[Working conditions and functional body stress of operators in the television video recording centers].

In order to determine the ways for prevention of operators' overstrain, the working conditions and functional body stress were dynamically studied during the 12-hour shift by means of TV video-recording. The majority of operators experienced some neurologic disorders, high rates of situational and personality anxiety and an elevated level of neurotism. Mean rate of potential systoles was 75 +/- 2 per min, systolic arterial pressure 114 +/- 2, diastolic AP 74 +/- 2 mm of mercury column.

[General patterns of the sensory processes in exposure to extreme stimuli].

A series of changes in sensory sphere take place in conditions of extremal and unusual influences. These changes are determined directly by processes at the receptor level and indirectly--by the central interaction. In spite of great variety of the influences, there are some general laws in changes of functional state of afferent systems analogous to biophysical and neurophysiological processes.
