  • Title: [The effect of the rate of movement of a sound image on human long-latency auditory evoked potentials].
    Author: Vaĭtulevich SF, Pak SP.
    Journal: Zh Evol Biokhim Fiziol; 1990; 26(6):772-8. PubMed ID: 2092559.
    Abstract:
    In 10 healthy subjects, studies have been made on changes in amplitude-temporal characteristics of N1-P2 components at different rates of movement of a sound image (3.14, 1.57 and 0.78 rad/s). It was shown that only movement of the sound image from the right ear to the median line of the head with sufficiently high rate (3.14 rad/s) results in the increase in total peak amplitude of N1-P2 components relatively similar parameters obtained during the effect of a resting sound image lateralized at the same ear. Latent periods of N1 component in both hemispheres are longer during the effect of the moving sound image than during the effect of the resting lateralized one, although with the decrease in the rate the difference becomes less significant. It is suggested that the right hemisphere is more sensitive to changes in the rate of movement of the sound image.
