Investigation into the mechanisms of the individual psychophysiological adaptation to life-threatening situations was performed. The data analysis of evoked potentials induced with verbal stimuli in 30-50-msec exposures was executed. Cross-correlation and wavelet analysis, as well as neurone algorithms were used to define total brain response to each stimulus and its duration. Correlation of the estimated parameters with subconscious aspects of psychic activity is discussed. Results of the studies performed with this neurosemantie method in various groups of subjects perceiving threat to life in the course of their performance, are presented. Described changes in the subconscious response mechanisms can help to clarify the direction for creation of new approaches with psychological correction and support.
