which the minute-rhythm pulsations were calculated with the aid of autocorrelation analysis from the time series of central nervous functions and cardiorespiratory functions, and their frequency synchronisation recorded as to quantity in the form of a coupling factor. Proof of an improved central nervous co-ordination was that the coupling factor of a relatively uniform test team, all students, after administration of Diazepam (Faustan) was significantly higher than before. If one assumes that the psychosomatic illness, for which the use of Diazepam is considered advisable, are a manifestation of generally disturbed central nervous vegetative reaction condition, then the biorhythmometric survey of the internal co-ordination of relevant physiological functions provides stronger proof than testing with single parameters, between which we also found significant variations (for example, prolongation of the sensorimotor reaction times under Faustan).
