Conclusions

  1. 1.

    The creation of emotional tension in a regimen of recognition of a meaningful light stimulus resulted in the isolation of two groups of subjects (with an improvement and a deterioration of the quality of activity according to psychometric parameters).

  2. 2.

    Optimum recognition in a state of emotional tension occurs at reduced correlation coefficients of the biopotentials of intrahemispheric leads compared with the state of operative calm for the subjects of both groups.

  3. 3.

    Optimum recognition in subjects with an improved quality of activity occurs against the background of a decline in the degree of correlation of the potentials of symmetrical frontal regions of the neocortex, while in subjects with a deterioration ofactivity, against the background of an increase in the degree of correlation.

  4. 4.

    The structure of the intrahemispheric cross-correlation coefficients prior to a brief or prolonged recognition time and prior to stimulus nonrecognition that was demonstrated in a state of operative calm was retained for subjects with an improvement of the quality of activity during emotional tension; in subjects with a deterioration of the quality of activity the structure was altered for half the investigated pairs of leads.
