[Comparative study of methods of active effects on human brain to reveal abilities of low level perception].
Active methods of the influence upon the person with the aim of forming special states of the brain in order to obtain reproducible and strong perception of low level signals are compared. If the human brain is immediately exposed to the force by penetrating physical fields (i.e. magnetic, electromagnetic, acoustic) than best results can be obtained while using electromagnetic and acoustic fields; in this case the effectiveness of the tests on perception grows from (50 +/- 6) to (79 +/- 9)%. If the brain is forced through the peripheral sensory systems (visual and acoustic analyzers and skin receptors) than perception grows from (50 +/- 6) to (85 +/- 10)%. Special device for influence upon the brain through visual analyzer with the help of bylatheral photo-stimulation is described. The outlook of the control upon special states of brain with the aim to reveal abilities to the low level perception is discussed.
