It has been shown in experiments on three rhesus monkeys that an enhanced stress of analytical-synthetic processes consisting in learning to differentiate a sequence of tones, leads to neurotic disorders of monkeys higher nervous activity. They are manifested individually and consist in disturbances of general behaviour, in forced movements, breakdowns of differentiations, the missing of positive responses in the previously elaborated conditioned stereotype and in typical dynamics of the formation of positive and negative conditioned reflexes to a chain of tones (2000 + + 4000 c/s; 2000 + 2000 c/s; 4000 + 2000 c/s; 4000 + 4000 c/s).
