title: Distribution of cerebellar mossy fibers arising from neurons of the raccoon main cuneate nucleus.
abstract: The present study demonstrates that fibers originating in the raccoon main cuneate nucleus are not segregated in specific cortical regions of target cerebellar folia as reported in studies of the cat cuneocerebellar tract. This observation supports the hypothesis that exteroceptive and proprioceptive divisions of the raccoon cuneocerebellar tract do not exist as distinct structural entities. The findings of this study do not preclude the possibility that projections from the external and main cuneate nuclei are segregated within the cerebellar cortex on the basis of functional modality rather than nucleus of origin.
