Long-latency auditory evoked potentials in humans and the localization of a sound image

In the article, we discuss data from an investigation concerning how boundary conditions for the creation of sound-image movement are reflected in long-latency auditory evoked potentials and discuss how an important feature associated with the human localizing function (resistance to interference during the localization of both a stationary and a moving sound image) appears in long-latency auditory evoked potentials. We establish that a change in the parameters of a signal creating a sensation of sound-image movement results in an exhaltation of the amplitudes of the N₁ and P₂ components. The effect of binaural freedom from masking is reflected in these same components of long-latency auditory evoked potentials during movement of spatially shifting signals.Translated from Fiziologicheskii Zhurnal SSSR imeni I.
