| Outline of Final Research Achievements |
Natural sounds are always complex in a temporal aspect, and our brain must have specialized neural circuitry which is involved in the analysis of such complex sound, although the anatomical and physiological basis of the analysis is poorly known. In this study, we studied the input and output properties of local circuit of the inferior colliculus, which is the first integration center of many aspects of auditory information, with combination of physiological and anatomical techniques at a single cell level. From the results, in the inferior colliculus auditory information is represented not only by spatial assembly of each neurons but also by cell types. The data also suggested that some of the responsiveness to complex sounds is created de novo by local circuitry of the inferior colliculus.
