The Comparative Anatomy and Histology of the Cerebellum was first published in 1972. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. This is the third and final volume of the late Dr. Larsell's definitive work on the cerebellum, brought to completion for publication by Dr. Jansen. Two additional contributing authors for this volume are Enrico Mugnaini, M.D., and Helge K. Korneliussen, M.D. The first section of this volume deals with the morphology of the human cerebellum. The morphogenetic development, the fissure formation, and the differentiation of the cerebellar lobules are described in detail, and followed by a comprehensive account of the adult cerebellum, its lobes and lobules. It is shown that the ten major lobules which Dr. Larsell distinguished in other mammals are recognizable also in man. Chapters on the cerebellum connections include detailed accounts of all afferent and efferent cerebellar tracts. A subsequent chapter, by Drs. Jansen and Korneliussen, is devoted to the fundamental plan of cerebellar organization. The final chapters, by Dr. Mugnaini, deal with the histology and cytology of the cerebellar cortex. A comprehensive account is given of electron micrographs, a virtual atlas of the ultrastructure of the cerebellar cortex, illustrate the description.
