This paper is devoted to the evaluation of psycho-physiological parameters and element status of students with different types of functional interhemispheric asymmetry (PMA), in the process of determining the profile of functional interhemispheric asymmetry (PMA) revealed that the majority of surveyed showed signs of dominance of the left hemisphere of 73 %, while the number of students was 15 pravodominantyh % of people with clearly pronounced asymmetry revealed only 12 %. In identifying the psychological characteristics were as follows: the students' performance levodominantnyh «physical aggression» (p ≥ 0.01), «indirect aggression» (p ≥ 0.01), as well as the main integral index «index of aggressiveness» (p ≥ 0.05) were significantly higher compared with pravodominantnymi students. As a diagnostic biological media have been used hair. Using the method of mass spectrometry and atomic emission spectrometry with inductively coupled argon plasma is investigated by the contents of 25 chemical elements in hair of students with different types of functional interhemispheric asymmetry (PMA). For the first time obtained data on the characteristics of elemental status of persons with different types of functional interhemispheric asymmetry (PMA), manifested in the significant difference of the chemical elements such as potassium, sodium, silicon, and cadmium. Found reliable and approaching them direct correlations with psychophysiological measurement of the properties of attention for Ca, I, Mg, Mn, Se, Li, p < 0.05. As a result of the test, «Immunity», revealed the correlation with the level of attention of several metals in the body of students, such as - Ca, Fe Co. As a result of the test «Simple visual-motor reaction» credible and approaching him correlation was found for the AL, Li, Mn, Fe. Correlation of sensorimotor reaction rate on the test results «response to a moving object» for Cd, Co, Fe. Na density correlations for all cases ranged between 0.4 < r <0.7 for the probability of 90-99,2 %.
