metadata.value: The fourth chapter is devoted to the analysis of changes occurring in reactive EEG patterns in
  disorders of the functional state of the central nervous system associated with vascular pathology
  of the brain. The coefficients of photic driving and holding and the energy increase times gained in
  EEG patterns of patients with dyscirculatory encephalopathy differ significantly from the parameters determined for the healthy subjects. When studying the changes occurring in reactive EEG
  patterns under the influence of rhythmic photostimulation, it was shown that various disorders
  of the functional state of the nervous system arising in vascular pathology of the brain of varying severity (initial manifestations in the form of vegetative vascular dystonia, more pronounced
  manifestations as a result of hypertension and vertebrobasilar insufficiency), manifest themselves
  as features of the brain to respond in a certain way to a given rhythm. It was shown that a healthy
  person is characterized by the absence of a reaction to assimilate an external rhythm or an insignificance of this reaction, associated with the absence of an increase in the energy of the wavelet
  spectrum near the frequency of photostimulation, which reflects the predominance of internal
  synchronization of the neural structures of a healthy brain. With an increase in the instability of
  neurodynamic processes, leading to the involvement of a larger number of neural ensembles in
  the pathological process, the destruction of internal synchronization occurs, which explains the
  increase in the quantitative indicators of the rhythm assimilation reaction in persons with essential
  hypertension and with vertebral-basilar insufficiency.
