A case of anoxic encephalopathy is reported, with study on a whole-auditory-pathway basis, and the method of processing tissues is outlined. Pathologic changes are found throughout the central part of the auditory pathway. The importance of including the superior ventral cochlear nucleus (SVCN) with cochlear structures in correlating findings with audiometric data is supported. The previously advanced tonotopic frequency pattern, with zonal vulnerability, of the spheroid cells of SVCN is supported.
