[Assessment of human mental performance through registration of working gain of quasi-stable brain potential]. / Opredelenie umstvennoi rabotosposobnosti cheloveka putem registratsii rabochego prirashcheniia kvaziustoichivogo potentsiala golovnogo mozga.

A novel method of assessment of mental performance in man (MP) is proposed. It is based on relationships between MP, energetic processes in deep cerebral structures and relevant values of quasi-stable brain potential (QSBP). The measurements can be made by persons without special training having simple equipment. MP is assessed by working gain of QSBP after intersive brain work for 0.5-1 hour. If the gain is above 20 mV, MP in children over 10 years of age and adults is considered high, 20 to 10 mV--as moderate, 10 to 0--as satisfactory, under 0--as unsatisfactory. The method has been successfully tested in practice and has certification.
