Formation of auditory streams

The article outlines various neural processes underlying auditory scene analysis. It refers to the processes by which the auditory system groups and segregates components of sound mixtures to construct meaningful perceptual representations of sound sources in the environment. The article gives an overview of sequential, simultaneous, and schema-based auditory perceptual segregation/grouping processes. Emphasis is placed on the relationship between neurophysiological studies of auditory scene analysis in humans and those involving animal models. General physiological principles and themes that have emerged may provide a framework for the continuing investigation of neural substrates underlying auditory perceptual organization. A greater understanding of neural mechanisms involved in processes of auditory perceptual organization suggests additional therapies or other forms of intervention to ameliorate deficits contributing to developmental language disorders.
