[Characteristics of slow electrical potentials in healthy subjects and in patients with various forms of neuroses].

The shapes of the slow brain potentials--conditioned negative wave (CNW) and postimperative negative wave (PNW)--were compared in normal and neurotic subjects. Instruction-directed performance was used to investigate the physiological mechanisms of neuroses and to develop the diagnostic psychophysiologic tests with simultaneous recording of the slow potentials. These were evaluated by calculation of asymmetry and power amplification coefficients for CNW and PNW while more and more complicated instructions were given.
