Projection of the cochlear and lagenar nerves on the cochlear nuclei of the pigeon

The purpose of this investigation is to determine, by experimental degeneration methods, point to point afferent neuronal connections between the organ of Corti and the primary cochlear nuclei of the pigeon, and to clarify the central termination of the closely associated nerve from the macula lagenae. At the present time, fundamental problems concerning audition in man and higher mammals are being attacked by electrophysiological experimentation on lower forms. This approach should consider comparative anatomical data, some of which this study is intended to provide. Furthermore, a detailed anatomical knowledge of the more simply constructed avian auditory mechanism is necessary to provide a better understanding of the evolution of the auditory system and to serve as a basis for future morphological and physiological investigation.
