[Bioelectric brain activity in patients with neurotic disorders].

Seventy-three patients with neurotic disorders, aged 14-35 years, and 33 healthy controls have been examined using electroencephalographic method with spectral analysis of EEG, which has been conducted on the Brain Surfing system by the algorithm of direct Fourier transformation. The patients had changes of brain electric activity manifesting as insufficiency of thalamo-cortical synchronizing systems that caused an excessive activating effect of reticular formation on the cortex realized through extrathalamic reticular cortical and septo-hippocampal activation paths. Determinative in electrophysiological brain organization was the theta-rhythm, a marker of excessive emotional and autonomic activation, which directly correlated with an extent of personality accentuation and severity of neurotic state.

[Specific features of the structure of sleep and personality under the conditions of chronic emotional stress and methods of improving the adaptive abilities of man].

The results of a complex psychophysiological study of human sleep in the chronic stress condition are described. 20 patients with complaints of night sleep disturbances in the chronic stress condition and 10 healthy controls were examined by polysomnography. Profound changes of the quantitative and qualitative sleep parameters, mainly, related with the slow sleep phase, sleep delta characteristics and adaptive wakefulness mechanisms.
