The histological sections themselves were digitized and stored in the computer in order to measure the volumes of whole brain, cerebellum, and vermis. The area of interest was outlined, threshold intensity set, and the area of each section measured. Volumes were calculated by multiplying the sum of the areas of each structure by the distance between sections, each structure averaging 25 sections. All fixed volumes were multiplied by a shrinkage factor that corrected for the inevitable shrinkage of the tissue during fixation, embedding, and other histological procedures.
Whether this reorganization of information applies to all cerebellar afferents remains to be seen (Schmahmann, 1996), but the structure of cerebellar organization would indicate that it is able to process information in a unique way and is not parroting the information processing pattern of the cerebral cortex.
The expansion of the nuclei was not in tandem. The principal inferior olivary nucleus increased with the cerebellar hemispheres and showed a positive grade shift relative to the whole brain volume (Figures 8 and 9). The dentate nucleus did not show a positive grade shift relative to the whole brain volume and actually showed a negative grade shift relative to the cerebellar hemispheres. The human dentate was far below the volume that would be expected from either monkey or ape hemisphere and cerebellar volumes (Figures 10 and 11).
