Abstract

Abstract The cerebellar lobules receiving trigeminal afferents, crus 2 and paramedian, and the lingula which receives only vestibular and spinal afferents were studied. Time and the modality of development were compared with earlier experiments carried out on other trigeminal cortico-cerrebellar areas. A close connection between quantitative and qualitative aspects of afferents and one type of growth was demonstrated. There was correlation between various morphological features of the cerebellar area and the stages of genesis of masticatory function. Maturity of the certain lobules of the cerebellar cortex corresponded to the onset of weaning. Thus, the development of cerebellar structure seems to run parallel to progressive synergic musculo-mandibular activities associated with certain primary and secondary neuronal tracts.
