Excerpt from Anatomical and Physiological Studies on the Growth of the Inner Ear of the Albino Rat Thus determinations have been made on the diameters of the cells of the ganglion spirale and of their nuclei at different ages; of the nucleus-plasma ratios and of their growth in relation to those of other portions of the membranous cochlea. For the cells of the vestibular ganglion similar determinations were also made. Finally, these results have been compared with those Obtained from the study of other craniospinal ganglia in the albino rat. In presenting my results I shall begin with a description of the changes in the larger portions of the membranous cochlea and pass from these to the cell elements themselves, and then to the observations on the ganglion cells and to the correlation between hearing and the growth of the cochlea.

Auditory Physiology and Perception documents the proceedings of the 9th International Symposium on Hearing held in Careens, France, 9-14 June 1991. The aim of the symposium was to promote exchanges between hearing scientists working with different approaches from cell biology to psychology. The volume is organized into 10 parts. Part I contains papers on the biology of inner ear cells. Part II presents studies on auditory periphery functioning. Part III examines frequency selectivity while Part IV contains papers that deal with the subject of pitch. The papers in Part V examine the coding of intensity. Parts VI and VII discuss temporal analyses and spectral shape analysis, respectively. Part VIII takes up spectro-temporal processing. Part IX covers binaural interactions and sound localization. The studies in Part X focus on pathologies, such as the relations between evoked otoacoustic emissions and pure tone audiometry and the effect of short duration acoustic trauma on activity of single neurons in the ventral cochlear nucleus. The final chapter of the text is a tribute to Professor Zwicker, a leading scientist in hearing, who passed away some months before the symposium.
