Analysing heart rate variability (HRV) is nowadays one of the methods, allowing relevant ppredictios for the health state, first of all the prediction of different cardiovascular risks. But it also alows a deep psychophysiological interpretation which can open the door for identification of conscious and unconscious processes of human. So is imortant in social inphysiolog. Based on different physiological mechanisms of regulating the heart rate, including the influence of segmentar and suprasegmentar levels of vegetative nervous system (VNS) controlling the HRV. It's one of the most objective and non-invasive methods to look inside of working processes of the VNS. Due to the alalysis of complexity we obtain information of influence of the central nervous system on the regulatory systems of the heart rate. This is an important information helping to reveal if a person has neurological network circulating in the central nervous system, being harmful for one's health and/or occasionally for the society. Time domain statistical analysis, which we can represent in form of rhytmogram gives us the possibility to identify whether the investigated person has a dominant (neurological network circulating in the central nervous system) in his brain. Furthermore we can find out if the dominant is circulating in our conscious or in our unconscious. During our investigation we found some criteria for differentiation of conscious vs unconscious dominants: conscious dominants can be detected at a rhytmogram by appearance of spontaneous single waves in direction to tachycardia area; such tachycardia - tendency monowaves appeared at the end of very low frequency (VLF) wave after appearance of low frequency (LF) waves. Their appearance in the end of VLF waves indicates that their origin comes from the central regulatory structures. This means that it's our cognition. The fact that such waves occur with a certain periodicity we can say that these are impulses from a circulating neurological "network” in our brain, which represents a dominant from physiologic point of view. Such a network can be a statement or an idea etc. which doesn't leave the person in peace, e.x. "I have to come in time!" (action during a certain period of time in the presence and the action depends mainly on the person himself). So a conscious dominant is a transitory stress reaction, which is emotionally and cognitively percepted by the person. That it's a stress reaction indicates the close dependence with LF waves. LF waves indicate the activity of sympathetic nervous system, which highly increases in acute stress reactions. In case of a dominant circulating in our unconscious the rhytmogram has other properties : At first: appearance of solitar tachycardia oriented in condition of high frequency (HF) waves, which are responsible for parasympathetic nervous system, assuring our calm and all adaptive reactions. Secondly: No strict VLF- dependence. Third: the appearance is observed when the person feels subjective relaxed, so in calm state. Finally, disappearance in orthostatic probe. A situation which is circulating in the unconscious is not a situation from the presence, it is from the past or from the future, and normally, does not depend directly on the person. A second group of criteria we find by analyzing spectral analysis of HRV in conditions of modeled psychoemotional states. We show some pictures to the context of which we expect from the person to have an emotional reaction. It means that normally we percept emotions by emotional component of perception (we feel emotions) and by the cognitive one (we understand the meaning of emotions ). Of course a normal perception of emotions happens predominantly due to the emotional component. To find out the conscious vs unconscious by observing emotional reactions we showed some pictures the context of which is closed connected to main life principles of a human being. The person is expected to have an emotional reaction which we inregistrate as an increase of segmentar (HF and LF) level of vegetative regulation of the HRV, reading from the spectral analysis of HRV. This is a normal psychophysiologic reaction. That means such a person feels these emotions because consciously he understands its meaning, the reason is his consciousness is ruled by normal live - saving principles from the unconsciousness. An other situation is when under the same conditions a person percepts the emotional ruled situation by the cognitive component (increased VLF spectrum of HRV in the spectral analysis in comparison with the segmentar components - HF and LF). That means in his unconscious is a neurological network which is orientated against human life. It blocks the speed of normally occurring emotional reaction by impulses which come from such a harmful network, circulating the unconscious of such person. In conclusion, we found some metods and criteria to identify persisting impulsatory networks in the central nervous system of human, by deep analysis of heart rate variability with linear and non linear methods. We found criteria to destinguish whether the circulating network comes from a person's conscious or unconscious. Creating conditions of modelled psychoemotional states during HRV measurement, we perform the analysis in order to understand whether the circulating neurological network is dangerous for his own health or if the context of his neurologic network is conected to social harmful threats.
