| Abstract | The primary goal of the auditory system is to analyze acoustic signals and to interpret what is occurring where efficiently and stably to guide appropriate actions. To achieve this, the outputs of the frequency analyses in the auditory periphery must be organized, so that the frequency components or acoustic features arising from the same sound source are grouped together. Recent evidence suggests that the process of perceptual organization is much more active and highly selective than previously thought, involving dynamic interaction of bottom-up sensory analyses and top-down predictions. We have been studying the dynamics of perceptual organization phenomena such as the auditory streaming, the continuity illusion, and the verbal transformation illusion, combining various approaches including psychophysics, brain imaging, and modeling incorporating neural dynamics. I will present preliminary results. |
