[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. The evaluation of functional state of sensory systems in such conditions can only proceed on ergonomic base taking into consideration the sensory fatigue as well.
