[The spatial synchronization of cortical bioelectrical activity in different degrees of severity of alcohol dependence]. / Prostranstvennaia sinkhronizatsiia bioélektricheskoi aktivnosti kory pri alkogol'noi zavisimosti raznoi stepeni tiazhesti.

Stage-II alcoholics were examined 1-2 weeks after drinking periods, as were alcoholics during remissions lasting for 0.5 to 6 years. EEG was recorded by 10 symmetrical leads: prefrontal, central, motor, sincipital, and temporal. Analysis of EEG correlations revealed reliable differences between the two groups in the total level of synchronism of cortical biopotentials, in activities of different regions, and in time course of relationships of various areas during hyperventilation and without it. The data may be used as objective criteria in assessment of the degree of a pathologic process in the CNS and for differentiating the patients by this sign for further differentiated therapy.

[Estimation of time intervals during exposure to a static load]. / Otschet vremennykh intervalov v usloviiakh vozdeistviia staticheskoi nagruzki.

Ten healthy subjects from 17 to 23 years old participated in the study. The subjects had to hold the ergograph load with their right hand thus fulfilling a static work. The effort magnitude was 50 per cent of maximal value of voluntary strength. The subjects pressed the button on the ergograph handle with their thumb depending on the experimental conditions and held it for 0.8 or 2.5 s. The work with each interval included three conditions: interval estimation without static load (SL), the same with the SL and after SL. At the end of experiment the subjects worked with the interval of 2.5 s under the conditions of maximally long SL holding as far as it would go. An increase of reaction time (RT) was observed at the transition from simple button pressing to interval estimation. RT tended to increase with prolongation of a standard interval. SL did not influence significantly the RT value if it did not cause the general fatigue. A gradual increase of interval estimations was observed under the influence of SL the interval of 0.8 s being estimated more accurately. Estimation of various intervals was supposed to reflect different mechanisms of their perception. Estimation of the interval of 0.8 s was based on the memory trace processes and that of 2.5 s interval was connected with conditioned reflex activity. Apparently SL did not influence interval estimation directly but by changing the functional state of the subject's organism it predetermined a prolongation of the interval estimations.
