[Inertial processes in the auditory system during localization of moving sound sources].
The significant role of inertial features of the auditory system in localization of moving sound sources is presented. This inertia requires some time of observation about the movement in space of the auditory signals. Slower time of estimation of the localizing features of the moving sound source (as comparing with the unmoving one) is followed by the appearance of new important possibility of the auditory system, namely in perception and analysis of the parameters of moving sound sources. Meanwhile these inertial features are manifested by another significant change in the activity of the auditory system. After the cessation of the auditory signals we observed some aftereffects which manifested that the subjective perceived trajectory of the moving sound source is lengthening toward the direction of the existing movement even when the auditory signal is switched off. Stated above can serve as an evidence of presence in the auditory system some predictive possibilities concerning the direction of moving sound sources. This feature is essential from biological point of view for an adequate organisation of behaviour of the subjects.
