[Habituation of evoked potentials in subjects with high, medium and low levels of anxiety].
The habituation of the peak-to-peak amplitudes of N1P2 and P2N2 complexes of the evoked potentials as responses to series of the increasing number of visual and acoustic stimuli was investigated in 55 male and female volunteers aged 20-30. The size and speed of the habituation process were approximated by hyperbola. The shape and coefficients of the hyperbola were correlated with high, medium and low levels of the anxiety and probably reflected the balance between synchronization and desynchronization processes in the cortex.
